    tkaiser got a reaction from sfx2000 in Reboot command   
    Just to add another potential reason why reboot seems to not work: since the board gets stuck on u-boot prompt due to some noise on serial RX line or via USB devices. The latter was one of the reasons why we disabled USB in u-boot for H3 boards (still can't remember whether this change made it already in the available 5.14 releases) and we just recently discovered that on NanoPi NEO obviously noisy power sources lead to u-boot waiting endlessly for input on the prompt since it misinterpreted some signals before and stopped autoboot behaviour.
     
    In other words: reboot works perfectly but then the board waits sitting at the u-boot prompt for instructions (had this several times with NanoPi NEO the last days but only when connected to a specific PSU source).
     
    BTW: Since you mentioned contact resistance and also consumption measurements in another thread. Contact and cable resistance might influence your consumption readouts (too much) and on the other hand I did a lot of research/tests the last weeks how to lower idle consumption especially of various H3 based boards. Good starting points might be

    Great. So you got the 'you can run FreedomBox on any computer that you can install Debian on'. Now you just need to know what Armbian is (Ubuntu or Debian userland with optimized kernel and optimized settings), then as long as you are able to accept running an Armbian Debian flavor is in some way comparable to 'running Debian' you can start. If Armbian is not for you for whatever reason simply wait a few months or years until upstream support for recent/decent ARM hardware arrived in Debian.
     
    In case you choose Armbian you need to ensure to freeze kernel and u-boot upgrades since otherwise you use a stable distro on an unstable basis (it seems stuff like this needs to happen from time to time for reasons unknown to me).

    -And I haven't even begun yet.
     
    I think it's important to understand the details on how the boot-process works. Once you have this knowledge, you'll know much better how to get things working if something gets messed up.
     
    The CPU has a small on-chip boot-ROM. In this boot-ROM, there's code that cannot be altered.
    This code is the code that checks the 3 jumper connections; usually these are set to load the boot-loader from SPI NOR-Flash.
    If there's something messed up, you'll not get the "Marvell >>" prompt, but instead you'll get a single "> " - still, don't worry if that happens, because there is a way out.
    When the boot-loader is 'trusted-firmware'-verified, then it is loaded (usually from SPI NOR-Flash as mentioned earlier, but could also be from SATA, UART or eMMC), and finally this boot-loader is executed. The boot-ROM code has now done its job.
     
    The bootloader that was just loaded and executed is usually Uboot (it could be anything; even your own code).
    This bootloader is the one that presents you with the "Marvell >>" prompt and allows you to interrupt the boot-process by pressing for instance space or return.
    If the bootloader is not interrupted by a keypress within the timeout (usually 2 seconds), then it issues one single command automatically:
    run bootcmd
    -This 'bootcmd' is nothing but an environment variable. It contains a string that is executed by Uboot's command-interpreter.
    You can issue this command to see what's in the variable:
     
    printenv bootcmd
     
    My 'bootcmd' looks like this:
    run boot_armbian
     
    -Yours might be different.
    So another environment variable is being executed by the command-interpreter.
    That environment variable holds instructions on ...
    1: Get netboot images - just in case we're netbooting via PXE
    2: Setup boot parameters
    3: Probe the block devices, in order to find the most likely block-device to boot from (such as MicroSD-card/USB/SATA)
       Probing is usually done by the 'test' command. A boot-interface and boot-device is chosen (those are usually kept in environment variables)
       The boot-interface could for instance be "scsi" if you're booting from SATA or "mmc" if you're booting from a MicroSD card
    4: Load the kernel image and emergency image (usually done by the ext4load command)
    5: Execute kernel image (done by the 'iboot' command).
     
    When step 5 is executed, Uboot finished its task and the kernel takes over.
    If something goes wrong, the emergency disk image is brought up.
     
     
    ... If you at some point are at the "Marvell >>" prompt and want to play around, here's a few things you can try out:
     
    If you have a SATA disk connected:
    scsi scan; scsi dev 0:1
    ext4ls scsi 0:1 /
     
    If you have a MicroSD card inserted:
    ext4ls mmc 0:1 /
     
    If you have a USB block-device attached:
    ext4ls usb 0:1 /
    ext4ls usb 1:1 /
     
    The number before the colon is the device number, the number after the colon is the partition.
    -So if you have your rootfs on partition 12 on your SATA drive, then you could for instance ...
    ext4ls scsi 0:14 /bin
    ... to see some of the executable files on that partition.
     
    Note: 'scsi scan' probes the SATA interface; you will not be able to do anything useful with the device without issuing that command.
     
    You can also set some environment variables if you wish to:
    setenv myVariable "echo hello there"
    printenv myVariable
    echo $myVariable
    run myVariable
     
    You should be able to execute the boot instructions one-by-one until you reach 'iboot'.
     
    Let's assume that you've found out how to make your board boot; you've written down all the commands necessary and tested that they indeed boot if you write them exactly as you have them ready (hopefully you have a terminal with copy-and-paste).
    When you've got your commands tested, you can set the environment variables and save those variables to your SPI-Flash using this command:
    saveenv
    Wait for the prompt to return. Make sure you can type on the command-line (thus you will know that the writing is done).
    After that, you can just boot as usual (either by typing 'boot' or 'reset' or by pressing the reset button).
    -Do *not* press the reset button while the flash-memory is being written to; that will surely mess up things.
     
    At this point, you may have tried some of the above; I expect that you're likely stuck somewhere, if so, please let me know where, so we can get you unstuck.

    Nope, lazy mode won (thanks to parted and resize2fs now using the eMMC's full capacity, then did do-release-upgrade to upgrade Vamrs' Xenial image to 18.04 LTS, then quickly checked partition 5 whether latest DT changes are present -- they are).  Then I took two SATA SSDs and one NVMe SSD (in Pine's PCIe to M.2 adapter), threw everything in a corner, connected the stuff and fired it up again:
     

     
    The huge fan is there to generate sbc-bench numbers now almost without throttling. Numbers here: http://ix.io/1nVS -- performance (not so) surprisingly identical to all other RK3399 thingies around but DDR3 memory results in slightly lower memory performance (negligible with almost every use case) and of course those RK3399 boards where we allowed 2000/1500 MHz so far show ~5% better CPU performance. The better cpuminer scores compared to RockPro64 with same 4.4. kernel here are just due to testing with Bionic on Ficus (GCC 7.3) vs. Debian Stretch there (GCC 6.3 -- with some tasks simply updating GCC you end up with whopping performance improvements for free)
     
    Not able to test the PCIe SSD since 'rockchip-pcie f8000000.pcie: PCIe link training gen1 timeout!' (full dmesg output). I guess there's still some work needed to get DT bits correctly for PCIe? Ok, let's forget about PCIe now (there won't be anything new anyway since PCIe lives inside RK3399 so as long as trace routing on the PCB is ok this RK3399 will perform 100% identical to every other RK3399 thingy out there)
     
    Now let's check USB situation. I'm a bit excited to have a look at the USB3 SATA implementation here since on the PCB itself there's a JMS561 controller (USB3-to-SATA bridge with support for 2 SATA ports, providing some silly RAID functionality but also PM mode. PM --> port multiplier). The two SSDs when connected with the JMS561 in PM mode appear as one device on the USB bus:

This chipset can be found in a lot of dual drive external USB3 thingies from various drive manufacturers but I thought we would see it here running with original JMicron firmware There's a Genesys Logic USB3 hub on the board connected to RK3399's USB3 host port (the hub appears twice, once with product ID 0616 -- that's SuperSpeed most people call USB3 -- and once with ID 0610 -- that's Hi-Speed or incorrectly called 'USB2') The JMS561 is behind the internal hub We also have a 7-port Terminus Technology USB2 hub on the PCB One FTDI UART adapter is internally connected to this hub (no idea what's that for -- maybe access to the 'MCU' that can be added to the board?) I then used a 4th SSD in a VIA VL716 enclosure (USB-C) connected to the USB-C port just to end up with the same symptoms I already ran into when testing with USB-C on NanoPC-T4 and RockPro64 a while ago. Tons of error messages in the logs (updated dmesg). In the kernel messages the question 'Maybe the USB cable is bad?' appears and I would believe the kernel is right (I have 2 USB-C cables, the good one from Apple somewhere where I don't find it, the el cheapo providing those messages. I need to buy another one) The good news: there is SuperSpeed (USB3) on the USB-C connector and it's not behind the internal USB3 hub (BTW: Schematics for the board are here: https://dl.vamrs.com/products/ficus/docs/hw/). The bad news: all USB receptacles are behind one of the two internal USB hubs.
     
    So let's focus now on the 2 SATA ports provided by the JMS561.
     
    1) Samsung EVO840 connected to one of the SATA ports. Testing methodology exactly identical as outlined here: https://forum.armbian.com/topic/8097-nanopi-m4-performance-and-consumption-review/?do=findComment&comment=61783. Only some minor slowdowns compared to NanoPi M4 (there the JMS567 USB-to-SATA bridge also being behind an internal USB3 hub). In other words: When HDDs are attached this is just fine since then the HDD is the bottleneck but neither the JMS561 nor the USB3 connection:

    2) Another Samsung added to 2nd 'SATA' port (now 2 disks connected to the JMS561). Running two independent iozone tests with 2GB test size at the same time. As expected we now run into 'shared bandwidth' and bus contention issues since both SSD are connected to the same JMS561 that is bottlenecked by the upstream connection to the SoC (one single SuperSpeed line that has to go through the USB3 hub). If we would talk about HDD the below numbers are still excellent since HDD are still the bottleneck with such a '2 disk' setup.
    random random kB reclen write rewrite read reread read write PM851 2048000 16384 131096 132075 161149 162122 161282 131273 EVO840 2048000 16384 151916 157295 176928 183874 186000 178285 3) Now adding another Samsung SSD in an JMS567 enclosure to one of the USB3 receptacles (also behind the hub). As expected 'shared bandwidth' and bus contention issues matter even more now with 3 parallel iozone benchmarks running on each SSD in parallel. But the newly added Samsung EVO750 in an external enclosure finished way earlier:
    random random kB reclen write rewrite read reread read write PM851 2048000 16384 112897 130875 125697 171855 175661 134626 EVO840 2048000 16384 113541 132846 127664 172124 174311 137836 EVO750 2048000 16384 214842 164890 328764 326065 197740 154398 TL;DR: The 2 available SATA ports provided by a JMS561 in PM fashion are totally sufficient when you want to attach one or two HDDs. In case you need highest random IO or sequential IO performance exceeding the USB3 limit (with this 'behind a hub' topology this means ~365 MB/s) then your only choice is the PCIe slot once it works (either by using a PCIe based SSD there or a SATA or even SAS adapter)

    Another look at the 2 SATA ports provided by the JMS561.
     
    The same IC is inside Hardkernel's Cloudshell 2 thingy where users face serious SMART related issues. So let's do a quick check with an SSD connected to each SATA port:
    root@rock960:~# for i in a b ; do smartctl -d sat -x /dev/sd${i}; smartctl -l devstat /dev/sd${i} -d sat,12; echo -e "\n\n\n\n\n" ; done | curl -F 'f:1=<-' ix.io http://ix.io/1o0p root@rock960:~# dmesg | tail -n5 [ 10.090856] rk_gmac-dwmac fe300000.ethernet eth0: Link is Up - 1Gbps/Full - flow control rx/tx [ 89.067105] xhci-hcd xhci-hcd.7.auto: ERROR Transfer event for disabled endpoint or incorrect stream ring [ 89.067959] xhci-hcd xhci-hcd.7.auto: @000000007bc32a30 00000000 00000000 1b000000 03078001 [ 89.162393] xhci-hcd xhci-hcd.7.auto: ERROR Transfer event for disabled endpoint or incorrect stream ring [ 89.163274] xhci-hcd xhci-hcd.7.auto: @000000007bc32ac0 00000000 00000000 1b000000 03078001 As http://ix.io/1o0p clearly shows the issue is still there. For the disk connected to the 'SATA1' port only bogus SMART data is returned. Shutting down the board, exchanging SATA cables so that now the EVO840 is connected to 'SATA1' and again: SMART readouts broken for the disk connected to this port: http://ix.io/1o0t
     
    I then wanted to create a btrfs mirror to test the same with drives busy but to my surprise Vamrs' kernel has no btrfs support enabled. Then tried an mdraid-1 (which I personally consider the most stupid disk setup ever but hey, it's only about a load test) but also no mdraid support in this kernel
     
    Ok, then continuing with individual ext4 filesystems on each SSD, running iozone -e -I -a -s 20000M -r 16384k -i 0 -i 1 -i 2 on each SSD and then again doing the smartctl queries.  No USB bus resets, performance also not affected but of course still bogus SMART readouts for one SSD and the above xhci error messages in the log.
     
    So both SATA ports still are fine from a performance point of view when combined with HDDs (since all HDDs are that slow that they are the bottleneck and not the JMS561 provided SATA port) but unfortunately there are functional limitations wrt the disk connected to the 'SATA1' port (no SMART health queries, you can start SMART selftests but since SMART status can not be queried no way to get selftest results without exchanging disks/cables).
     
    That being said Ficus with just one HDD connected to the 'SATA2' port is a great combination. I hope Vamrs looks into this, gets in touch with JMicron and checks whether this can be resolved with a firmware update.

    Please be very careful with these wordings. M.2 is not mSATA. M.2 is just a mechanical connector able to transport a bunch of different protocols. In case you have no other device suited for an M.2 SATA SSD you might want to have a look at https://jeyi.aliexpress.com/store/group/USB3-0-USB3-1-Type-C-Series/710516_511630295.html for external USB3 enclosures (to get a bulky but ultra fast 'USB pendrive'). But since a 'generic' 60 GB SSD will perform crappy anyway and you talked about Amazon the best you could do is to return such a thing right now.

    Close to 100 MB/s sequential speed without any more optimizations is simply awesome:

    Nope, everything as expected. The M4 number in the list https://github.com/ThomasKaiser/sbc-bench/blob/master/Results.md has been made with mainline kernel which shows way higher memory bandwidth on RK3399 (check the other RK3399 devices there). Cpuminer numbers differ due to GCC version (Stretch ships with 6.3, Bionic with 7.3 -- see the first three Rock64 numbers with 1400 MHz in the list -- always Stretch but two times with manually built newer GCC versions which significantly improve cpuminer performance)
     
    If you love performance use recent software...

    I did just that:
     

     
    The thick thermal pad has been removed and replaced with a 15x15mm copper shim (0.8mm height). The grey stuff around the SoC are leftovers from another thermal pad (came with RockPro64) just to prevent shorting things with the heatsink.
     
    I tried to use sbc-bench in thermal testing mode. NanoPi Fire is in upright position (so convection might help a little bit) in a room with 24°C ambient temperature.
    sbc-bench.sh -T 80 ; sbc-bench.sh -t 60 Problem N° 1: with stock thermal pad I would have to wait endlessly for the SoC to cool down below 60°C (that what 'sbc-bench.sh -t 60' is supposed to do). The board once hot remained at 62°C to 63°C. I had to temporarely switch cpufreq governor to let the CPU cores clock down from 1400 to 400 MHz to get an idle temperature below 60°C again.
     
    Then numbers were as follows:
    1400 MHz: 146.17 sec 1300 MHz: 148.42 sec 1200 MHz: 0 sec 1100 MHz: 0 sec 1000 MHz: 0 sec 900 MHz: 0 sec 800 MHz: 0 sec 700 MHz: 0 sec 600 MHz: 0 sec 500 MHz: 0 sec 400 MHz: 5.80 sec (the 6 seconds on 400 MHz are not result of throttling but me manually switching back to performance cpufreq governor once the real benchmark run started). Full output where you can see how long it took to cool down from 80°C to 60°C: https://pastebin.com/raw/1DDt8yGk
     
    Now with copper shim instead of thermal pad.
     
    Problem N° 2: now it's impossible for the 'pre-heat' run to get above 80°C. I would have to wait endlessly for this so I stopped and ran 'sbc-bench.sh -T 78 ; sbc-bench.sh -t 60' instead to only wait until temperature exceeds 78°C. Full output: https://pastebin.com/raw/a0vmQJ0b
     
    No throttling happened and temperature remained below 80°C. Again it's obvious that thermal pads simply suck when it's about efficient heat dissipation. But I've to admit that I've no idea whether the contact area now with my copper shim is sufficient or thermal pads are the recommended way since with my copper shim now only the very small die area and the copper shim have contact while the area around not.
     
    @mindee can you please shed some light?
     
    Edit: haha, today I realized that I ran with just 4 CPU cores active yesterday when I made my tests due to 'maxcpus=4' set in /boot/armbianEnv.txt (to test for swap efficiency of various approaches). Doesn't change anything wrt thermal conductivity but of course now with all 8 CPU cores active NanoPi Fire3 starts to throttle severely when running heavy stuff but at least with copper shim clockspeeds are much higher compared to thermal pad.

    tkaiser got a reaction from Werner in Security Alert for Allwinner sun8i (H3/A83T/H8)   
    EDIT: This is NOT about a (hidden) backdoor but just a local privileges escalation that affects one single 3.4 kernel variant for 2 Allwinner SoCs. In case you came here through lurid headlines please read this comment here first and help stop spreading further BS like "all Allwinner devices contain a hidden backdoor" -- the code has been found since Allwinner could be convinced to open their Github repos in the past so everyone is able to audit their Android kernel source!
     
     
     
    It has been brought to our attention two days ago on 2016-04-30 in linux-sunxi IRC that Allwinner's 3.4 legacy kernel for H3/A83T/H8 contains a nasty local privileges escalation. Any process running with any UID can become root easily by simply doing this:
    echo "rootmydevice" > /proc/sunxi_debug/sunxi_debug Combined with networked services that might allow access to /proc this means that this is also a network enabled root exploit. As usual we fixed such an issue within a few hours, on May 1st new Armbian 5.10 images were rolled out and in the meantime the fix is also in Armbian's apt repo so please upgrade now (apt-get update/upgrade or start with a fresh OS image) if you're affected! If you're already running Armbian 5.10 then this vulnerability is already fixed.
     
    This security flaw is currently present in every OS image for H3, A83T or H8 devices that rely on Kernel 3.4: this applies to all OS images available for Orange Pis (except Armbian 5.10 available since May 1st), any for FriendlyARM's NanoPi M1, SinoVoip's M2+ and M3, Cuebietech's Cubietruck + and Linksprite's pcDuino8 Uno
     
    We informed all vendors where possible also two days ago (FriendlyARM and SinoVoip took notice, the others still ignore the issue) FriendlyARM: https://github.com/friendlyarm/h3_lichee/issues/1 SinoVoip M3: https://github.com/BPI-SINOVOIP/BPI-M3-bsp/issues/10 SinoVoip M2+: https://github.com/BPI-SINOVOIP/BPI-M2P-bsp/issues/1 Cubietruck +: https://github.com/cubieboard/Cubietruck_Plus-kernel-source/issues/2 LinkSprite pcDuino8 Uno: https://github.com/pcduino/pcduino8-uno-kernel/issues/3 Users of any of the available OS images for H3 based Orange Pis are somewhat lost since none of the OS images or kernels used for these are maintained any longer. Loboris disappeared (so the opened issue is more like a reference) and Xunlong themselves do not maintain their software at all (not even possible to open an issue there).   In case some readers here do also have accounts at Orange Pi forums, please spread the word and inform the users that their OS images are exploitable unless they already use Armbian 5.10. Same applies to Banana Pi forums, please spread the word there also that all M3 and their M2+ OS images are affected (I deleted my account there since talking to @sinovoip is like talking to a wall and just makes me sick, but it might be worth the efforts to try to warn their users)

I still have no idea why this benchmark on some boards (most probably kernels) runs with 1 GB without swapping but not on others like here:
    RAM size: 994 MB, # CPU hardware threads: 4 RAM usage: 882 MB, # Benchmark threads: 4 NanoPi Fire3 also with just 1 GB RAM finishes with only minimal swapping:
    RAM size: 990 MB, # CPU hardware threads: 8 RAM usage: 901 MB, # Benchmark threads: 8 Maybe vm.swappiness is the culprit. Can you repeat the bench another three times doing the following prior to each run:
    sysctl -w vm.swappiness=0 sysctl -w vm.swappiness=1 sysctl -w vm.swappiness=60

    Exactly same numbers as PineH64 which is not that much of a surprise given same type of memory is used with same settings. Your 7-zip numbers seem to be lower but that's just some background activity trashing the benchmark as the monitoring reveals. If you see %sys and especially %iowait percentage in the monitoring output you know you need to repeat the benchmark and stop as many active processes as possible prior to benchmark execution:
