    barish reacted to jock in ArmbianEnv.txt file being overwritten   
    I experienced this issue tons of times in the past while working on tvbox support, mostly it was happening after freeze/reboot during kernel boot.
     
    As far as I can remember I took a look and there was an armbian service which was rewriting armbianEnv.txt at startup (maybe to update usb quirks?), in fact the order of keys in armbianEnv.txt sometimes changes.
    I suspect that when, for a reason or another, the cache is not correctly wrote to flash, armbianEnv.txt gets corrupted.
    Recently it didn't happen anymore to me, to be honest.

    Most of the files in /etc/logrotate.d are also corrupted with only 'alternatives' seemingly intact.

    Many have streams of  \00\00\00\00\00\ ... appended and many are truncated.
     
    There is an empty file named 'sedd3SIEh'.

    'apport' has been overwritten with the missing part of armbianEnv.txt as follows:

    Hi,
    You can try the following to get an idea of which process is modifying the file:
     
    sudo apt-get install auditd sudo auditctl -w /boot/armbianEnv.txt -p wa sudo tail -F /var/log/audit/audit.log

    It honestly sounds a bit more like a filesystem that has lost track or a inode mixup somewhere? As someone mentioned, perhaps something else is writing to this file, thinking it is something else? Perhaps try to locate a symbolic (or hard)link to armbanEnv.txt:
    ## find any symbolic links to armbianEnv.txt sudo find / -xdev -type l -ls | egrep -i -- armbianEnv.txt ## find hardlinks to armbianEnv.txt - need to be on the same filesystem! sudo find / -xdev -samefile /boot/armbianEnv.txt

    Well, External Abort means that CPU tried to access memory on the bus (not internal CPU memory) and for some reason access (read or write) cannot be completed and it raised exception. Overheating may cause different issues and if some block on SoC stops working then abort may happen.
     
    From your log can be seen that base VDD voltage for 1.2 GHz CPU frequency is set to 1.202 V. Typical voltage for 1.2 GHz freq is documented by Marvell as 1.155 V. Higher voltage value makes CPU more stable, but also increase power usage and temperature. And of course higher temperature make CPU less stable.
     
    During testing 1 GHz mode when CPU voltage was too low I saw lot of times either this External Abort or segfault of random processes. So External Abort can be definitely caused by instability of CPU. But in your case it may be because of either high temperature or low voltage or something else... Also it may be because your SoC/CPU tested during manufactoring and checked that is not really stable for 1.2 GHz freq (and so written this information into OTP -- not defined VDD value for 1.2 GHz).

    This backtrace is from debug version of Trusted Firmware. If you compile it without DEBUG=1 then backtrace is omitted.
     
    A3720 SoC does not have full power management like ATX on PC, which can turn power off from all components. This is why function a3700_system_off() in Trusted Firmware is not implemented.
     
    Basically I just do not know what this a3700_system_off() should do (if I decide to implement it). It can just call reset or maybe call suspend procedure. A3720 has support for some kind of low power suspend/sleep mode, so maybe this is the best approximation of whole power off.

    There is just information that External Abort happened. Not sure what is the issue.
     
    Check that you have kernel with v3 version of a3720 cpufreq patches as in v3 was updated VDD value for load L1 when base freq is 1.2 GHz.
     
    Also can apply updated cpu_vdd_fallback.patch patch? It does not change behavior, only fixes printf for SVC REV: line. But it can can be useful to verify which CPU VDD value is used.

    Despite of all the seemingly bad news, I boldly ordered a batch of 10 EspressoBin V7 recently. Globalscale promised to test them for me for stability (I am not interested in squeezing out the last bit of performance), and I tested them again after reception: They all seem to run stable with Ubuntu Xenial (the "newest" image provided by Globalscale) and with Armbian kernel 4.19.59-mvebu64.
    Since there is still a few weeks till they go on duty, if anyone is interested in a particular test on them, I am willing to do so. I am not into kernel development, so I would need some instruction. ;-)

    Indeed, the configuration in the mvebu64.conf script is wrong.
     
    The 2 CS 2 GB image is compiled with the same DDR topology parameter as the 2 CS 1 GB image (DDR_TOPOLOGY=2).
    It appears that the configuration for the 2 CS 512 MB version is also wrong, as it points to the same topology file as the 1 CS version.
    I guess this is not really a problem, because I'm not even sure that this variant actually exists.
     
    So to answer my previous question:
    What is used is only 512 MB from each chip.
     
    If anyone needs it, here is the bootloader (U-Boot 2018.03-18.12) compiled with the correct topology (DDR_TOPOLOGY=7):
    flash-image-ddr3-2g-2cs-1000_800.bin
     
    Note that only changing the DDR_TOPOLOGY from 2 to 7 was not enough, because this configuration is also missing from the Marvell sources, even though that's the parameter used in the build examples.
    The correct topology exists in the Armbian tree, but with the wrong name:
    https://github.com/armbian/build/blob/master/packages/blobs/espressobin/DDR_TOPOLOGY_2-2g.txt
    The A3700-utils-marvell/script/buildtim.sh script must also be adapted to accept a DDR_TOPOLOGY value higher than 6.

    Well I've fixed my instability issue. The root cause was the same as https://forum.netgate.com/topic/144636/sg-1100-intermittent-reboots, and it was power related. The fix was to replace the 470uf/16V capacitor (component EC1 on the schematic) sat immediately behind the 12V DC jack which under testing leaked under certain temperature conditions (variations). As such the board is now stable and has been running OpenWRT 18.06.2 for 24 hours with memtester and stress running continuous during that entire time.
     
    I'll leave it a few more days, after that I'm going to assume that its fixed and that is what NetGate were referring too when they mention 'a power related component'.
     
    And GlobalScape will not tell you, they know of the problem, in a reply from Kevin Liu he says 'Yes, I do have knowledge regards the power related component issue.' when I asked which component it was so i could attempt to replace myself.

    barish reacted to mu-b in How to make ESPRESSObin v7 stable?   
    I've been looking at something relating to this, recompiling and modifying atf/A3700-marvell-utils to build a viable u-boot. From what I've figure out already, it seems the voltage (VDD) applied by marvell is too low by default.
     
    Does anyone have any visibility on where the modification to ddr4-*cs-/*g.txt from http://wiki.espressobin.net/tiki-download_file.php?fileId=216 came from? namely the following line:
    +;Step9: DDRPHY Driver/Receiver & DQS internal Pullup/Pulldown settings
    +;WRITE: 0xC0001004 0xD0133449
    +WRITE: 0xC0001004 0xD0677449
     
    That is the only difference between the Espressobin provided ddr init and the mainline Marvell A3700 ddr init code.
    At the moment I'm running an Espressobin v7 1000/800 using WTMI-devel-18.12.1-e6bb176 / 2018.03-devel-18.12.3-gc9aa92ce70 with a modification to bump the AVS voltage from 1.032V to 1.155V by default. This is looking to be more stable currently..
     
    If anyone wants the resulting builds let me know. I cannot use the latest https://dl.armbian.com/espressobin/u-boot/ provided versions of WTMI-devel-18.12.1-e6bb176 since it randomly fails to boot. I rebuilt and enabled debugging and so far no stalls.
