I tried to turn it on with remote control and also deattached the device a few times... no chance it just says:

 

root@alex-ThinkPad-T510 /home/alex/Downloads > rkdeveloptool rd 3
Reset Device failed!
root@alex-ThinkPad-T510 /home/alex/Downloads > rkdeveloptool rd 3
Reset Device failed!
root@alex-ThinkPad-T510 /home/alex/Downloads > rkdeveloptool rd 3
Reset Device failed!
 

Actually I remember some dark sparks about shorting some point on the board to get into "MASK ROM MODE". Unfortunately I just wrote it into freaktab board and this is unfortunately down now... so maybe you can remember it. I did this already on some other V88 devices with other pcb... so I am not sure if it was just on the devices with eMMC, but I remember some tweezers shorting on the backside if i am right... *f...* that's so long ago...:(

By the way I noticed if you forget SD card the device don't get recognized from PC. It just loads into multitool then. ;)

 

Here are some pictures of my board

I can't remember if the red or blue circle needs to be shorted...

@Alex83 nope, the bootloader was uploaded correctly, it just made some mistakes about some kind on incompatibility or maybe issuing reset garbled the NAND status somehow.

 

As I suggested, repeat the procedure skipping the first rkdeveloptool ef command.

 

If it still does not work, repeat the procedure using the v2.51 and v2.47 loaders.

 

If nothing works yet, the last resort is RkDevTool for windows (formerly known as AndroidTool) you can download from here

Ok, so let's see if I understood:

  • you plug the USB cable
  • lsusb is telling that the device is there
  • if you run rkdeveloptool rd 3 it tells you "Reset Device failed!"

 

If so, believe it or not this is the best condition :)

 

Repeat the procedure starting from upgrade_tool, hope this time works :)

Ahah, no wait a second. I just spotted a mistake in the instructions!

The rkdeveloptool ef is removing again the bootloader you just installed :ph34r: sorry for that... (I'm going to fix them)

 

Let's try again:

  • Unplug the USB cable
  • Plug the USB cable
  • run upgrade_tool
  • Wait for a minute
  • Unplug the USB cable

Then finally it should work as expected

 

edit: going to give you credits on first page if this madness works :D

Hi Jock,

 

actually i did it as you said and it recognises the NAND again. - I just don't know if I did a mistake again because I read somehow something with "NAND Jump" and did this in multitool. - Afterwards I installed as usual Armbian with legacy-Kernel 4.19 to NANA via sTep...

 

Anyway... after finishing the device does not boot. The HDMI output stays black. 

 

I just do a minimal buster installation with 4.19 kernel now and write back in a minute...

 

Maybe if the device works again I can provide you dmesg from armbian there... or I would also provide you serial output, but don't know where to connect via serial. If you find some points, I have also soldering skills ;)

Ok, did it again without the erasing in the end... because the device does not start from NAND installed images unfortunately...

 

I noticed this time the output from "upgrade_tool ..." was very quick and showing "Upgrade loader ok" much faster than before. I waited for 2 minutes after that output.

Edited by Alex83
no luck with booting the device from NAND

About the serial, unfortunately it is not a board I known. I know chiptrip hide the serial pads very well on their boards and I had to ask @fabiobassa (he has much better skills in electronics than me) to find them.

 

Ok, the NAND is back and this is a very good news, now I investigate the issue about the legacy kernel armbian not booting (beware: legacy kernel is 4.4, not 4.19, are you sure you're using the right image?), trying to replicate on my board and will tell you ASAP

Hey! Good news! Luckily the Buster-minimal-image with kernel 4.19 boots up! B)

 

You're the master! I'll reply after finishing booting. - Actually my prefered system is always ubuntu because of some ppa for tvheadend and so on... maybe I'll change later again.

Maybe you meant kernel 4.4? I just finished installing the legacy kernel image (freshly downloaded from here) on NAND and mine also boots fine :D

 

I will be waiting for iperf3 and reboot tests ;)

You're really the rk322x-god! :D

 

 

  Reveal hidden contents

Reboot worked the first time. After I ran rk322x-config I haven't tried, but will reply if reboot is still working then.

 

Unfortunately the wifi-issue is still onging... I need to ping my wanted remote device from V88-box before I can get ssh into it. So that's still very annoying, but guessing it is because of the good ssv6051 chipset...

 

Yes, you are right. I meant of course kernel 4.4

 

I also tried the iperf3-test again and guess!!

FritzBox says the device could connect just with 20 MHz bandwith, that means that maximum data rate is 72 Mbit/s.

 

So in this case 44 Mbit/s is ok in my opinion for now...

 

I use 40 MHz bandwith on my FritzBox7490, but output about rk322x device is here:

  

WLAN-Eigenschaften (2,4 GHz)
Signalstärke-50dBm
max. mögliche Datenrate72 / 72 Mbit/s
aktuelle Datenrate71 / 72 Mbit/s
WLAN-StandardWLAN-b+g+n / Wi-Fi 4
Frequenzband2,4 GHz
Kanalbandbreite20 MHz
Streams1 x 1
WLAN-Eigenschaften
VerschlüsselungWPA2
Signaleigenschaften
QoS (Quality of Service)WMM
Repeaterbetriebnein

So it's connected with it's maximum speed the v88 mini 4k

Very good! I'm very pleased to read that finally we got the best out of the board ;)

The wifi benchmark is excellent for a 72Mbit/s link,I'm not totally sure the chip is able to establish 40 Mhz links, I think it is a single stream chip so that is the maximum you can get from it, but nonetheless it is quite above the benchmarks I did in the past that were around 37Mbit/s.

 

Thanks again for the patience, now I go to put credits on first page and a link to the instructions for people who wants to upgrade the NAND bootloader ;)

Dear all,

I have a few TV boxes, both amlogic and rockchip, and was able to install Armbian on many of them (with lots of blood, sweat and tears... Thanks a lot to Balbes150, Jock and Fabiobassa for all the superb work and the gold nuggets that they left in the various threads!!!).

I am struggling now with a T96mini_V1.0 (  see https://pasteboard.co/JTEA7XS.jpg  - I don't know why I can't insert pic in post...) which has an RK3228A (2G-16G). And has NO sdcard, I followed advice from the 1st post, but black screen...

I want to use it as a headless linux server, so I don't care about media performance, but WIFI would be appreciable (see pic of chip: https://pasteboard.co/JTELgqj.jpg )

OK, so I found the serial console, soldered some wires, and saw  a boot entirely in chinese... so no cues about dtb. I still have an android image that boots ok, so maybe I could extract DTB?.

(Very) long story short, I was able to burn multitlool in emmc, and boot either from usb or emmc, but I get kernel panics every time (see below). I suspect that I have a wrong DTB, which does bad things...

Here is the boot log, using a toothpick to boot the multitool image from usb:

 

  Reveal hidden contents

 

When booting from emmc, most of the time I have nothing after "Booting kernel, and sometimes some kernel traps.

 

Any suggestions or pointers?

 

Cheers,

 

Michel

Ciao Michel, welcome in this valley of tears lol lol lol
Well, another lovely board with no SD reader and this makes the whole story a bit complicated , but not impossible to solve.
Ant thank you so much for photos and serial uart log, this really helps

The kernel as you can see is starting and the kernel panic could be for wrong trust_os, wrong dtb, not mounting the root fs ,one only or all 3 causes lol
If you have original firmware you can extract the pieces and in particular dtb with this tool 

RK3xxx_firmware_tools_5.23.1_by_SergioPoverony.zip


(google for it ) but I guess you have nothing of different from other boards with ddr3 and emmc

Let's wait @jock for further infos on how to approach at this rare study case but I can say to you for sure that it will boot

You are new so cannot post many posts in the first days , you must wait I believe one day for other post.
And don't forget to click a " like" ( the heart icon) for helping good reputation of authors
Where are you from if I can ask , and have you some skills on linux so it will be in some manner easier?

 

EDIT:

I attached a command line CLI only windows tool to extract pieces from a firmware , try it please

@gurzixo hello. Yes, your board is doing absolutely weird things.

This is a rare situation I yet have to understand why it happens. I have a board with rk3228a that runs for days without any issue on legacy 4.4 kernel, but crashes immediately with messages similar to yours if I use the mainline kernel.

I tried almost everything I could think about on that board to solve or at least mitigate the issue, but with no success.

 

If you could extract the DTB, it would very helpful for clues that may explain what is happening.

The multitool DTB is a very basic DTB that should work on all boards, it is designed to be very compatible and usually works on most boards without complaints; the only testing thing I can imagine is to disable the vdd_log and vdd_arm regulators and removing/disabling the cpu operating frequency table to avoid frequency scaling.

 

I already did such experiments on my rk3228a board, but it did not improve stability at all, suggesting the issue is probably elsewhere.

Thank you very much to both of you!

 

Unfortunately even if I use now the Ethernet Interface instead of wifi there are constantly Kernel Panic Informations;

Would you mind to help me to get TVHeadend 4.3 (unstable) to work on this device? I need it for armhf architecture and can't find any good resource. Only for Ubuntu Focal there are Repositories and the reson why I usually use Ubuntu. Unfortunately there is no minimal Image for Ubuntu and that's why I installed Buster image.

@Alex83
tell me if I am correct : will You  use a tv dongle to receive dtt tv ?
what is for tvheadend ???

I guess you want use it for this purpose ... I did some experiments to receive DAB and DMR radios on a 322x and..... well hope your  project will be functional, mine was not :unsure: :wacko:

Hi, 

 

I already use it with focal images on my Banana PI, but wanted to replace it to 322x. I don't know why the paic appears it seems like this always happens if a lot of data get extracted, but the RAM shouldn't overflow. I start wie 100MB of 1GB RAM usage and pull around 200 MB. So it shouldn't be full and the panic happens on diffrent stages of pulling.

@Alex83 I have no experience with tvheadend, I don't even know what it is. It looks to me that the error is somehow related to bad architecture.

Try to post a question in the general chit chat forum on how to compile it for armhf if it is your necessity.

But @Alex83 you still continue to compare things lol lol

maybe the one for banana pi is compiled with flags for banana pi, the error you have is may be and i say maybe related to things that tries to download and it doesn't find on repository since even if are both ARM may be some processor instructions are not the same.

I told you, you want to port on this box things made for other box: of course you will get it but be ready to tears and blood
And as @jock said it seems more a problem of architecture and compatibility than a kernel related problem

have you tried apt update && apt install tvheadend  maybe are in official repository ?

Hey guys,

 

thank you very much for your replies! I don't wanna continue off-topic discussions even if I would love to discuss with you longer. ;) But just a hint that in armbian-config menue there is a Point for "Softy" and there you can directly install Tvheadend. Unfortunately it is stable release, that means Version 4.2 and I wanted to try unstable 4.3. There is a possibility for transcoding via VAAPI and hoped maybe it works since VAAPI should work with that devices, don't they?

Uhm... I don't know the state of VA-API for hardware decoding and encoding with rockchip on legacy kernel. Maybe there's a driver and it works, but surely there is nothing already cooked for that. The media script pointed in the first page does not install any va-api driver (it installs rkmpp, 3d support via armsoc + mali drivers, kodi and ffmpeg), and I don't know if there is some kind of wrapper to do so, but I guess not.

On mainline kernel, things are materializing right now, but it is still too early for va-api support - it is not yet planned AFAIK.

Hey guys, 

 

don't wanna bother you, but independent of my tvheadend topic there appear more and more storage errors like the ones I posted... Any ideas what could be wrong? The device looses it's accessability also then...

and conside mine is emmc of 16 gb.
Which kind of errors do you believe have ???

And if it loose accessibility is because this thing you are trying to download/install goes in wrong places and/or break something in booting process
Anyway in my little opinion is you want to give a try it should be this:

https://github.com/orgs/linuxserver/packages/container/tvheadend/1613987

this is for arm7 32 bit
But if you encounter problems I will not go to answer you since this is a more specific question and not a general problem of board

Hey, thanks for your answer @fabiobassa!

 

As I said I use now the offer of "Softy" in armbian-config. This includes also Tvheadend Version 4.2.

 

I also noticed if I limit the maximum CPU speed to the second highest then the box becomes more stable and haven't seen an error like in my above post yet. The device works overnight already without errors. 

 

I also noticed that wifi issue is still ongoing and TX performance is usually worse than RX even when it's connected with full speed (72 Mbit/s up and down @50dBm).

 

Well it seems like I need to cut my speed @1,3GHz for the box unfortunately...

 

I noticed that CPU usage is showing often more than 100% on one process. This is still a bit confusing for me, but I think even when there are 4 cores shown in htop maybe it's handling is different than the boxes I know ( * pi series) with this topic. The speed on the right side is just shown once the CPU speed of 1,3GHz and in *pi boxes you see the speed 4 times and no single process is shown >100% CPU load. 

 

But I will now test a bit around and give you feedback about the stability. 

 

Thanks a lot for now!

rk322x-config sets the maximum cpu frequency to 1.2Ghz in case you have an rk3228a because it is their rated speed. Maybe your board has a rk3228a but you choose rk3228b or rk3229.

About wifi performance, it is perfectly normal that TX and RX performance differs. Usually TX is a bit higher than RX, but that depends a lot on the setup and the connected devices.

If a process is using more than 100% of the cpu (I guess you mean using top or htop) it means that the process is using more than one core. This is perfectly normal although.

The only issue with legacy 4.4 kernel is the load average, which has its baseline at 4.00: that's a bug, because the baseline should be 0.00.

Thanks to all of you for your kind words! I also forget to thank all the other who helped ;)

 

FYI I am French, 62, living now in Portugal, *soldered* my first computer (a Z80 Nascom ;) ) at 19, and I have a good experience in embedded systems, electronics, network and system programming on various OSes.

 

@fabiobassa @Jock :

I tried to extract the dtb using PabloCastellano's extract_dtb.py, but it gave weird things. Thanks for your tool (I work on Linux and there was also a Linux version!). Using it with 2nd level decoding, and then using linux's dtc on Image/resource.img.dump/rk-kernel.dtb for my working android image gave:

  Reveal hidden contents

 

But before taking the dtb route, I would like to fully reprogram this board from scratch, as I am sure that I did some mistakes somewhere.

especially: 

GPT 0x63337df8 signature is wrong
recovery gpt...
GPT 0x63337df8 signature is wrong
recovery gpt fail!

At the beginning of the boot seems very bad!

 

I am new to those boards, knowing nothing from them 2 weeks ago, and the information is scattered in lots of places (is there a WIKI somewhere, as it is BADLY needed?), so this is what I understood:

  • The RK322X chips are done by Rockchip which assembles IP blocs licenced by ARM to make a SoC. ARM and the communauty provides compilers, linkers and the like.
  • The box is intended by Rockchip to run under Android, and Rockchip tools are heavily biaised toward this environnement, with a lot of specific tools, and an old kernel (3.x and maybe 4.x).
  • Armbian is a Debian distribution, adapted to run on Arm chips, which makes for a very diverse ecosystem, and follows the Linux track (new kernels, etc). Both environments do the same job, but there are many places where armbian and rk/android tools are not compatible.
  • The box has a (set of) processors, RAM and flash plus various peripherals, some of them being integrated in the SoC. The flash can be Nand, or eMMC (which is nand plus a controller taking care of many details, including bad blocks and wear levelling). As seen from the software, flash is a linear vector of blocks (of typically 512K each) which can be R/W with only this granularity. All of them have a (usually hidden) serial line, that runs @ 115200 bauds, and gives lots of system information.
  • Putting Linux on this box consists in reprogramming fully the flash, and this is done using an *image* (extension ".img"). It can be flashed using RK tools (rkdeveloptool for linux) directly on the chip through USB, or by crafting an sdCard which will do the job.
  • The RK322X has 2 reset modes:
    • Loader mode which allows only access to flash above 0x2000*0x200
    • maskrom mode which allows for full access. The chip enters maskrom mode when it cannot read flash; that can be accomplished  in a wild way by shorting pins 8 and 9 of the eMMC chip at boot (which is why RK322X chips are nearly unbrickable)
  • The boot sequence is complex:
    • Execution starts first with a miniloader (? at a certain offset in flash?) whose job is to load a 2nd level loader (?located at another offset in flash?) called u-boot.
    • U-boot is based on Das U-Boot modified by many people. All of them are more or less compatible, with subtle differences. They have one thing in common, which is that a ^C on the serial line stops the boot and gives a CLI. The Job of uboot is to load the Linux kernel in memory, and start it using a command line with various parameters.
    • One important parameter is the DTB, which indicates to the kernel (drivers) the hardware details. This is a binary blob (.dtb) compiled from various source modules (.dts). The armbian and android dtb are similar but not compatible. They can be decompiled by (mostly uncompatible) compilers (dtc in linux).
    • Another important parameter is the offset in flash of various filesystems.
    • Then he kernel starts...
  • An image is the concatenation of various blobs according to a certain format. Armbian and RK images are NOT compatible, as they don't have the same numbers and type of blobs, and so require different sets of tools (?which ones?)
  • Is the 1st-level loader (?located at offset 0 in flash?) part of the armbian image

So, in order in order to *fully* reflash my box:

  1. Manage to enter maskrom
  2. rkdeveloptool db rk322x_loader.bin
  3. rkdeveloptool ul rk322x_loader.bin
  4. rkdeveloptool wl 0 multitool.img

Am I right or should I have missed something?

@gurzixo
hello Michel , yes to ALL your questions except for
 

  Quote

maskrom mode which allows for full access

Expand  

 

this is true for emmc. For nand since them charateristic the discussion is little little different, but let's assume is quite the same for our purpose:
It is good idea and safe approach DON'T TOUCH idbloader , the very very very first stage of loading something in ram and go modify starting from address 2000
Will follow a different approach for your board so please be patient some hours so i can give you more details
EDIT :

  Quote

or by crafting an sdCard which will do the job

Expand  

  this also is half half correct: the sd card will do the job if there is a uboot and a trust ALSO in sd card at right places . It will happena " jump" from the internal uboot to sd uboot and then continue bootng from sd.
But don't worry we wil go back from scratch

I have a couple of questions:

- Is this storage map the one used by android, multitool, legacy and up-to-date armbian, or are they each using different maps?

- I found very few information about the GPT partition table, what to put inside and how to build the parameter_gpt.txt  file used by rkdeveloptool. Are there some pointers available?

 

I have also a strange thing: I am able to enter loader mode by wiping emmc, and everything works well (ie. test chip, read id, etc.). But when I enter maskrom mode, I have the correct PID/VID on USB, but all rkdevelop commands block (ie I have to press ^C to come back to shell).

This is the case either when I reboot by software (rkdevelop rd 3) or by hardware (ie. short emmc pins)

And when I reload multitool in emmc, it still gives kernel panic.

strange...
