Armbian for Amlogic S9xxx kernel 4.1x (>= ver 5.55)

Recommended Posts

@balbes150

Hello Oleg, I have downloaded file KM8P-MHC19J-20170224.165245.V0923.img  from 4pda thread on Km8-P ( http://4pda.ru/forum/index.php?showtopic=807465 ) , is there any way I could extract the u-boot binary from that image file and put it on an SD card using your previous instructions? Or do you suggest I try another u-boot binary ? Thank you for your help. :)

 

 

Edit: I have answered my own question by following the instructions on this page: https://www.cnx-software.com/2016/11/19/how-to-create-a-bootable-recovery-sd-card-for-amlogic-tv-boxes/

 

and after rebooting with the card with the u-boot from the image file linked above, IT WORKS! :beer:

 

Here is the dmesg first few lines:

Conclusion: Oleg, you are a genius, it was exactly the u-boot in my Km8-P original firmware that was preventing booting a 4.xx kernel.

Can you show the full startup log of the new kernel (along with messages from u-boot) ?

Sure, here it is attached. Note that I had to interrupt u-boot and manually load zImage etc and then booti, otherwise it was looping because of different env settings. I still have to reboot this box, enter proper env setting, and save them.

 

The main difference I see is in the handling of the DRAM. The frequency tested is 768MHz in this case.

Have you tried to write to eMMC the firmware from which you took this u-boot ? Perhaps with it the kernel 4 \ 5 will be able to be started.

I haven't tried it yet, I was actually thinking about flashing your Armbian image with kernel 4.20 directly onto the internal eMMC once I have determined working and safe u-boot env settings, since I don't really need Android on these boxes.

Wait a bit, I am now building a new u-boot and it is advisable to test it on your model.

Now found one feature of. I recorded the last images for S905 to Sd card, changed in DTB settings (file /boot/extlinux/extlinux.conf) for VIM2 (S912) and checked the startup on S912 (without u-boot in eMMC). The system starts with the use of u-boot for VIM1 at S912. And in the console I saw this information. Ie checked all versions of DDR. Try the same version of the kernel startup 4\5 (image from S905 there is another u-boot).

OK, I am downloading the Armbian image now and will report on how it works asap.

I uploaded a test image 5.76 NEXT with kernel 5 (for a quick check of u-boot) to the site. USB does not work in this image. Just downloaded two deb package with uboot (unzip them and use to write to the SD card files u-boot.bin). I checked another NEXT image from the 5.73 directory with the addition to the SD card after burning the image, u-boot.bin from DEB package for S905. The system starts normally and can be controlled via USB keyboard, but there is no wired network.

Completed tests:

 

1. Previous u-boot (from file s905x-uboot.img in Armbian 5.75 image) Image Armbian_5.76_Aml-s905_Ubuntu_bionic_next_5.0.0-rc7-next-20190219-g43dc36c94-dirty.img.xz boots fine on Km8-P (S912) with 1Gb RAM. Ethernet (wired) works erratically. USB does NOT work (kernel or dtb issue?)

 

(Edit)

2. u-boot.bin from deb package for S905: Image Armbian_5.76_Aml-s905_Ubuntu_bionic_next_5.0.0-rc7-next-20190219-g43dc36c94-dirty.img.xz boots BUT there is a kernel panic before prompt is reached (perhaps too tight memory timings?).

 

(Edit)

3. u-boot.bin from deb package for S912: does not boot. Error is in u-boot RAM detection, as before:

Tested the Armbian_5.76_Aml-s905_Ubuntu_bionic_next_5.0.0-rc7-next-20190219-g43dc36c94-dirty on MXQ Pro + 4k >(S905x), boots fine but USB does not work so unable to log in.

Yes, the WiFi module in the Km8-P uses a S9082 chip for which there is no source code for any Linux kernel, we just have the .ko module built for the Amlogic 3.14.29 kernel as distributed by hardware vendors that use this module, this is why some xxxxelec images are shipped with this module and provide WiFi, but any Linux image with a kernel other than the original Amlogic 3.14.29 won't - including of course any Armbian image.

After reopening my box (m8s pro/s912x-3g)  the wifi  chip is an ltm8830  (it appears to be same as in the T95z ?) there are some threads on it, I'll follow up on those.

 

As for the Ethernet, there is absolutely no joy with any of the dtb's. (tried all the gxm,gxl )  the one thing that 'tickles' me is that upon boot,(prior/during the uboot process)  it shows the following:

...
 size: 0
Net:   eth-1: ethernet@c9410000
Hit any key to stop autoboot:  1 nux/extlinux.conf
....

Does it mean that's using physical interface #1 ? (instead of 0)  ..again, there are some threads that indicate that's the case for the T95z .... 

guess I'll try making /changing the dtd.img and try..

 

On Another issue, after updating the u-boot.img to 2018's,  I seem to no longer be able to boot 3.14 (?) perhaps i need a different version of u-boot.img for 3.14? 

or are there special flags to be passed ? (even tried to manually fatload/booti known-to-work files and it freezes )

 

Thanks for any relevant info/pointers.

C.

Try  test. :) Write to eMMC the standard firmware from which you took u-boot. And after that, check the standard option-activate multi-boot and try to run Armbian (with 4.20 kernel) as usual from external media.

Running the kernel 3.14 is possible, but requires other scripts and settings at startup. To run Armbian in u-boot-2018, use the settings file /boot/extlinux/extlinux.conf

I was thinking: My Android (7.1.2) for MXQ Pro+ 4k runs on a Linux 3.14.29 kernel, that's the Linux part (and why the correct name for Ubuntu, Debian etc. is GNU/Linux).

The Android image is pre-rooted so I have access to all parts of the system in theory. What if I just copy the missing GNU components from another 3.14.29 GNU/Linux into the proper directories and purge the Android specific stuff, will I get a running system? The kernel has support for all HW in the box, yes some modules I will have to keep, but if I just copy and not overwrite anything I should get a working GNU/Linux?

What do you guys think, am I missing something essential here?

I was thinking about doing exactly that for an A95Xpro (runs kernel 4.9.xx)  the issue i've run into is the reconfiguration of the Initrd (can't seem find a way to decompress it, which seems to be required to replace init ) 

Really interested in the answer.

The answer is simple-a waste of time. Details can be found on the Internet on request, what is the difference between Android and Linux systems.

It may be a waste of time, however in the case of the s905X2, all the proper drivers are already configured (granted,it's the old/buggy 4.9.xx) which helps in quickly setting up a  linux mini-server. (mqtt,lamp,mysql, node-red, etc etc etc.  )

 

As for android, if I could completely replace/remove it from most of my arm boxes I'd be a very happy man ! (try to setup an apache server under android's !)

Interesting, I'll have a look into the initrd issue and see what I can find.

Yes, all of them use gzip/lz etc. to decompress the initrd file, but on the files that i've tried all of them seem to be compressed with somthing else (file initrd just answer with 'data'  and cpio just can't decode it. ) it is entirely possible that the file is both compressed and encrypted. (actually, quite possible)  it does not appear to be an ramfs file either (at least, not a standard one. compressed or not)

 

I seem to be able to get the kernel image fine (abooting) and a second file too, but can't decode the resulting initrd/ramfs.

I see, was this Android 8? I'll do some more digging then. I will test with android 6 and 7 and see what I can find out.

yes, 8.1, I did a lengthy search, and aside from a (4.4/kitkat, 7ci cheapo tablet) trick where the actual initrd file had a header of about 70bytes of garbage, I've found nothing.   (tried doing a dump/analysis of the file to see if I could find an gzip/lz/xz etc. header within the file, but without results :-( 

 

The only idea that came to mind, was to re-create a similar version of the kernel/init etc, and import the modules from the android setup (i.e cp the /lib/modules) to ease into a clean setup. (at that point, it may be easier just to find and recompile the whole thing! )

If you could find the source, but I doubt you will. Even cheap China tablet makers holds the source propietary so the only source you will find is open source, and then the HW support is probably not so good so point lost. I don't have any Android build on kernel 4 so can't investigate that.

According to Stackexcange the following compression is supported:


usr/Kconfig:134:config INITRAMFS_COMPRESSION_NONE

usr/Kconfig:145:config INITRAMFS_COMPRESSION_GZIP

usr/Kconfig:155:config INITRAMFS_COMPRESSION_BZIP2
