A95X -R1 / S905W issue

Help & Support Installation & Booting
1

Hello,

I’ve just received an A95X-R1 box (with S905W) with 1GB.

I managed to force the boot on sdcard (swith at the bottom of jack port).

But impossible to boot libreelec: either black screen after A95X logo, or boot loop after the same logo.

I tried LE 8.2.3 an CE 8.90.2.

I also tried the following DTB files : p281_1g_xxx and p212_1g_xxx

The motherboard is marked A95XA1_V2_0 / 20170905

The internal case is marked A95MINI 8139.

Any idea how to fix this please ?

Where did you get CE 8.90.3?

4

My mistake : CE 8.90.2

5

Can you look at the CPU on the motherboard and see what it says on it because there is 2 revisions of this device and I fear you may have bought the Rockchip version instead of the Amlogic version.

6

Even worse it will more than likely be a RK3229.
Current LE testing is being done on RK3328 and RK3288 with no testing on the low spec RK3229 .
Send it back or refund.

thanks for your answer, but under Android, it says Amlogic / Cortex A53 with CpuZ (vs Coretx A7 for RK3229), and the specs seems to match.

and you are right, It seems there 2 variants of the A95X R1 : s905W / rk3229

I think I tried the “gxl_p212_1g.dtb”, but I’ll try again to be sure.

I’ll try the refund if I really can’t install any ELEC on it.

Have a look at the firmware version in System Android.
See what firmware the box reads.
The name of the firmware might help.

Here are intel I gathered :

EDIT: 1 more with the back

10

Can you please disclose in detail.
Brand of sd card and full specs.
This may be your issue.
Edit: Use Amlogic Burning Tool and if the box is recognised you will know it’s an Amlogic Chip

11

I’m afraid this is what happens when you buy the cheapest device available on gearbest rather than one that is known to work and supported, I hope this will be a lesson to others.

Can you provide a copy of the original DTB from Android as well?

There are actually 3 when i googled. There is an s905x as well.
This box is a nightmare under that name.
Freaktab have posts with this All sorts Mixed Chips Model.

SD Card : Samsung 16GB, verified after wirting / ok, working on many other S805/S905 devices.

Amlogic Burning Tool : Connect succes !

14

For the DTB, I don’t remember how to do that without the stock ROM in img file, but I’ll search :wink:

EDIT : I searched, but I didn’t find anything good. I have network adb with root access working. any idea/help ?

ok, with ADB, I copie boot.img with
dd if=/dev/block/boot of=/sdcard/boot.img

but the split with a 0 byte for ‘second’ (which should contain the dtb if I am right) :
./split_bootimg.pl /storage_main/tmp/boot.img
Page size: 2048 (0x00000800)
Kernel size: 7110087 (0x006c7dc7)
Ramdisk size: 1315813 (0x001413e5)
Second size: 0 (0x00000000)
Board name:
Command line: buildvariant=userdebug
Writing boot.img-kernel … complete.
Writing boot.img-ramdisk.gz … complete.

stuck …

EDIT 2 : pastebin of dmesg
https://pastebin.com/61DLLZ6D

EDIT 3 :
damned ! I finally managed to extract the dts file !
I found the infos here :


it’s a multi DTB.

here is the start :
model = “Amlogic”;
compatible = “amlogic, Gxbb”;
amlogic-dt-id = “gxl_p212_1g”;
interrupt-parent = <0x1>;

p212 … lol.

EDIT 4:
still not booting with the extracted DTB !!!
here is everything I extracted :

tried gxl_p212_1g.dtb : NOK :frowning:

16

I managed to flash the MMC with TX3 mini dualboot.
It works ! I can boot on LE

I tried many other firmware, none accept to boost on SD.
I tried sandisk and samsung sdcard. Same result.
I tried USB flash drive. Same result (stuck at boot or bootloop).

The main issue now.
Libreelec version doesn’t work very well (frame drops).
I updated it to CE 8.90.2.
It works much better … but I don’t have the remote anymore :frowning:

I tried to update the remote.conf.
no working.

I tried changin the DTB to :

  • gxl_p212_1g.dtb => boot, no remote
  • gxl_p281_1g.dtb => boot, no remote
  • gxl_p281_1g_a95xr2.dtb => boot, no remote
  • original TX3 mini (which worked with previous LE) => boot, no remote

I used this process to update to CE :

EDIT : oh yes.
I can see key logs in dmesg :

[ 473.777725@0] remote: Wrong custom code is 0xf10e4040
[ 474.040207@0] remote: Wrong custom code is 0xf10e4040
[ 474.355932@0] remote: Wrong custom code is 0xf10e4040

the /storage/.config/remote.conf

factory_code = 0x40400001
work_mode = 0
repeat_enable = 1
repeat_delay = 130
repeat_peroid = 120
release_delay = 20
debug_enable = 1
…

Glad you got the box to boot. But please read/search before making posts… This is not new information.

I also did that (search and copy keymaps.rc and co) :stuck_out_tongue:

$ ir-keytable -t
No devices found

The meson drivers seems to load as a keyboard or something like that.

thanks for your help :stuck_out_tongue:

19

one thing I really don’t undersant :
the remote.conf isn’t used anymore ?

why those “remote: Wrong custom code is 0xf10e4040” if the remote.conf is correct ?

20

remote.conf isn’t used anymore.

21

ah ok !!!
now, it’s clear :stuck_out_tongue:
thanks.

any idea how to fix my issue ?
