RAS Error in L2 on BL31 and failed to boot when Xavier NX boot up

WakkeWang · January 3, 2023, 3:13am

Hello, team, I am testing the cold boot on Jetson Xavier NX emmc module(Jetson Linux Release 35.1), Power on the module for 90 seconds, then power off for 30 seconds, and then repeat the cycle continuously.

I have tested more than 3000 times, but found two times failed to boot. Here are the boot logs:

failed_to_boot.txt (21.3 KB)
failed_to_boot-2.txt (105.2 KB)
normal_boot.txt (97.3 KB)

please help me to solve this, thanks!

Why did you tell me you are using 32.7.2 but showed me a rel-35 log?

WakkeWang · January 3, 2023, 7:58am

Sorry about this , I am using R35.1

WayneWWW · January 3, 2023, 7:58am

Is this tested on custom board or devkit?

WakkeWang · January 3, 2023, 8:04am

Jetson Xavier NX emmc module + custom carrier board

Could you change tos-trusty_t194.img to tos-mon-only_t194.img in below file and try again?

p2972-0000.conf.common

WakkeWang · January 4, 2023, 8:49am

In my p2972-0000.conf.common :

TOSFILE=“bootloader/tos_t194.img”; not tos-trusty_t194.img

Now I change tos_t194.img to tos-mon-only_t194.img ?

Check the exact file name under your bootloader folder. And change it to the one with “mon-only” string inside of it.

WakkeWang · January 4, 2023, 9:00am

OK , I will test again , here is my setting after modifying p2972-0000.conf.common

WakkeWang · January 5, 2023, 11:03am

I modified p3668.conf.common instead of p2972-0000.conf.common.

root@yzj-ThinkPad-E460:/mnt/R35.1/OK/1_STEP_EMMC/Linux_for_Tegra# cat p3668.conf.common | grep TOS
TOSFILE="bootloader/tos-mon-only_t194.img";

but I failed to flash the xavier nx modules, here is the logs:

On PC :
./flash.sh -r jetson-xavier-nx-devkit-emmc mmcblk0p1
flash_log.txt (52.5 KB)

Xavier nx log:
xavier_nx_log.txt (6.7 KB)

please help me to flash the module , thanks

Hi WakkeWang,

Please try again with full flash.
$ sudo ./flash.sh jetson-xavier-nx-devkit-emmc mmcblk0p1

WakkeWang · January 9, 2023, 10:57am

Hi WakkeWang,

Are you connect one Jetson device?
Please make sure you only connect one Jetson device on host PC.

In p2972-0000.conf.common:
TOSFILE=“bootloader/tos-mon-only_t194.img";
Set soft links:
cd .../Linux_For_Tegra/bootloader
ln -sf tos-mon-only_t194.img tos_t194.img
Full flash:
$ sudo ./flash.sh jetson-xavier-nx-devkit-emmc mmcblk0p1

please help me to flash it with tos-mon-only_t194.img

WayneWWW · January 10, 2023, 7:13am

Could you try with nv devkit first?

WakkeWang · January 10, 2023, 7:25am

I try to flash the module with nv devkit , the same error.

WayneWWW · January 10, 2023, 7:26am

Let us check this. Thanks for reporting issue.
