Hi All,

Andreas Dannenberg

We are able to bring up the kernel. But we are facing reboot issue..

Steps tried,

1. u-boot 2021 and kernel (TISDK 8.2) and RFS (TISDK 2017.10) booting success there was no observation of rebooting controller..

2. u-boot 2023 and kernel (TISDK 9.1) and RFS (TISDK 2017.10) booting success there was no observation of rebooting controller.

3. u-boot 2023 and kernel (TISDK 9.1) and RFS (TISDK 8.2) rebooting continuously even though i have enable watchdog

Below is the log..

please help on this,

You can see controller is rebooting after ethernet link is up and ready

Also 2 more observation made

1. I power off and power on after some time now i am not able to see rebooting

2. if i login in u-boot prompt and run "booot" command i am not able see rebooting

Hi Manu,

It appears Linux reboot by itself, right?

For testing, can you please add "init=/bin/sh" in U-Boot bootargs env to see if the auto reboot problem still happens?

BTY, please attach the boot log as a file, not directly copy and paste it to the thread. It makes the thread too long and difficult to navigate.

Liu,

i did via u-boot command "args_mmc "run finduuid;setenv bootargs console=${console} ${optargs} root=PARTUUID=${uuid} rw rootfstype=${mmcrootfstype} init=/bin/sh"

also please let me know in which file do we need to edit this.. i tried to edit in "u-boot/include/environment/ti/mmc.env" it did not showed in command line

when i searched i got below lists,

Liu,

i did via u-boot command "args_mmc "run finduuid;setenv bootargs console=${console} ${optargs} root=PARTUUID=${uuid} rw rootfstype=${mmcrootfstype} init=/bin/sh"

also please let me know in which file do we need to edit this.. i tried to edit in "u-boot/include/environment/ti/mmc.env" it did not showed in command line

when i searched i got below lists,

i am geeting kernel panic.. i think we have to do other changes.. with the above changes i am getting kernel panic,

Also here i am attached with configuration file of kernel please have a look

CONFIG_WATCHDOG=y
CONFIG_WATCHDOG_CORE=y

and rtc related,

CONFIG_RTC_DRV_PCF8563=y

as i am not able to upload complete defconfig i have mentioned as above

> [ 0.000000] Kernel command line: console=ttyO0,115200n8 root=PARTUUID= rw rootfstype=ext4 rootwait init=/bin/sh

The kernel boot log shows the rootfs is not defined correctly, this would cause kernel panic as shown in the boot log.

One way to add init=/bin/sh is to stop at U-Boot prompt, then run command:

=> edit args_mmc

then add " init=/bin/sh" to the end of the edit line, press "enter" key,

then run "boot" command to boot Linux.

Done, i have not observed reboot.. what is the observation with this ?

0 Bin Liu 1 month ago in reply to Manu kumar

TI__Guru*** 142066 points

"init=/bin/sh" directly runs the bash and bypasses systemd to initialize Linux, so this test result seems telling somewhere in systemd scripts is not happy and initiated reboot from Linux user space.

I don't have a clear direction in how to debug the problem, since I never saw such issue before...

The SDK provides multiple prebuilt root filesystems. Which one do you use on your board?

0 Manu kumar 1 month ago in reply to Bin Liu

Intellectual 410 points

We have used "tisdk-base-image-am335x-evm-20240620173038.rootfs.tar" root file system..

Also 1 more thing i observed that its not listing an modules ( i verified using command "lsmod" ) is there any other configurations or settings we have to do?

0 Bin Liu 1 month ago in reply to Manu kumar

TI__Guru*** 142066 points

Manu kumar said:

This is typically due to the mismatch between the kerne image and modules. When you modified kernel source and recompile the kernel, ensure you have also recompiled the modules too, and update both kernel image and modules to the root filesystem.

0 Manu kumar 1 month ago in reply to Bin Liu

Intellectual 410 points

Yes,

if run "bitbake linux-ti-staging " it automatically compile kernel driver modules rite? that we have done

0 Bin Liu 1 month ago in reply to Manu kumar

TI__Guru*** 142066 points

I am not a Yocto expert, but yes I believe the rootfs image generated in Yocto has the kernel image and modules populated properly,

0 Bin Liu 1 month ago in reply to Bin Liu

TI__Guru*** 142066 points

Okay, I think I just got lost in all the messages. I guess here is the situation:

you use tisdk-base-image generated in Yocto, but Linux automatically reboot towards the end of the boot process on your board. If "init=/bin/sh" parameter is added, Linux won't automatically reboot, but 'lsmod' command shows no modules are loaded. Is my understanding correct? Am I missing any information?
