J784S4XEVM: Reboot Command Blocks for ~2 Minutes

Gokhan Ugurel
Prodigy 85 points
Part Number: J784S4XEVM

Tool/software:

Information: 

Platform: J784S4XG01EVM

SDK: ti-processor-sdk-linux-adas-j784s4-evm-11_00_00_08

Boot Mode: SD Card

Image: Prebuilt image generated with "create-sdcard.sh" script. No customization performed inside image. 

Problem:

Hi,

When i use reboot command inside terminal, shutdown services of Linux takes approximately ~2 minutes and then system reboots without problem.

Is it normal behavior?

If i comment the line "name_overlays=ti/k3-j784s4-evm-ethfw.dtbo ti/k3-j784s4-vision-apps.dtbo" inside uEnv.txt, i do NOT experience this behavior. 

Also, i do NOT experience this behavior with ti-processor-sdk-linux-adas-j784s4-evm-10_01_00_05 whether i comment above line or not.

I attached the kernel logs below when i initiate "reboot" command and blocked by ~2 minutes.

    Hi Gokhan,

    Thanks for the details. Seems like a task is blocking shutdown. I recollect seeing this behavior.

    # Blocks here for 2 minutes
    [ *** ] (1 of 2) A stop job is running for …c1 of User weston
    [ *** ] (2 of 2) A stop job is running for …ty display manager
    # Then continues

    Is it okay for you to comment out vision_apps or you need that?

    Hi Keerthy,

    I need vision_apps device tree overlay file (k3-j784s4-vision-apps.dtbo) to be able to use the remote logging system. But since we are physically close to the evm boards, we can use the power switch on the board for now. In future, if we need to reboot the board through ssh, etc this could be a problem. Just wanted to report to you in case you are not aware.

    Thanks
    Gokhan

    Thanks Gokhan .. I will raise an internal bug and push for the fix for next release.
