imx93evk zephyr flashing jlink

[zefox]

Hi everyone, 

I am trying to get my brand spankin' new imx93evk board to work with a basic zephyr example. I am trying to get it to flash by following these two lines from the i.MX93 EVK board webpage (https://docs.zephyrproject.org/latest/boards/nxp/imx93_evk/doc/index.html

# From the root of the zephyr repository
west build -b imx93_evk/mimx9352/a55 samples/synchronization
west flash

((.venv) ) fox@ubuntu2204:~/zephyrproject/zephyr$ west flash
-- west flash: rebuilding
ninja: no work to do.
-- west flash: using runner jlink
-- runners.jlink: JLink version: 8.46
-- runners.jlink: Flashing file: /home/timon/zephyrproject/zephyr/build/zephyr/zephyr.bin
FATAL ERROR: command exited with status 1: /opt/SEGGER/JLink_V846/JLinkExe -nogui 1 -if swd -speed auto -device MIMX9352_A55_0 -CommanderScript /tmp/tmp3mpcn6xdjlink/runner.jlink -nogui 1

i am not really sure what i am doing wrong, i have tried the regular emmc boot mode where i stop it in u-boot, then run:

dcache off

 then flash. Also i have tried putting it in the Serial Downloader mode. But i keep getting the same error. 

any help would be greatly appreciated

with kind regards, fox

Hi @zefox 

    Have you resolved the issue ? I also have such a question when execute command "west flash " to IMX93_EVK board under boot .

Hi,

Nope, the documentation in the zephyrproject is incorrect. Looking at documentation on the Nordic Semiconductor website it gives the correct ways on how to implement this. But i’ve since abandoned trying to get this to work.

trying to continue to debug this, i found out when i run it from the emmc. Then try to even connect with my jlink, I get this output:

so the watchdog might be interfering. I am just not sure how to get this to work?

Hello @zefox 

I hope you are doing ver well.

Unfortunately, this support channel does not provide support for Zephyr.

Also, If you have your binary or elf file compiled, you can try to load with remoteproc or in U-boot. 

Best regards,

Salas.

Hi @Manuel_Salas 

thanks for the response! 

that’s unfortunate… is it possible then to debug the application when i have started it from u-boot or remoteproc?

[Manuel_Salas]

Hello @zefox 

It should be possible in U-boot.

Please take a look to the chapter 4 Prepare the board for the debugger of AN14120 Debugging Cortex-M with VS Code on i.MX 8M, i.MX 8ULP, and i.MX 9, there is explained how you can debbug it with VSCode.

Best regards,

Salas.
