kernel panic when booting the s32v234sbc

[nskang]

Sorry, i'm not good at using English.

I have a s32v234sbc package and i am trying to boot it with yocto image.

(* VisionSDK_S32V2_RTM_1_5_0_img_yocto.tar.gz)

Used image is yocto origianl image(Image, fsl-s32v234sbc.dtb, u-boot.s32)

however, always kernel panic occurs as below.

please, let me know how to figure out it.

* i already check that kernel panic occurs when loading the seq.ko module.

Root cause might be related to missing cse.bin. If the device is security enabled (which is true for latest SBCs) seq.ko will fail loading.

Best regards,

Dear Stefan Schwarz

many thanks for your answer.

I'm in a trouble still playing demo with SBC-S32V234 board. 

i can't anything with it.

i hope that you assist me to solve my issue.

Issue 1.

As you know My SBC-S32V234 board can't boot with Yocto binary Image which is downloaded from NXP web.

<You already answered about this issue>

but i can't make cse.bin file because i only have a u-boot.s32(Yocto) Image not Yocto source code. 

so, if you know that how to change device security option from enable to disable. please let me know. i will try.

Issue 2.

Always SBC-S32V234 board hangs with "Buffer overrun" message when executing a sample application(elf)

Thanks.

i got it your said's mean.

but, i'm not sure that what shall i do.

i already said that i used yocto binary image from web.

how can i solve this problem.?

[Daniel_Popa]

Hi stefans‌

FYI. 

Do you know what might be wrong here?

Thank you!

Daniel

[dakshina_dasari]

I am also facing the same problem.

The solution is not clear.

Can you please elaborate -- how can i build the cse.bin? and where do i place it?

Also can i disable it for building the seq.ko?

Regards,

Dakshina
