Problem booting Angstrom 2016.12 on imx28evk

sonuabraham — Mon, 22 May 2017 06:38:53 GMT

Hi ,

I am trying to build Angstrom 2016.12 based systemd-image for imx28evk.

I have placed u-boot.sb in the fist partition of the SD card and I am using tftp boot for the kernel image and NFS for the root file system.

I am getting the following error at the last stage of the boot process.

I have attached full kernel logs and my u-boot environment settings below ..

Please guide me how to debug the Kenel panic or suggest me if I am missing out some settings in kernel configuration ..

Thanks in advance ...

Hi Sonu

most possible reason is ddr errors, one can find optimized setting with tool on

https://community.freescale.com/docs/DOC-1455

https://community.freescale.com/message/375692#375692

other reason may be brownout exceptions, one can add debug printfs or run application

with jtag step by step to find out it.

Best regards
igor

Hi Igor,

Thanks for the information .

I added few more logs by changing the kernel boot parameters and got the following log

Looks some components related to virtualization is missing ..

Is there any configuration settings for enabling the virtualization components when building the kernel for imx28evk boards.

Thanks,
