Kernal panic error while boot from SD card

Hi,

I have flashed the .sdcard image into a SD card. And trying to boot it.

The booting gets stopped with following error.

Hi Omsakthi

what processor and bsp used in the case. Please look at nxp linux documentation on

i.MX Software|NXP

Check what "mmcblknp" should be used, it is described in Release Notes

Table "Common kernel boot parameters".

Please use nxp bsp:

linux-imx - i.MX Linux kernel

Best regards
igor
