1.392352] Warning: unable to open an initial console.   ==> You last thread shows ttymxc3 is ok for your inmate, but here it gone?
[ 1.397384] Waiting for root device /dev/mmcblk2p2...   ==> please make sure the interrupt of sdhc controller you assigned to inmate is correct. Check the inmate cfg file. Also disable the sdhc in root cell device tree. 
[ 11.606455] mmc2: Timeout waiting for hardware interrupt.

So make sure mmc2 clock is set up by root cell(inmate does not has capability to touch clock controller, so need root cell to config it), and mmc2 interrupt and memory is correctly set up in inmate cell and inmate device tree.

Hello @jimmyhua 

Are you using the EVK or custom board?

Could you please share more steps to try to reproduce it by my side?

Best regards,
