imx6qsabresd board hangs at "Waiting for root device /dev/mmcblk1p2..."

I am trying to use u-boot, kernel and rootfs on the imx6qsabresd board without using yocto.

I put u-boot, kernel, and rootfs on the sd card and booted it.
-Waiting for root device /dev/mmcblk1p2...
-random: crng init done
No message appears after the message is printed.

In my opinion, u-boot and kernel are working, and rootfs seems to have a problem.

The sites I referenced are as follows.

Download list
-Cross compiler: gcc-arm-linux-gnueabihf (latest)
-u-boot: boundarydevices/u-boot-imx6/boundary-v2017.03
-kernel: boundarydevices/linux-imx6boundary-imx_4.14.x_2.0.0_ga
-rootfs: Installing with debootstrap(base ubuntu 18.04 LTS)

Hi jinsoo

 

for boundarydevices software one can look at below tutorial :

https://boundarydevices.com/customizing-ubuntudebian-kernels/

reason for "No message" may be that software was built for boundary boards,

not for imx6qsabresd board.

 

Best regards
igor
