i.MX8MP initramfs failed to take effect in kernel

[jimmyli]

Hi，

      Below is my steps to build initramfs on i.mx8mp platform, but failed.

      Can you help to check and fix it ?

      Thanks very much.

1>Steps:

a. Create initramfs file directory，using busybox init to boot;

b. Make initramfs file system;

     find ./initramfs | cpio -H newc -o | gzip -9 -n > ./initramfs.cpio.gz

c. Copy initramfs.cpio.gz to kernel project in usr file

d. Open kernel initramfs configuration;

e. Build the kernel

    make Image -j30

2>File Tree:

root@Ubuntu-X64:/mnt/rfs# ./tree initramfs

Hi @jimmyli 

According to the Kernel panic, suggest to check the followings:

if build the fs for the partition on a Linux OS or not.

if the partition (mmcblk2p7) is correctly set as root or not.

Best regards

Harvey
