Kernel panic when using cpio.gz.u-boot

[raymondman]

Our custom board is using iMX8MM with 1GB LPDDR4. Yocto is HardKnott version. We want to use example_kernel_emmc.uuu to program the custom board. The RAM size and the lpddr4 timing have been updated in both U-boot and kernel. However, the cpio.gz.u-boot produced by "bitbake fsl-image-mfgtool-initramfs" does not work. Below is the log. (We also use NXP pre-built file to test, but get the same kernel panic.) Please advise.

Hi!

I have a custom board with 1G LPDDR4. I made some custom on dts. The release used was 5.15.32-2.0.0. The system works except of:

[ 0.000000] OF: reserved mem: failed to allocate memory for node 'linux,cma'

If you fix your problem I really appreciate any tips.

Thanks in advance.
