u-boot error: No partition table - mmc 2 Couldn't find partition mmc 2:1

[vprajapati]

I am working on imx8mp custom board which has 2 GB DDR4 RAM. It has 64 GB of emmc. I am flashing yocto images which has Kernel 6.6.23 and U-Boot 2024.04

First time I made some customization and flashed that image, it is working well. Then 2nd time, made some customization and added some debug logs in kernel and u-boot. The image stopped working and each time stucks in u-boot console. Even the first image that was working previously, it is not working now. 

The u-boot logs with environment is showing below.

I try to erase emmc and re flashed the image, still the same problem.  What should be the issue here any detailed debugging steps would help me.

I am flashing wic.zst image created by yocto using uuu utility using below command
uuu -b emmc_all imx-boot-ixm-ecoface-sd.bin-flash_ddr4_evk ixm-ecoface-image-ixm-ecoface.rootfs.wic.zst

I am attaching my board def config file, dtsi files and .c and .h files for board.

Thanks.
