Tool/software:
Now I have divided the emmc into two partitions. mmcblk0p1 has been allocated 10M for storing private data, and the remaining space has been assigned to mmcblk0p2. Then I extracted the tisdk-edgeai-image-j722s-evm.rootfs-20250918010209.tar.xz file to mmcblk0p2. Now I am unable to boot from the emmc. Where should I make the correction?
