[bitterblossom5486]

I generated an image: imx-robot-core-imx8mmevk-20211201053319.rootfs.tar.bz2 according to this tutorial: https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX-%E6%9C%BA%E5%99%A8%E4%BA%BA%E5%B9%B..., then I tried to burn it into the board via the command below:

I met a bunch of errors when I boot it up:
