This is the output on the kontron bl-imx8m board:

Just tried with the same v2.4 TF-A version:

Hit any key to stop autoboot: 0 => [55;203R Unknown command '[55' - try 'help' Unknown command '203R' - try 'help'
and the serial garbage is seen.
My version has 4GiB of RAM, yours has only 1GiB.
Could this make a difference?
I can hardly imagine it. I don't have an explanation for it.
Thanks
