The 2020.10 tagged build works on the T2080RDB card, however, all tags starting with 2021.01-rc1 no long boot from SD-card on the development system. This might also apply to other QorIQ development boards.

Here is a dump of the crash which occurs very early in the process (the left column is a timestamp):
