Is your board really similar, i. e. did you copy all the CPLD stuff from MPC5121ADS as well? Otherwise, ARIA might be a better choice to copy code from. > In order to boot-through to the console I needed to disable a bne on a > compare failure under relocate_code: in cpu/mpc512x/start.S.

So the content of the RAM where the code got copied to is not identical to the content of the flash where the code got copied from ==> RAM error.
