Dear Simon,

I don't know your board.
It may be intentional, for example if there are size restrictions for the SPL wich don't allow to include the CRC32 code...
I don't think this is intentional. I discussed this in another thread with Marek by now. There is no reference to the CRC code in the files in common/spl or the funtions called by it.
Depending on hardware capabilities, this may be indeed intentional, for example to keep the size of the SPL below a certain limit or to allow for other, more critical features instead.
Searching the whole code, I cannot see anything that checks the uImage CRC from standard SPL. And I don't see board specific controls to do this check, did I miss something?
This may well be possible. But then, this is usually stage two already - the ROM bootloader did not check any SPL checksum either...
Best regards,
Wolfgang Denk
