Dear Simon,
In message 97f8b0ec-103b-e9b7-42ed-e1922f6d489a@gmail.com you wrote:
Oops, I'll have to take that back. I just checked and SPL *does* boot the uImage U-Boot also if I deliberately corrupt the CRC of the image. So you're right, it seems to be not protected at all!
Is that expected behaviour or a bug?
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.
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?
Regards, Simon
