Dear Simon,
In message CAAh8qsyopV-HftdCWMbMu+fdcpqWWQtBnZDDyqFyv6iC1eoCDA@mail.gmail.com you wrote:
Only if you use signed images. With plain U-Boot, there is not even a checksum for it...
When SPL loads U-Boot from a legacy image, isn't there a CRC involved over the full image including the environment?
Yes, but when - for example - the compiled in default environment gets corrupted while loading from the storage device or while writing it to RAM, there will be zero check when reading it.
Best regards,
Wolfgang Denk

Randal said it would be tough to do in sed. He didn't say he didn't
understand sed. Randal understands sed quite well. Which is why he
uses Perl. :-) - Larry Wall in 7874@jpl-devvax.JPL.NASA.GOV
