Hi all,
I have a board with at91sam9260 configured as little endian (via strap pin). The u-boot is working quite well. On the board there is a chip whose driver was written for PowerPC that is big endian. Unfortunately the
driver was
written in a bad way and it is difficult to fix endiannes dependencies.
I
thought to change the endianness of the processor to big endian. I recompiled everything with a big endian compiler but the u-boot is crashing. Should
I
change something on my hardware?
The AT91 series is strictly small endian.
Before there is an argument, I'd like to point out people came to the conclusion that "the only good endian is a dead endian" years ago.
But my processor has a pin I can configure to change the endianness. Why are you saying it cannot support big endian?
