Hi Jeff,
I seem to be having a problem with fw_printenv on my PowerPC 85xx target whereby I constantly get CRC32 errors:
# fw_printenv Warning: Bad CRC, using default environment
I tracked this down to the fact that u-boot/lib_generic/crc32.c is getting compiled with the __LITTLE_ENDIAN defined even though I have CROSS_COMPILE setup correctly [e.g. I can build u-boot.bin just fine].
This makes little sense to me, as then the crc version used in U-Boot would also use a wrong endianness. Are you sure this happens? Las time I used the tool it worked for me without any such hacks.
hmm, I recently discovered that normal user space headers always define both __LITTLE_ENDIAN and __BIG_ENDIAN so therefore a # ifdef __LITTLE_ENDIAN # define DO_CRC(x) crc = tab[(crc ^ (x)) & 255] ^ (crc >> 8) # else # define DO_CRC(x) crc = tab[((crc >> 24) ^ (x)) & 255] ^ (crc << 8) # endif
Wont work. One have to use #if __BYTE_ORDER == __LITTLE_ENDIAN instead.
Problem is that I don't think u-boot #defines __BYTE_ORDER so that would have to be added too for all archs: #define __BYTE_ORDER __LITTLE_ENDIAN or #define __BYTE_ORDER __BIG_ENDIAN
