This patch fixes crc32 error on Big-Endianness system by conversion of
|
|
calculated crc32 value.
|
|
|
|
Little-Endianness system:
|
|
|
|
obtained crc32: Little
|
|
calculated crc32: Little
|
|
|
|
Big-Endianness system:
|
|
|
|
obtained crc32: Little
|
|
calculated crc32: Big
|
|
|
|
log (APRESIA ApresiaLightGS120GT-SS, RTL8382M, Big-Endianness):
|
|
|
|
[ 8.570000] u_boot_env 18001200.spi:flash@0:partitions:partition@c0000: Invalid calculated CRC32: 0x88cd6f09 (expected: 0x096fcd88)
