The only platform-dependence is the endianness, and if you had that
wrong it wouldn't manifest itself as CRC errors.

Can you read back the contents of the flash from /dev/mtd4 immediately
after writing them, but before you attempt to mount JFFS2? Check that
there is no corruption there.

I'm a little suspicious of the CRC which your system says it
_calculated_. It wants 0x00000000, then 0x715da5a5, then 0x56361fba,
which don't seem entirely likely to me.
