Is this because U-Boot (active at DFU time) doesn't use hw ECC then?
Otherwise it would all come out in the wash?
Yup. Or, alternatively, we could try to make u-boot use the same
algorithm in software. Not sure what's easier to do.
Matt, you figured that one out when we had the same problem a while
ago on HXD8. Do you remember whether this was solved or if we just
worked around it by using the kernel (and not u-boot) to write the
rootfs ?
Well, we just write the rootfs via mtd utility at kernel layer.
And DFU did not do hw ECC handling at U-boot. You will see countless ECC
errors if you enable hw ECC logic for kernel and program the rootfs via
u-boot.
