Hi,
At first I was chasing why fw_setenv (see thread "fw_printenv works but
fw_setenv does not after switching to linux-fslc-imx 5.10.69 from
linux-fslc-imx 5.4.112") quit working after updating to linux-fslc-imx 5.10.69
from 5.4.114, but further testing has shown it might not be related to
fw_setenv itself as doing a flashcp to a MTD flexspi NOR device partition
doesn't work either.
If I simply try to copy a file with flashcp I get the following:
flashcp -v ./imx8mm-evk.dtb /dev/mtd7
Erasing blocks: 11/11 (100%)
Writing data: 40k/40k (100%)
Verifying data: 10k/40k (24%)File does not seem to match flash data. First
mismatch at 0x00000000-0x00002800
root@imx8mmevk:~# cat /proc/mtd
dev: size erasesize name

mtd6: 010f0000 00001000 "SquashFS"
mtd7: 00100000 00001000 "scratch"
I've checked kernel .config and device tree settings between the 5.4 and
5.10 series kernel and can find no issues that would explain why this is
happening.
Any ideas or tests to try are welcome!
Regards,
Brian
