Hi I use sdk0.4 0.5 before and everything is ok，but now I have to change sdk to v2.0，when I have ported uboot and kernel code，I found the nor flash can't be recognized in kernel showing the message below
[ 1.163198] of-flash 60000000.nor: do_map_probe() failed for type cfi_probe
[ 1.170224] of-flash 60000000.nor: do_map_probe() failed
and I found it fail at cfi_qry_mode_on in cfi_probe.c I'm so confused with this.Did someone meet this before?
Can you show some opinions？
