[U-Boot-Users] cp.b not working

Hi,

I am working on Nios2 custom board with intel CFI j3 flash and my data bus is only 16 bit wide. The cfi driver I have modified with asm/io calls in order to by pass the cache. But now cp.w is working and not the cp.b and cp.l . What could be the possible reason as the saveenv (writebuf) is also working fine.

Thanks & Regards, Shinose.
