Re: 25fl256 not erase
The status of "a" means there is some sort of protection. Read the datasheet
"S25FL128S and S25FL256S" datasheet. (Very long one 154 pages)
Try the following command
"w 6"
"w 1 2"
The try to erase,if not we need to dig deep into the datasheet.

Re: 25fl256 not erase
Read the datasheet to see what command needed to unlock the protection.
