Write problem. on Micron MT25QL256

[msthrax]

I have a weird problem using this library to write data on flash. Actually no write operation take place on Flash. I wrote a new library for that(attached). Also I got same problem. I found out that the problem comes from 4-Byte Write Operation. When I use 3-Byte command, there is no problem.

Hi. is compatible flash? did you check registers?

[msthrax]

Actually I did not, but I compared commands. The point that took my attention, was my own lib resulted the same as you.
