Hello,

I am trying to program an extern flash memory with QSPI of my coldfire 52235EVB but I don't succeed.
When I read the status register I don't get what I am supposed to have. for example when I send the command Write Enable I am supposed to have the corresponding bit set to 1 but I haven't.
When I program some bytes of the memory and after I read it I don't get what I write.
I am using a flash memory of spansion (S25FL) but maybe I will change if somebody know a good flash memory.
Does somebody had already have this kind of problems ?
Does anybody have some example of code to program an extern flash memory with QSPI ?

thanks.

Fabien
