    S25FL256L not responding after unkown time / error

    andre.schueer_2015491

      Reading the manufacturer Id etc. does not work.

      For all communication attempts the device does not respond.

       

      The same Software works on another Hardware.

       

      We have the Problem, that this behaviour keeps on Happening on our boards and we don't know why this is Happening.

       

      I tried to write to reset the device with the Software Reset command by writing a Software reset enable (0x66) first, followed by a Software reset (0x99).

       

      I also tried to send the mode bit reset command first (0xff).

       

      All These attempts seems to have no affect at all.


      We have to investigate the cause of this, because changing the flash-chip on the board solves the Problem but this should not be the case.

       

      Does anyone has any idea?

       

      Thanks in advance!
