    Custom GPIF design: only first 28 bits are toggling!

    user_250433950

       Hi,

         

      I want to know if anybody sucessfully used the GPIF port in 32 bits mode with DMA and with a custom GPIF project (not with a pre-prog GPIF interface like the SLAVE FIFO interface of Cypress)....

         

      If I'm using a provided code for my DEVKIT (not the one from Cypress, but from a third party), the GPIF is working fine in 32 bits mode with the SLAVE interface... So my hardware is fine. But with the AN75799 code modified to work with 32bits GPIF, only the first 28bits are toggling....!

         

      Anybody has any success with this port in 32bits mode in custom GPIF designer project?

         

      Regards,

      P.S.: I already opened a case!
