Hi All, I am currently trying to perform DMA transfers between 5509A and an SD Card connected via McBSP1, which is configured in MMC/SD Mode. I set-up my DMA source as a buffer in DARAM (auto post inc) and my destination as MMCDXR, and use MMC/SD1 Transmit Event (XMMCEVT1) as the Sync event via the DMA Channels CCR register. For whatever reason, my DMA transfer does not trigger auto...

Dear list, I have difficulties to boot up from SPI flash: IO4 goes down, DSP read data, but IO4 doesn't rise again. So DSP doesn't start to execute. TI support told me EMIF.ARDY has to be pulled up to make boot loader successful. I think it's irrelevent since EMIF.ARDY is only for EMIF. I doublechecked the datasheet and see nothing relate EMIF.ARDY to SPI bootup. I know many people in this list...
