SPI: Data OUT falls low when Read command is sent


Does anybody knows how to keep OUT line in HIGH while Read command is sent to SPI? My SPI on SL6087 is already partially working, but Data OUT line is falling to LOW after Read command is used. It looks that connected SD card is blocked in this case. Thanks a lot for any help. Reagrds. Mirek



Can you give more details on the SPI configuration, chip select and sample code, if possible.


Hi paruthiv, we already solved it. It looks described state was not the main problem. We send couple of FF after every Read a Write commands and communication is quite stable now. Mirek
