i.mx233 SPI and SDcard

     I'd like to know if I can use an SD card and an SPI device in the same design with an i.mx23. The SD card and SPI share some pins and the datasheet doesn't mention whether or not they will operate at the same time. I want to boot from an SDcard and access an SPI peripheral during run time. I also want to store data to the SD card while running (logs). Does anyone have any experience with this?

Thanks

Yes you can, but on different SPI blocks (there are two identical SPI blocks in MX233). Another options is that while you can not switch between SD/SPI mode at runtime on a single SPI block, you can operate the SD card in SPI mode.

Great! Thanks for your response. That should work for me.
