Forum Post: AM335x PinMuxUtility - MMC2 - DUAL MUX

Hi,

I'm using a PinMux configuration for a custom board with the AM3352. In our design we adapted the configuration of MMC2 for use the pins DAT0, DAT1, DAT2 and DAT3 in MUX1 and the pins SDIO_CMD and SDIO_CLK in MUX0. Since the PinMuxUtility did not indicate warnings or errors, we considered this dual mux a valid configuration, but in our development we are facing some troubles to bring up this interface ON. I did not find any clear information about these parameters.

Can I merge MUX1 and MUX0 for MMC2 like I did?

I attached the configuration file for better analysis. (Please visit the site to view this file)

Thanks!!!
