MCUxpresso SDK eMMC example

Hi everybody,

We have developed our own hardware with the LPC55S66 and eMMC memory. I couldn't find an example of how to configure and use the SDK SDMMC middleware with a eMMC memory. Is there an example somewhere or any of you have worked with eMMC memory and SDK before?
Your help will be of great help to me ...

Best regards

Serge

Many thanks Alice !

Now the first call to SDIF_SyncClockcommand() in MMC_CardInit() failed everytime and I don't understand why, any idea?

Best regards
