Is it possible to work with SD Card and WIFI/BLUETOOTH at the same time on mimxrt1170-evk?

Hi, it looks like SD Card and WIFI\BLUETOOTH working on the same sd-interface. Is that possible to run them both at the same time?

Hi @SCh ,

  Thank you for your interest in the NXP MIMXRT product, I would like to provide service for you.

  About the SD card and the WIFI/BLUETHOOTH module work at the same time, you just need to check, whether the MIMXRT1170-EVK these two modules share the same interface or not.

  Please check the schematic:

You can see, to the SDHC interface, the sdcard and the WIFI/Bluethooth share the same interface, so in the MIMXRT1170-EVK, you can't work at the same time for the same SDHC interface.

But, if the wifi/bluethooth don't use the SDHC interface for the communication, then you can use both of them.

Wish it helps you!

Best Regards,

Kerry
