I'm trying to interface Murata WiFi / BT module LBEE5ZSTNC-523, with a customized and connected in MMC3 board.
But this not working. I followed all the tutorial:
a)processors.wiki.ti.com/.../WL18xx_Platform_Integration_Guide
b) processors.wiki.ti.com/.../SD_Driver's_Guide
My settings are:

Could someone give me a hint? The problem in this MMC3 or some other configuration?
Thanks
