Thanks ! Sadly I am still not able to bring up the WiFi module (Silex part (SDMAC),QCA9377 using SDIO).
I can't find the right firmware for it (I tried the firmware from https://github.com/kvalo/ath10k-firmware/tree/master/QCA9377/hw1.0/untested , but keep getting "Invalid Firmware magic"). I am working with the vendor (Silex) to get a valid firmware blob for the part.
