QCA9531's GPIO bitbang problem for cs_change #12

Closed sheenhx closed 8 years ago

sheenhx commented 8 years ago

I successfully connect the IMST's lora gateway board to MT7628 with native SPI.

However, when it comes to the QCA9531 which doesn't port native SPI pins, it didn't work.

I tried SPI-GPIO bitbang, and it works for the other devices. But when I use the lora gateway,the CS pin behaves really wired.

So I disabled cs_change then. It works!!

Is there anyone who can tell me why did this happen?

Environment: OpenWrt CC15.05 Kernel 3.18.27
