SPI Read Not Working

Question asked by Jie Liu on Sep 29, 2016

I use the sabreauto board to communicate to the other board with SPI interface.

But, I cannot get the data from SPI Interface. 

I use the oscilloscope to check the CLK signal, and the write operation can generate the CLK signal,

but the read one cannot.

Linux version is Linux version 4.1.15-1.1.1

CPU: ARMv7 Processor [412fc09a] revision 10 (ARMv7)

Please, give some hint about this issue. Thank you.

The test source and log is attached.
