LinkIt ONE + CAN-BUS Shield issue

I tried to connect the two devices, the CAN-BUS Shield didn’t respond.
I used the Seeed’s example code, the Serial Monitor responds “CAN BUS Shield init fail”

Look from the oscilloscope, the MOSI is correct, but MISO still “HIGH” always,

Please help me, thanks.
My CAN-BUS Shield is v1.2 11/03/2014

I had your same problem, and I solved it by adding pinMode(SPI_CS_PIN, OUTPUT); in the setup
