nrf51822 SPI Slave not working

[Maidu]

I have two custom boards with nrf51822 QFAAG0 1348AC chip. I use 16 MHz crystal. Bluetooth functionality is working fine but SPI does not work. SPI pins are P0.00 ( MISO ), P0.01 ( MOSI ), P0.02 ( SCK ), P0.03 ( SS1 ). I use spi master and slave example code ( spi_master_example, spi_slave_example ) from sdk folder "nrf51822/Board/nrf6310/". All pins are configure according to my SPI pins in code (SPI, LEDS). From master side I see that everything is changing in registers but from client side I dont get any action.

Is there something more what I need to configure or change?

If you're using the softdevice and SDK and the nRF6310 version of the code examples it will by default use those pins for input buttons. You should re-route either buttons or your SPI interface to Port 2 or 3 to avoid using same pins for same functionality.
