SPI protocol in my PSOC4 BLE kit won't work if pins given below are selected:
P4.0=SCB1_SPI_MOSI[0]
P4.1=SCB1_SPI_MISO[0]
P5.0=SCB1_SPI_SS0[0]
P5.1=SCB1_SPI_SCLK[0]
If I select pins as given below SPI protocol works
P0.0=SCB1_SPI_MOSI[1]
P0.1=SCB1_SPI_MISO[1]
P0.2=SCB1_SPI_SS0[1]
P0.3=SCB1_SPI_SCLK[1]
please help I have attached program below.

Hi,
P4.0 and P4.1 have capacitors connected that are normally used for CapSense, did you remove them?
kind regards,

P5.0 and P5.1 are connected to the F-RAM's SDA and SCL. So, it is assumed that the F-RAM device drives SDA or SCL. If you want to use these pins on the CY8CKIT-042-BLE PIONEER Kit, the F-RAM device and the pull-up resistance must be disable at these pins.
Remove the F-RAM device U3 and the resistance R31 and R35 from the BLE Pioneer board. I don't find any other smart solution right now.
