SSP Demo Example is failing at buffer verify for LPC 1837

Hi,

I am using LPC 1837 controller and using Expresso IDE.I am trying to run the SSP demo example for SPI on two LPC boards.Following are my connections for that

Board 1:

=>Configured as Master.

=> P1.5 as SSEL which is connected to SSEL on other LPC 1837 board.

=> PF.4 as SCK1 which is connected to SCLK on other LPC 1837 board.

=> P1.4 as MOSI which is connected to MISO on other LPC 1837 board.

=> P1.3 as MISO which is connected to MOSI on other LPC 1837 board.

Board 2:

=>Configured as Slave.

=> P1.5 as SSEL

=> PF.4 as SCK1

=> P1.4 as MOSI

=> P1.3 as MISO

When I am running the demo application on both the boards and I am getting always buffer_verify() failure.Do I need to do anything beyond these connections or anything to be added in the code.

Regards

srikanth.
