SPI Slave not get interrupt



I have a board with SPARTAN 6. my FPGA used as a slave and I use AARDVARK as master. I based my code on the xilinx spi_slave_interrupt example. but I see some strange behavior..


when I use the function xspi_transfer as receiver only (one buffer) - I get the data as I expected.

but when I use 2 buffers - one to receive and one to send - I don't receive anything and not sending.

I'v all ready try to change the modes (clk phase, clk polarity) but with no success


another strange thing is when I connect scope to the SPI wires the receiveing and the sending are working!


please help me :)
