I am simulating a simple code using atmel's spi libraries for At91sam7x256 in keil debugger. For days i have been trying to get the simulation running but i can see no signal change on Spi clock and signal pins in the virtual osciloscope. I can see however that the chip select signal is changing levels but there is no change of signals on MOSI and SPCK pins. Supposing everything else is correct about the code (i mean initialization) is this normal?
