Atmel ARM SAMA5: Driving PCK (Programmable Clock) Output as clock to FPGA
Dear forum members,
I have an ATMEL ARM SAMA5D31 board, that I would like to interface to an FPGA. One of the things I would like, is to have the ARM generate a clock (approx 100MHz) for the FPGA.
I think the PCK outputs can be used for that purpose, but so far I have not been able to use these pins as clock outputs.
I am using a at91-buildroot based linux 3.6.9 with glib and device-tree support.
Does anyone know how to set up this output to produce such a clock?
The frequency is not critical.
Thanks in advance,
