I have successfully loaded and run a simple hello world program on the BF537 Stamp target using blackfin-toolchain-uclibc-default-2014R1-RC2 tool chain. The stamp target already had an uClinux image preloaded.
I now want to implement a simple program to control the peripheral hardware - in the first instance I would be more than happy to turn a led on and off in response to a push button action.
I am at total loss as to where to start - the online documentation is helpful but contradictory and takes you down many blind alleys. If some one could just start me off with direction to the relevant pages that describe coherently how this can be done I would be extremely grateful.
