And on the ARM: void* p; prussdrv_map_prumem(PRUSS0_SHARED_DATARAM, &p); shared_ram = (volatile unsigned int*)p; unsigned int foobar = shared_ram[100]; Thanks for the quick reply :) -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
