Hi Chris, You will want to use
char * pointer; prussdrv_map_prumem(PRUSS0_PRU0_DATARAM, (void **) &pointer); This will give you a memory pointer to the PRU 0 data memory. You can use the pointer to read or write memory. Be sure to declare the memory are volatile in the PRU C code, or the compiler will optimize reads and not read the new values. You can get more details on the TI web site: http://processors.wiki.ti.com/index.php/PRU_Linux_Application_Loader_API_Guide -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
