I have tried to adapt an example where the host program writes a value to the ddr memory and the pru reads these values and outputs the values to a gpio pin. but somehow i did not manage to read the correct data from the memory. i am new to this topic (especially memory management), so this might be a simple question, but i somehow don't get this right.
using prussdrv_get_phys_addr in the host program gives me a physical address of 0x9f700000 (it somehow always gives me this value ?), which i send to the pru with an array created by prussdrv_map_prumem. is this the correct adress to read data from in the pru or do i have to use a different one? I think i have missunderstood something, so if anyone knows the solution or a good source for learning to use these kind of things, i would appreciate any help. also if someone knows a way to display a register's value (without ccs), please let me know. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
