Hi Andy! Did you check chapter 3.1.2 in the in the PruReferenceGuide? The PRUSS cannot access memory in the range of 0x0000_0000 to 0x0007_FFFF unless this feature is enabled through the PMAO register of the PRU-ICSS CFG register space.
I recommend to use the external memory for your buffer (up to 8MB), which gets allocated by the pruss_io driver. See this link <http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/_cha_memory.html> (last section ERam) for details. BR @William It sounds like you're creeping into memory reserved by "something else". Reserved memory from the PRUSS point of view -- haha! -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
