Hi, I would like to get communication up and running between ARM and PRU, by following the TI Example 5 "RPMsg communication between ARM and PRU".
The system is a BBB with debian, kernel 4.1.15-ti-rt-r43. All 3 modules are loaded, here is the snippet of the lsmod: pruss_remoteproc 15296 2 rpmsg_pru 4683 0 virtio_rpmsg_bus 13437 1 rpmsg_pru dmesg ourput is posted below, I however don't see any problems or errors. However the device file /dev/rpmsg_pru* is not created at all, although the rpmsg_host seems to be online. What am I missing? Where to look for error messages or problems? Could it be a problem with the device tree? I don't have any device tree overlays loaded, apart from the cape_universaln Best Regards, JD [ 137.089974] pruss-rproc 4a300000.pruss: 8 PRU interrupts parsed [ 137.090107] pruss-rproc 4a300000.pruss: memory dram0: pa 0x4a300000 size 0x2000 va e0b68000 [ 137.090153] pruss-rproc 4a300000.pruss: memory dram1: pa 0x4a302000 size 0x2000 va e0b6c000 [ 137.090193] pruss-rproc 4a300000.pruss: memory shrdram2: pa 0x4a310000 size 0x3000 va e0b70000 [ 137.090231] pruss-rproc 4a300000.pruss: memory intc: pa 0x4a320000 size 0x2000 va e0b74000 [ 137.090270] pruss-rproc 4a300000.pruss: memory cfg: pa 0x4a326000 size 0x2000 va e0b78000 [ 137.106091] pruss-rproc 4a300000.pruss: creating platform devices for PRU cores [ 137.117092] pru-rproc 4a334000.pru0: memory iram: pa 0x4a334000 size 0x2000 va e0b7c000 [ 137.117188] pru-rproc 4a334000.pru0: memory control: pa 0x4a322000 size 0x400 va e0b80000 [ 137.117231] pru-rproc 4a334000.pru0: memory debug: pa 0x4a322400 size 0x100 va e0b82400 [ 137.128119] remoteproc1: 4a334000.pru0 is available [ 137.128152] remoteproc1: Note: remoteproc is still under development and considered experimental.
