Try 'dap apcsw 1'.
Thanks. Quick test seems to show it still produces the same error. If I do "dap apcsw" I get back: apsel 0 selected, csw 0x40000000 And I get the same result after running "dap apcsw 1". Not sure if that is right. I should add too that when the target is in the run state I get a lot of this coming out: JTAG-DP STICKY ERROR MEM_AP_CSW 0x80000042, MEM_AP_TAR 0xc2301080 Polling target armada370.cpu failed, GDB will be halted. Polling again in 100ms JTAG-DP STICKY ERROR MEM_AP_CSW 0x80000042, MEM_AP_TAR 0xc2301080 Polling target armada370.cpu failed, GDB will be halted. Polling again in 300ms After a while it will come back with: Polling target armada370.cpu succeeded again When I halt it that output stops.
