**** BEGIN LOGGING AT Sun Jun 16 02:59:58 2019 Jun 16 16:40:24 dps through pipes, sounds mad? e.g. a c program sends float numbers to stdout to another to integrate. is any package already there? Jun 16 16:41:29 or maybe unix domain sockets Jun 16 16:42:15 or a lib instead of a package... Jun 16 20:54:12 CoffeeBreakfast: if that is supposed to be a question rather than rambling, you should probably try phrasing it a lot more clearly Jun 16 20:54:17 :P Jun 16 23:02:37 zmatt: I can access the debug registers using the memory mapped registers Jun 16 23:17:12 yay! :) can you do anything with it though? Jun 16 23:38:53 I am still getting to that point, I can access and clear the breakpoint registers which is encouraging. I am still working on the sequence to unlock the registers after power up. I am stuck dealing with an MMU issue as the text sections need to be made READ/WRITE, they default to READ-ONLY. The common RTEMS call is using a HYP mode c15 instruction which causes an exception on the BBB but is ok on the A9 Zynq. Jun 16 23:39:15 why would the text sections need to be read/write ? Jun 16 23:39:37 cortex-a8 doesn't have HYP mode Jun 16 23:39:37 software break points Jun 16 23:40:04 Yeah, the code was added for the latest RPi's which boot in HYP mode Jun 16 23:41:00 yeah but I mean, software breakpoints aren't strictly needed when you have hardware breakpoints Jun 16 23:42:04 That is true, we have a remote GDB server interface and so I leave that to gdb to figure out. Jun 16 23:44:34 have you been successful in asserting DBGEN? (you can confirm via the DBGAUTHSTATUS register) Jun 16 23:46:45 I have not touched the hardware Jun 16 23:47:00 I have not dumped that register Jun 16 23:48:34 without that step, your efforts will be fruitless since no debug exception will ever be taken (except for the BKPT instruction) Jun 16 23:51:09 Sure, I am working towards that point Jun 16 23:51:17 ok **** ENDING LOGGING AT Mon Jun 17 02:59:57 2019
