tcl_server: Support line buffers up to 4M (v3)

2015-09-30T21:01:00Z

Currently, the maximum size of a command sent to the TCL server is 4k. This patch increases this limit up to 4M. Reasoning: To get high-speed JTAG data transfers, I'm using a very long shift register. This reduces the overhead of the state changes, as well as the latency due to the common USB adapter transfers considerably. In order to submit those long DRSCAN commands to OpenOCD over the TCL/TCL interface, long TCL command lines are required. This is enabled by this patch. v3: Address review comments. Drop line instead of connection when realloc() fails. Changes in v2 of this patch: The line buffer is allocated dynamically to avoid an OpenOCD memory overhead if the large buffers are not used. The buffer starts at 4K and increases exponentially up to 1M, and then linearly in 1M increments up to 4M.

server: avoid the tcl server crashing when there is no target

Since commit 1d0cf0df37a4e831ca3121ba8987d5848cad3e42 ("server: tcl_notifications command") connecting to the tcl server would terminate openocd. Fix this.

Tcl exception codes cleanup, shutdown command amendments

2015-04-14T11:11:48Z

This patch might influence openocd Tcl commands behaviour in subtle ways, please give it a nice testing. The idea is that if an OpenOCD Tcl command returns an error, an exception is raised, and then the return code is propogated all the way up (or to the "catch" if present). This allows to detect "shutdown" which is not actually an error but has to raise an exception to stop execution of the commands that follow it in the script. openocd_thread special-cases shutdown because it should then terminate OpenOCD with a success error code, unless shutdown was called with an optional "error" argument which means terminate with a non-zero exit code.

server, target, cortex_m: add deinit_target to the API to free resources

2015-03-09T08:34:46Z

This should facilitate dynamic target creation and removal. Currently it helps with getting 0 bytes lost report from Valgrind on exit (after talking to a nucleo board). However, 1,223,886 bytes in 5,268 blocks are still reachable which means the app holds pointers to that data on exit. The majority comes from the jtag command queue, there're also many blocks from TCL command registration.

gdb_server: ignore stray + in ACK mode

2015-02-22T16:16:06Z

I couldn't make OpenOCD to work with GDB. I was always getting this in GDB: (gdb) target remote localhost:3333 Remote debugging using localhost:3333 Ignoring packet error, continuing... Ignoring packet error, continuing... Ignoring packet error, continuing... Ignoring packet error, continuing... Malformed response to offset query, timeout (gdb) While debugging gdb remote protocol, I have seen that gdb responds with: w ++$?#3f And those two '+' seems to confuse the OpenOCD parser, if it sees another '+' sign it emits the DEBUG output and sets the noack_mode to 2. The problem is that we weren't even IN noack mode, this was set to 0 and then it explicitly sets it to 2 and thus turning the noack mode on.
