Codeblocks MCU / OpenOCD plugin

<< < (3/7) > >>

Hi, its me again ;-)

I got further, and could build all the project in your workspace.
I did compile cb earlier with the project files therein.
I didn't know I have to build them in your workspace in the right order.
Anyway, after building and running update.bat I got my own version own CodeBlocks :-)

Starting my STR7 project a screen shows up telling me to select a MCU.
Under Project/Properties there is a MCU tab.
But there is nothing to select there.
Probably I have to copy some plugin files to somewhere ?

I copied the mcudrv directory to
\output\share\ CodeBlocks\plugins
Now I'm able to select MCU and settings.
A quick test lets me break the program.
After that the controller resets, maybe because
the active Watchdog of my STR7.

I'm missing the Envars and Library tabs in the project settings!

I'm not able to set breakpoints
the breakpoint gets listed in the breakpoints tab
and the red circle appears
but nothing gets send to the debugger not directly
or over the openocd plugin

Hi Joerg,

I need to create the mcudrv directory if it does not exist... thanks for that...
I have an example project I will commit to SVN, these are the extra debug commands I send to the debugger:

In Project/targets options, debugger, additional commands after connection:

monitor soft_reset_halt
monitor mww 0xFFFFFF00 0x01
monitor reg pc 0x20000000
monitor ARM7_9 sw_bkpts enable
set remote memory-write-packet-size 1024
set remote memory-write-packet-size fixed
set remote memory-read-packet-size 1024
set remote memory-read-packet-size fixed
set remote hardware-watchpoint-limit 2
set remote hardware-breakpoint-limit 2
b main

For an STR7 project.


Hi martin,

I can't find your example project in svn yet.

I'm able to set a breakpoint once or twice
and the program stops as expected.
After that, setting of breakpoints doesn't work any more.
I don't know if gdb usually counts up the breakpoints every time,
but if i delete and set a breakpoint on the same line
I get the following output:

> delete breakpoints 3
> break "D:/Projekte/test-sw/src/MainTask.c:808"
Breakpoint 4 at 0x16c8c: file D:/Projekte/test-sw/src/MainTask.c, line 808.
> delete breakpoints 4
> break "D:/Projekte/test-sw/src/MainTask.c:808"
Breakpoint 5 at 0x16c8c: file D:/Projekte/test-sw/src/MainTask.c, line 808.
> delete breakpoints 5
> break "D:/Projekte/test-sw/src/MainTask.c:808"
Breakpoint 6 at 0x16c8c: file D:/Projekte/test-sw/src/MainTask.c, line 808.
> delete breakpoints 6

As only 2 breakpoints are available when debugging a program in FLASH
maybe the problem lies here?
I use 'monitor arm7_9 force_hw_bkpts enable' after connection.

Did you have a look for the missing tabs in the project/properties window?

I use an older OpenOCD version svn r520 and GDB 6.8.5.
