Hello. I'm relativly new with Chibios. I've downloaded the Chibios 3.0. from the site, and I'm developing my custom application. My code works fine, but when I try to debug it, the openocd cannot detect ChibiOS, and when I set a breakpoint into a task, the software running does not stop, when hit the breakpoint.
I'm running Ubuntu with Eclipse Mars ide.
I configured the openocd, and the Eclipse by this tutorial:
http://vedder.se/2012/12/debugging-the- ... d-eclipse/My openocd config file is the following
Code: Select all
source [find interface/stlink-v2.cfg]
source [find target/stm32f4x.cfg]
$_TARGETNAME configure -rtos ChibiOS
reset_config srst_only srst_nogate
The openocd works fine with a non chibios based software, but when i connect to the openocd it show the following:
Code: Select all

I've tried to set the config file to -rtos auto but doesnt helped. I also triple checked my .elf file contains the ch_debug symbol!!!
But my main problem is, why does not stop the software running, when i set a breakpoint inside a thread? Until i put it into the main sequnce (initialisaion) it works, but noting in the thread.
I put here my main.c code, the main loop does nothing, just sleep.
Code: Select all
/*
* Application entry point.
*/
int main(void) {
/******************************************************************************/
/* @Description : Initialization of Chibios subsystems. */
/******************************************************************************/
vidInitSubSys();
chThdSleepMilliseconds(1000);
/******************************************************************************/
/* @Description : Initialization of user applications. */
/******************************************************************************/
vidInitApplications();
/*
* Normal main() thread activity, in this demo it does nothing except
* sleeping in a loop and check the button state.
*/
while (true) {
chThdSleepMilliseconds(500);
}
}
Any idea??
The code looks unreliable
