In my application, I am using FreeRTOS underlying CMSIS-RTOS API. I am facing two issues related to RTOS and interrupts while debugging. whenever I start debuggig my application, debugger alaway go to interrupt hence I can not step in or step over other functions. I want to some how mask interrupt before step in and after stepping in, interrupt should be unmasked so that my application works properly. I read some post where it suggested to give a command
cortex_m maskisr auto
but it gives me error while debudding.
Error in final launch sequence Failed to execute MI command: cortex_m maskisr auto Error message from debugger back end: Undefined command: "cortex_m".
I have written this command in Debug Configuration > Startups > Run Commands dialog box.
The second issue is, I want to make openOCD FreeRTOS aware. I have followed a blogpost and made a change in the script stm32f7xx.cfg. (this script is at location “C:\Ac6\SystemWorkbench\plugins\fr.ac6.mcu.debug_188.8.131.52902141520\resources\openocd\st_scripts\target”). So, I wrote in that script.
$_TARGETNAME -rtos auto configure -work-area-phys 0x20000000 -work-area-size $_WORKAREASIZE -work-area-backup 0
But I am getting an error
Error: invalid subcommand "-rtos auto configure -work-area-phys 0x20000000 -work-area-size 0x8000 -work-area-backup 0" in procedure 'script' at file "embedded:startup.tcl", line 60 at file "comm_card_2 Debug.cfg", line 29 in procedure 'STM32F746ZGTx.cpu' called at file "C:/Ac6/SystemWorkbench/plugins/fr.ac6.mcu.debug_184.108.40.206902141520/resources/openocd/st_scripts/target/stm32f7x.cfg", line 68
can anyone please tell me how to resolve these issues?
I am using:
openOCD(for 32bits Windows) version: 1.22.0.xxx System Workbench for STM32 - C/C++ Embedded Development Tools for MCU Version: 220.127.116.11903050911 Eclipse GDB Hardware Debugging Version: 18.104.22.168704050430 System Workbench for STM32 - C/C++ Debugging Tools for MCU Version: 22.214.171.124902141520 MCU: STM32F746ZGTx (Arm Cortex-M7) Board: NUCLEO-F746ZG
Thanks in advance
