Help with stateviewer

I am having trouble with getting the stateviewer to work with the FreeRTOS. I have a simple test firmware to blink LEDs on the board. It compiles with no error. I am using the following hardware and software: STM32F446RE Microcontroller (M4 with FPU) Eclipse Neon.2 (4.6.2) GNU ARM Plugin WHIS StateViewer Plugin v2.0.10 (Wittenstein High Integrity Systems) openOCD v0.10.0 FreeRTOS v9 STM32 HAL library my GDB OpenOCD debug console as follows: “Open On-Chip Debugger 0.10.0 Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html Info : The selected transport took over low-level target control.

The program is not being run.” My best guess its to do with the stateviewer, everything worked before that. So its something with the stateviewer FreeRTOS settings: configQUEUEREGISTRYSIZE 10 configUSETRACEFACILITY 1 openOCD.cfg added “$_TARGETNAME configure -rtos auto”, It does auto detect the FreeRTOS correctly as seen above. Anyidea would be helpful Thanks Greg

I got that figure from the forums over GNU arm plugin. I do have a rtos question now.. when I debug … Error: Error: null stack pointer in thread Error: RTOS: failed to get register list Error reading stack frame from FreeRTOS thread Whats causing these errors?

Sorry – no idea – those errors are not coming from the RTOS.
