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:

On debug I get the following error Message:
“Error in final launch sequence

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

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?
Any idea would be helpful

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