Hi
I've built a tool chain based on gcc, openOCD and Eclipse as IDE.
After a few adjustments (
) I was able to connect to the STM32 through ST-link/V2 and to flash a simple "blink program" into it.
As a next step, I wanted to flash (and therefore be able to debug) what is normally loaded as Axoloti's firmware.
That is, the content of the 'Axoloti/app/firmware' folder.
I also copied the chibios and CMSIS folders to be part of the Eclipse project.
The code analyzer gives me quite a bit of unresolved references, but I decided to build (after changing some references in the makefile) and the process went through with no errors.
However, when I launch the debugger, I get a
undefined debug reason 7 - target needs reset
target state: halted
target halted due to debug-request, current mode: Thread target state: halted
xPSR: 0x01000000 pc: 0x080699a0 msp; 0x20000200
target state: halted
target halted due to debug-request, current mode: Thread
xPSR: 0x01000000 pc: 0x080699a0 msp: 0x20000200
Error: Memory write failure!
type of error, and the application (again, a simple blinking program) does not start.
I set ./bin/obj/main.o as the application to debug...is this correct?
I have no experience with this but I noticed that the simple blinking example makefile has a main.out as output, and this is what is targeted by the debugger in that case.
I can imagine that this can easily go wrong with changes of base addresses and what not...all stuff I still have to dig into and understand...So I'd be grateful if anybody would give me few hints about how to proceed.
Thank you in advance,
Michele
