ChibiOS Free Embedded RTOS

Dear,

I am using NUCLEO-H743ZI and ChibiOS Studio for testing purpose, i follow the tutorial https://www.playembedded.org/blog/devel ... ibistudio/ for compiling, starting OpenOCD and debugging:

OpenOCD is started properly with the followin message:

"Open On-Chip Debugger 0.10.0+dev-00746-g8f518d359 (2019-03-14-17:18)

"
But when launching debug i have got the following error:

"
symbol-file C:\\ChibiStudio\\chibios191\\demos\\STM32\\RT-STM32H743I-NUCLEO144\\build\\ch.elf
Reading symbols from C:\ChibiStudio\chibios191\demos\STM32\RT-STM32H743I-NUCLEO144\build\ch.elf...done.

You can't do that when your target is `None'
tbreak main

"
Any idea how to solve this default ?

Best regards

What config file are you passing to OpenOCD?

Giovanni

Dear,

When launching Open OCD on STLink i select "stm32h7x.cfg" configuration file

Hi,

Try selecting a script under the /boards directory instead, the one for nucleo H7.

Giovanni,

Sorry for this stupid issue, I found the root cause of the issue, the debug port was not properly configured to be able to communicate with OpenOCD.

Best regards
