I didn’t exactly solve the problem of OpenOCD not working, but I did find a workaround and I wanted to share it in case it’s helpful to anyone.

I ended up adding a post-build Python script that is set to flash the microcontroller after it’s done building (VisualGDB Project Properties>Custom build steps).

For STM32 you can easily use the STM32Programmer command line interface. Then under the VisualGDB Debug settings just switch Program FLASH memory to Never.

Hey, thanks for the response.

I guess one thing that I forgot to mention is that I have already tried it with a Segger J-Link. It’s been a bit since then so I can’t quite remember what the errors were, but I can give it another shot. On that note, one my coworkers had told me that the J-Link doesn’t work with the STM32H743II. I don’t know if that’s correct or not though.

I’ve also already tried using the ST fork of OpenOCD, but with similar results.

As for STM32CubeIDE, the project I’m working on is one that I’m trying to port from the IAR Arm compiler to gcc-arm-none-eabi with VisualGDB. As far as I know, I can’t easily debug with STM32CubeIDE, but I’d love to know if there is a way.

I’ll take a look on the OpenOCD forum as well to see if there’s anything similar out there.

I managed to figure out the problem. I turns out that the parts of the hex file that are filled with 0x4770BEFF are not actually junk like I thought they were. They’re actually just the default interrupt handlers. My program was hitting some of the handlers and I hadn’t added any thing to tell it where the real handlers were. The solution was just to add the handler names with ‘extern “C”‘ at the top of the file so that the program knew not to use the default interrupt handlers.

I took a look at the log file and the reset command is definately present. Here is a snippet of the log file from when I hit the Reset Embedded Device button:

I also tried running the “mon reset init” command manually and the same thing as before happened. I’ve attached a screenshot below as well as a screenshot of my Debug Settings.
