Ok i’m trying to use OpenOCD within VisualGDB (I don’t think this is a visualGDB thing just yet, short of not being able to upgrade to 0.9.0 just yet). This is with a STM32F103RE (64k RAM, 512KB ROM) I have an image i’m trying to debug. It is offset 0x3000; bringing that up just in case… openocd logs seem to recognize it though, just not working. I can flash the image via the stlink utility, works fine. Any thoughts? Is this something that would improve with 0.9.0?
Command Line:
openocd.exe -f interface/stlink-v2.cfg -f target/stm32f1x_stlink.cfg -c init -c “reset init”
