failed to start debuuging on STM32F0308-Discovery board
Here are little more brief about the issue.
I had done the exact same procedure for another board of STM32F0Discovery, which using microcontroller of STM32F051R8, instead of STM32F030R8T6.
All debugging launching is fine, has no problem.
Previously when I play OpenOCD from command, I have similar experience. The board of STM32F0Discovery runs fine, but STM32F0308-Discovery runs into failed. However, by upgrade OpenOCD from 9.xx to 10.xx, I got rid of the problem, both board works fine.
I checked the version of OpenOCD, the latest one with SW4STM, or Ac6, it is v10.xx, so I was confused.
By my understanding, this more like a little problem on STM32F0308-Discovery, either on the built-in ST-Link, or the debugging core within STM32F030R8T6. But some workaround in OpenOCD config file should be able to fix this.
Could someone help? Please.
