Hi,
I have MCU based on Cortex-M0. While developing bootloader i left code which disables SWDIO by mistake. Now i can not get access to MCU. It starts and immediately disables SWDIO.
1. I can not use RESET pin, reset function seems disabled by default on this MCU. Tried pull up/down but it always starts.
2. I can not attach debugger before MCU disables SWDIO. Seems not enough time.
Any suggestions how to get access to this MCU ?
