I have a Value Line Discovery board - STM32F100RB and three of the outputs are connected to a 3v3 converter to get a 5v output. I have tried another controller board with 3v3 outputs to drive the convertor board and I get a clean signal. (Either 0 or...

I have a DiscoveryVL card (STM32F100RB) and I want to use pins A13 & A14. The manual says I have to unsolder some jumpers on the back to use these as GPIO but then SWD won't be available. I have been using the ST-LINK utility program via a USB cable ...
