About this:
3. Reflashing using the USART pins (and ST's Flash Demo Loader application...or the reflash tool provided on Netduino).
1. Are you sure about the ST Flash Loader application? Version 2.5.0 does not support flashing the STM32F0x series. Can you please share a link to the updated tool?
2. About the 'reflash tool provided on Netduino': can you please provide a link to the RTM version of the tool? The last version I tested did not work properly with the Display Module.
Thanks,
