Notes

Known Issues:

Problem 1:

Flashing the chip using "st-flash --format ihex write serial.hex" works fine, but the program fails to run when the MCU is reset.

Solution:

TBD Possible leads: BOOT0 configuration

Problem 2:

Discovered odd behavior when flashing new programs to the MCU. I.e - RXNE register wasn't getting set even though UART data was being transmitted to the MCU.

Solution:

Perform a hardware reset (button if your board has it) before flashing the MCU.
