work in progress
set solder jumpers based on this picture (boot0 set to 1, boot1 set to 0):
connect serial adapter (3v3 must have the serious current capability, cp2102 3v3 output is not adequate, or you can use 5V output of adapter and connect it to appropriate pin in place of the USB connector)
then upload the latest firmware using this command:
