Me again … So I gave up on serial to the STM32F3Discovery board (for now) and moved on to the NRF52 board that I just got.
Started working through the tutorial http://mynewt.apache.org/os/tutorials/bletiny_project/ <http://mynewt.apache.org/os/tutorials/bletiny_project/> and, of course, found some issues. :-) I can load the image on the board, and it appears to be running (can’t see the BLE device using a BLE stumbler, but that’s another issue I guess) and … still no serial access. From what I know from the board specs, pin PA.08 is RX and pin PA.06 is TX, so I hooked those up to my AdaFruit FT232H board, which should give me USB-Serial interface and … once again, nothing. Hmmm … could it be the FT232H itself? Hooked the PA.08 and PA.06 pins to my scope and I would expect to see activity on the PA.06 pin but nope! Flat-lined. So I’d love to be told the error of my ways here … dg -- David G.
