Hi,
The HY32 boards have a Prolific 2303 USB2Serial converter on board that connects to the serial port used by the bootloader. I wonder if it would be feasible to use another Espruino to talk to the serial port behind the 2303 directly to upload a firmware file (now that we have that streaming file access) or tinker with the flash.
Anybody who can say if I could just connect to the TX/RX lines behind the 2303 without frying anything while still being able to talk to the bootloader serial port?
Right now I have really no feeling (or spec) to judge what I can do to those pins and what I shouldn't.
Thanks
Stev
