Hello.
There is few questions about pl2303 and IDE.
I was successfull flash the firmware to my stm32f103rct6 based board using pl2303 usb converter.
Set the boot0 to 0 and try to connect the board. And nothing happens. IDE wrote only "Disconnected". I try all baud rates. IDE supports PL2303 converter or i must use the board with other converter? Maybe i make a mistake with flashing?

If IDE support this converter and firmware is ok what i need to do to connect this board wiht IDE?
Many thanks.

Whoops...
I'm stupid and forget about one thing. :)
I don't need any converter after flashing. I just connect the board directly to the computer and it's work.
Thank you all :)

:) Glad you found it!

If you powered the device from an external supply (not USB) then I imagine the Espruino console would move back to serial and you'd be able to use the IDE as you were doing (at 9600 baud)

Yes, it should work. Going through the README_* files in GitHub might help.

But basically you just make your own boards/BOARD.py file - and base it in something with a similar chip. IIRC there is already this one: https://github.com/espruino/Espruino/blob/master/boards/OLIMEXINO_STM32_RE.py
