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)

@Gordon i have one more question.
Can i upload Espruino firmware to STM32F103RET6 chip that have 512k ROM.
Espruino compatible with this chip? How can i use all of this 512k of ROM if it compatible?

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

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

> Quote text by starting lines with >

For syntax highlighting, surround the code block with three backticks:

```
Your code goes here
```
Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
