Since getting my Espruino board the STM32F3 discovery board has been gathering dust! I pulled it out and am trying to update to the latest software. I don't seem to be able to find boot1 and boot0 on the board. Does the STM32F3 have a different procedure to enter boot loader then other boards?

Nope! Just the same - but because it's got a separate programmer on the board as well it's better to use that. Just follow the instructions here: http://www.espruino.com/Other+Boards

@Andrey:
Did you see this note (from here: http://www.espruino.com/Other+Boards):

"Note: This board is more difficult to connect to. You need to power
up the board without 'USB USER' plugged in, and then plug in USB
later. If you subsequently reset the board, you'll need to unplug USB
and plug it back in."

You need to use the "other" USB connector (USB_USER) and not the one you used to upload the Espruino software.
Maybe that is the issue you are running into?
But reading your note again, you probably already tried that.

@mikewop: you are right, I tryed, and everything was ok on previous versions.

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

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

Just like Github, a blank line must precede a code block.
