The STM32-H103 has a nice form factor of 61 x 34mm (2.4 x 1.3"). The right board if you need something more slim than a Maple with more pins broken out than the Maple Mini.
I've added a small wiki entry on how to program the board via the STM32 embedded serial boot loader if you don't happen to have a JTAG at hand.

Those are environment variables, I use the unix toolchain and set the variables in my shell session.
Do you use the IDE? the support for this board into libmaple got included after the 0.0.12 release.
One can patch in the missing board specific files into the IDE (and edit a couple of other files...), if you don't know how to go about it I can come up with a patch for you
Depending on your OS, I'd rather recommend to use the unix toolchain with the most recent version of libmaple from github, no patching required ;-)

Yes, unfortunately I am using the latest IDE on Windows. I recently moved up to Maple from Arduino. I was hoping to write the processing style code in the Maple IDE, compile and then upload the resulting binary file with a FTDI using the python Serial script.
I was hoping it would be as simple as adding a few lines in the boards.txt file to get the binary output file which could be loaded via the built in bootloader.
This might help you: http://static.leaflabs.com/pub/leaflabs/maple-docs/snapshots/2012-09-04/unix-toolchain-win-setup.html#unix-toolchain-win-setup
I've tried to patch in the olimex_stm32_h103 specific files into the IDE. Blinky has compiled successfully, but I have no access right now to the board so could not upload and test it.
p.s. another possibility to use the unix tool chain on windows is to install cygwin and just pretend to be a unix ;-) I'll put than in another wiki page.

Guys, I hope I can save you some trouble. When I added libmaple support for the STM32_H103 board, I also hacked the libmaple bootloader to run on this board. I just didnt get to uploading it, but now you find the code in my github branch:
https://github.com/torfbolt/maple-bootloader/tree/olimex_stm32_h103
You can just flash it via JTAG (or maybe the embedded serial boot loader) and then upload your programs via DFU. I haven't tested the Maple IDE, but the board should behave like any other Maple.
You must log in to post.
