This leaves the ROM bootloader active and waiting for a transmit. Then you can go on at your leisure with the stm32loader.</p> <p>Once it's done you press RESET again. </p> http://forums.leaflabs.com/topic.php?id=32&page=2#post-3311 Fri, 07 Jan 2011 04:01:46 +0000 sinneb 3311@http://forums.leaflabs.com/ <p>I used the instructions from the first post to re-flash my Maple v5 with my the FTDI chip from my Arduino Duemilanove. I had to resort to this method when my Maple v5 did not respond at all. No LED's no USB etc.</p> <p>Grab all the tools and build the Maple bootloader</p> <p>Preparing the boards<br /> --------------------<br /> Remove the ATmega168/328 chip from your Arduino Duemilanove to gain full access to the FTDI chip over pins 0 and 1.<br /> Remove all jumpers from the Maple (CHRG, BAT, USB and EXT). This will allow us to power the Maple via VIN from the Arduino 3V3 output.</p> <p>Connecting the boards<br /> ---------------------<br /> Connect Arduino pin 0 (RX) to Maple pin 8 (also RX)<br /> Connect Arduino pin 1 (TX) to Maple pin 7 (also TX)<br /> Connect Arduino GND to Maple GND<br /> do not connect the power yet</p> <p>Re-flashing your Maple<br /> ----------------------<br /> Connect the Arduino to your computer and find the correct serial device (you can use the Arduino IDE for this). Test if the re-flash instruction can find your Arduino:</p> <p><code>./stm32loader.py -p /dev/ttyUSB0 -evw build/maple_boot.bin</code></p> <p>Should give you this error:<br /> Can't init. Ensure that BOOT0 is enabled and reset device</p> <p>Correct! The serial device has been detected and used, but the Maple board is not powered yet.</p> <p>Keep the shell window open and keep pressing the BUT button on your Maple. Connect the 3V3 power from the Arduino to the VIN on the Maple. While still keeping BUT down, rerun the stm32loader instruction in your shell:</p> <p><code>./stm32loader.py -p /dev/ttyUSB0 -evw build/maple_boot.bin</code></p> <p>Output:</p> <pre><code>Bootloader version 22 Chip id</code></pre> ['0x4', '0x10']'<br /> write 256 bytes<br /> ...<br /> read 256 byes<br /> ...<br /> Verification OK`</p> <p>Once the shell starts printing output, you can release the BUT button.</p> <p>When the re-flashing process is done, you can disconnected both boards (from the computer and each other) and place the Maple jumper back over the USB pins. Also refit your ATmega168/328 in its socket on the Arduino Duemilanove.</p> <p>Done! </p> http://forums.leaflabs.com/topic.php?id=32&page=2#post-3274 Fri, 31 Dec 2010 18:57:50 +0000 ianmga 3274@http://forums.leaflabs.com/ <p>Yey!

We tried out something new to clean up the boards before we shipped them. The method didnt get along well with the button rubber. We checked all the buttons (and replaced quite a few) on the boards that went out, but I guess yours slipped by. Sorry! Get in touch with us via email if you need a new button! </p>
