To be fair, bricking your maple this way is rare, and its not really bricked 'permanently'. Also, the library issue that caused your maple to become bricked has since been fixed ;) svn update! importer on "How-To Unbrick Your Maple" http://forums.leaflabs.com/topic.php?id=19#post-85 Sat, 03 Apr 2010 14:55:50 +0000 importer 85@http://forums.leaflabs.com/ [on Thu 07 of Jan., 2010 02:38 EST, by zhanx] If your like me you forget things. and once in a while its not go to forget them. It may result in a few issues. Like you uploaded something to the Flash and now it don't work right. This is done on ubuntu using the lastest svn (95) Navigate to here: */leaflabs-read-only/trunk/library/src edit your main.cpp here is the default setup for the file int ledPin = 13; int toggle=0; void setup() { pinMode(ledPin,OUTPUT); } void loop() { digitalWrite(ledPin,HIGH); delay(200); digitalWrite(ledPin,LOW); delay(200); } int main(void) { init(); setup(); while (1) { loop(); } return 0; } Which is the blinky program. I included it so you can undo any changes that you may have made. the rest needs to be ran in the terminal. make sure your path is : ~/leaflabs-read-only/trunk/library$ $make clean $make LINKER=lanchon-stm32-user-rom.ld DEFFLAGS=VECT_TAB_ROM The next command get ready but dont hit enter yet: $sudo make programFlash unplug your board plug it in. Notice the series of flashes? 5 fast, 3 slow. On the second slow blink hit enter. This is what you should see: ~/leaflabs-read-only/trunk/library$ sudo make programFlash dfu-util -a1 -d 0110:1001 -D build/main.bin -R dfu-util - (C) 2007-2008 by OpenMoko Inc.
