I'm on Mac OS Mountain Lion and I have to put the board into perpetual bootloader mode every time I want to upload a new build. I'm using command line and this happens with the example that's part of the command line doc. when running "make install" after I have already uploaded a program I get this
Install target: flash /Users/jbluepolarbear/libmaple/support/scripts/reset.py && sleep 1 && dfu-util -a1 -d 1EAF:0003 -D build/maple.bin -R Using /dev/tty.usbmodemfd131 as Maple serial port dfu-util - (C) 2007 by OpenMoko Inc. This program is Free Software and has ABSOLUTELY NO WARRANTY No DFU capable USB device found make: *** [install] Error 1
I tried it in the IDE and it can reset the board from there without have to set it into perpetual bootloader mode.
