So compiling the firmware went ok as ling as i iised arm-none-eabi versions below 10, and removed werror from makefile. But and unfortunatly did not check before flashing, the uart vcc pin has no voltage even after enabling tpower. The schematic shows that the vcc is connected thru a 0ohm (r15) resistor to 3.3v , but r15 is unpopulated,and one side has 3.3v the other side goes to the uart vcc pin and the two sided are not connected. i at first figured the resistor fell off but the pics of jeff probe on-line also have it unpopulated...How exactly am i supposed to enable the 3.3v on the uart vcc pin? Is it working for other people? If a digital switch is involved then schematics should be updated, if not how would it get power from an unpopulated r15...what the hell is going on? Does a manual exist to explain this? Also how is the 1.8v to 5v stuff set? Only automatically based on adc readings?
