A week or so ago someone was trying to start a QMX using a current-limited bench power supply.? He chose his amperage limit appropriately, 250 mA if I recall correctly, but his voltage setting was 5.6 volts.?? Hans suggested upping that to 6 volts so the microprocessor could get the SMPS switch mode power supplies enabled.? I believe that fixed the immediate problem.? His build had several problems so at that time he said his board was dead.
