we bought the development kit PNEV7462B.

According to user manual UM10883.pdf we used following configuration

- chapter 3.1: External power supply

- chapter 3.2: VBUS set to 3.3V


Now we can't debug the device. We receive following message

15: Target error from Commit Flash write


When I set VBUS to 5V, it debugging is running.

According to manual, the device should run with 3.3V, or?

What else do I have to do?


Thanks and best regards
