Nucleo components:. I have a Nucleo-F446 board that does not work. The measured current draw on the MCU component to be about 15ma. Is it asleep?

See My previous answered question on Merging Nucleo Components. Anyway I had 2 nucleo boards. One had a smoked ST-Link and the other just didn't work. I separated the St-links from both and attached the apparent good st-link to the MCU componet with smoked st-link. It works.

Hooked up the good st-link to the MCU component that didn't work and it still doesn't work. I measured the current draw on the two boards. The good MCU componet draws about 55ma. The bad MCU component draws 15ma. The voltage on the bad MCU VDD pin measures 3.3V.

The error I get from the non-working MCU is that it cannot start GDB Server.

Is the MCU asleep?

Can I wake it up?

Other suggestions??
