Make px4fmu-v2_default upload does not work on the HK32 on the current master

This for some reason was working but now will not work at all on either of my HK32s.
I tried flashing through Q ground control as well only stable build works.

FMU PWR light green
FMU B/E amber light rapidly flashing.
IO ACT LIGHT constant steady blinking.
The Main led in the top of the board is not on.
No connection to any serial terminal or console.

one HK32 appears to be bricked.

The other will only install stable, nothing else.

Flashing issues with current PX4 master are being investigated here.

This will need to be resolved before the next PX4 stable (v1.7.0) can be released.
