I did not see a backlight without BLVDD or BLGND connected. Possibly
this depends on the 3.3V current provided by the board? Obvious
connections would be J18 pins 2 and 4.

is very similar to the NSH configuration with support for the FTDI

I have seen issues also where the board does not recover after a
reset. It required a full power cycle to get functionality back.
It might be necessary to reset the FT80x during initialization.
This is not too surprising since there is no reset signal to the
FT80x (there is power down/up). It might be necessary to perform
a software reset of the FT80x during initialization.
1028-03-10: Most of issues have been worked out in the FT80x demos
and the driver appears 100% functional.
