This evening I upgraded a Boron from firmware 1.4 to 1.5 and have run into difficulty with mirrorTo
The final system is built into an enclosure and the onboard RGB led is not visible. I use mirrorTo to display and led signalling to display status.
SInce I want the system modes to be displayed during startup and DFU mode I enable this function using mirrorTo(D2,D3,D4,true,true) in a STARTUP void.
This was working fine under 1.4 but does not work under 1.5 - the external RGB led only shows status when in Safe mode (magenta) and DFU mode (yellow). The leds are off in normal operation.
I have not found any clues by searching the bulletin board and have yet to revert to 1.4 but am interested to know if this is a known problem with 1.5?
