Posted on November 09, 2017 at 18:32Hello,
the nucleo64p biard user manual DocID030544 Rev 2 tells in chapter 9.4 Embedded ST-LINK/V2-1
The following features are no more supported on ST-LINK/V2-1:
· SWIM interface
· Application voltage lower than 3 V (need to add level shifter to support it)
As the board has level shifters, probably the second point does not apply!
