Hi folks I've tried it with new cables each one is 5cm long has the same displayed again when I measure the volt number comes out the following:
VCC pin: 3.2 v
SWDIO: 2,3 v
SWCLK: 3.2 v
GND: 3.2 v
NRST: 3.2 v
on the cable it is not at Jlink it shows the following values when measuring:
VCC pin: 3.2 v
SWDIO: 2.89 v
SWCLK: 2.89 v
GND: 3.2 v
NRST: 3.2 v
everything is fine there or is it on jlink I can not remember the connections to the board I think it can not be
