Hello,
I'm trying to program my custom board with a PCA10056 following this scheme (Note that my custom board is powered by the PCA10056) :
VDD (PCA10056) ---> VTG(PCA10056)
VDD (PCA10056) ---> VDD (CustomBoard)
GND (PCA10056) ---> GND (CustomBoard)
GND (PCA10056) ---> GND Detect (PCA100056)
SWD IO (PCA10056) ---> SWD IO (CustomBoard)
SWD CLK (PCA10056) ---> SWD CLK (CustomBoard)
I'm able to erase my custom board and connect to it but I can't program the flash ... When I try to program the softdevice the I got a ''verification fail''. But after that my flash memory seems to have 2 region like that:
The voltage on my custom board is good (2.96V, the same as the PCA10056) and I have already done a recover but no effect. Here's the result:
nrfjprog --recover -f nrf52
Recovering device. This operation might take 30s.
Erasing user code and UICR flash areas.
I don't know what I can test now ... Could anyone help me ?
Kind regards,
Sylvain.
