Dear ladies and gentlemen,
There is not much information about the RESET pin in the datasheet. I guess, it doesn't have an internal pull-down resistor, but when I look at...
Hi,
I have a problem configuring readback protection using boot.
It seams that the BOOTLOADER stops when trying to read some information from the softdevice if readback...
