Hello,
I did developed custom board with Nrf52810 and now I have problem with flashing the chip.
I'm trying to make the programming with ST-LINKv2 with SWD and using Arduino IDE.
The connection is good, because I don't get any errors and when I upload the code everything seams to be ok. But after that the chip did nothing, like nothing. I try with couple of codes and even simple examples like LED blinking are not working. Like the program was never write to the chip.
Here is the log from the console.
Sketch uses 2104 bytes (0%) of program storage space. Maximum is 409600 bytes.

I did reflash the programmer with latest ST firmware and still nothing.
Please for advises how can I resolve this problem and make it working with ST-Link V2. I do find that other programmers like J-Link will work better and maybe that is the solutions, but it's too expensive and the cheaper alternatives are out of stock everywhere, so I can't get one sooner.
