RE: NRF51822 programming with uVision and ST-link

I can do a full chip erase in uVision before the programming. It seems to complete that successfully, but then says "Programming failed!", followed by the 'Flash download failed' error as before.

EDIT: Okay, got it working! For anyone else that experiences this problem... All it seems I had to do was update my programming algorithm in the debugger menu. Seemed to do the trick when I switched it to "nrf51xxx External Connectivity Board". I changed to that, set it up to do a full chip erase, managed to program it a few times.

I then switched back to the original programming algorithm and put the other settings back the way I had them before too, seems to still be working.

nRFGo only supports J-Link nothing else. Search for ST-Link on this forum there are a few threads about it. An other alternative is to use the IDAP-Link here.
