Hello- I am trying to program a custom nRF51822 board with a J-Link-lite. From the J-Link-lite, I am using the 10-pin header and have it wired like this: I'm using pins 1 (VCC, 3.3), 5 (GND), 2 (SWDIO) and 4 (SWCLK) which are connected to same on my board (ie: SWCLK is connected to SWCLK). I have followed directions given in some threads with similar questions, but still get the "Error: Flash Download failed - "Cortex-M0" I have the nRF51822_S110 selected (it is the only option) and have the correct algorithm selected as well.
Any help would be appreciated. I am stuck.
