Hi,
I am able to program a SparkFun nRF52 breakout board via nrf52 Dev Kit using Segger Embedded Studio. However, I am not able to achieve the same results using nrfjprog. All the dev tools are OSX.
A simple erase all using nrfjprog returns the below errors in log file
FUNCTION: open_dll. FUNCTION: open_dll. . . . Device "NRF52832_XXAA" selected. FUNCTION: read_device_version. FUNCTION: read_device_version. JLinkARM.dll CORESIGHT_WriteAPDPReg returned error -1. JLinkARM.dll CORESIGHT_WriteAPDPReg returned error -102. FUNCTION: close_dll. FUNCTION: close_dll.
What I am missing here? Anything different to do when using command line tools?
