I installed nRFgo Studio Version 1.20.0.2 (which removed my older version) and was trying to program a softdevice (5.2.1) into our custom board and was presented with a popup window which stated "Softdevice: s110_nrf52822_5.2.1_softdevice.hex programming failed: Invalid parameter error.
What is the deal. So I then removed nRFgo 1.20.0.2 and reinstalled 1.17. 1.17 now has nRF5x Programming grayed out.
