    I'm sorry to bother you, but now I have the same problem as you. My NRF52840 uses 1.8V voltage, which means that the voltage of my SWDIO SWDCLK is 1.8V. And my Jlink is 3.3V, could you please tell me how to solve this problem so that JLink can work normally and download the program to NRF52840 successfully through Jlink?Looking forward to your reply. Thank you
