Hello,
I have worked with a few nrf9160 and I use nrf connect and a J-link.
It is expansive but it always work.
Now I have the nrf9151 is there a way to program the nrf9151 feather with the j-link?
If I few the schematics the SWD pads are removed.
I use windows so it is a bit of a headage to get zephyr tools extension working.
