I have made a nRF52810 module according to the reference circuit in datasheet and connect it to my PC via Segger JLink & SWD. Only 1 out of 3 notebook I tried can program the module via nRFgo studio. I tried for a week and still no solution. Can anyone told my how to debug? Thanks a lot!
I tried an Acer win7 notebook & a Lenovo win8 notebook. Both not ok
It is a custom board that just follow the sch in datasheet (even cap values are the same). The osc work properly & both SWDIO & SWCLK pin have signal
