Newbie here. I have a SEGGER j-link mini and would like to flash Zephyr’s MCUBoot on some xiao nrf52840 modules. Since I only need to connect that one time to flash the new bootloader, I’d like to avoid soldering and de-soldering… Is there a way to connect to the SWD pads without soldering? I saw that there is an expansion board for the XIAO but it seems it also requires soldering the chip on it. Any tips appreciated.
Using this, soldering should not be necessary.
It is quite difficult, but I have also written it in the way shown in the picture in the link below.
