I have got the latest firmware for the R410 from Ublox and want to load to load into the R410 on the boron. I have successfully upgraded other (non particle) R410’s that I work with.
To upgrade the modem firmware you need access to the R410’s USB port and the USB_Detect pin. I see on the schematic that these pins are available as test points. Is there some documentation showing where these are located on the board?
