Hi, can anyone indicate to me the physical location of bridge (0 Ohm resistor) R31 on the PCB of the BPI-M4? I have the DXF files, but cannot see any component labels. R31 is in the nRST line of the eMMC, and I want to add a switch that allows to enable/disable the eMMC so I can choose to boot from µSD even when then eMMC has a bootloader.
