Do you happen to another Raspberry Pi ? If so, does that SD card boot in that ?
The Geekworm 650 appears to bring out the USB2 OTG interface if you short nRPIBOOT and GND so you could use USB-device boot, boot with the mass-storage-gadget64
https://github.com/raspberrypi/usbboot
This also exports a CDC serial Gadget so it's possible to connect to the virtual serial interface and see if Linux is able to detect the SD-card as /dev/mmcblk0.
Another Pi or PC and a USB cable is all that's required
