I'm fairly new to the Rock64 boards and recently decided it would be fun to play around with one. I bought the 2GB RAM version plus 16GB eMMC and power adapter. I used Etcher to flash ayufan's minimal artful arm64 image which worked great! It booted and I plugged in the network and was able to shell in just fine. I ran into problems, however, when I attempted to attach this GPS board to it: https://store.uputronics.com/index.php?r...duct_id=81. After plugging it all in I can see that the GPS board powers up just fine and even acquires a GPS signal and starts the TIMEPULSE LED going...BUT the main board doesn't boot. The white power LED is on and the red standby LED is solid with the green LED on the left side of the ethernet jack on but it doesn't appear to actually boot at all. Any suggestions?
Note: my first thought was that the expansion board could be drawing too much power but I looked at the spec sheet for the ublox MAX-8Q and it only draws up to a max of 65mA. The power supply supposedly outputs up to 3000mA which I can only imagine should be sufficient. The expansion board is designed for any of the Raspberry Pi+ models and when I look at the traces from the ublox chip to the header on the GPS board it seems that the pins do match up where they should.
