How to debug with Android on Rock 5B?

#1

Hi,

I tried to connect Rock 5B to my computer, but seems the current is too high, the board reboots randomly.Is there any way to provide extra power, or use another port to debug with adb?

Thanks,

There are people using Raspberry Pi as an USB accessory faced similar issue and they end up with something like this:

This is called an USB-C Data/Power Splitter and is available as a Pi accessory in some Pi Shops. You can use this to connect the device to your computer for debugging and supply an extra power source. The one in this picture even has a DC power jack that you can connect a dumb DC power supply to overcome the PD issue.

If I were to connect a dumb 12V supply and a usb-c-flash to the extra port, will the usb-c-flash be powered with 12V?

A lot of these boards include pull up/pull down resistors so that it can only be used with 5V power supplies to prevent damage because raspberry pis are powered exclusively with 5V. This could be good enough for OP’s case (debugging with ADB) but probably not for your use case if you need to run it at higher voltage.

Thank you. I fix this with debugging over network. For the vast majority of people, this is probably the most feasible approach. Because these adapters are hard to come by.
