Hello guys!
Does anyone know how to connect a 5V step-up converter to the board to charge the USB? I am using a 3.7V 3000mAh battery, with a step-up converter to 5V.

I will tell you what is working so far. I connect the PWR cable, the USB powers up, I connect the battery, I attach the Step-Up converter's output to the Capacitor (C76), I detach the PWR cable and it works perfectly!
But if I just put the battery and start the system, it won't power up the USB.
How do I connect it to work immediately without a power cable?


Hi Landoro,

could you please write down the following information:

- Kernel version
- bootloader
- are there any differences in boot messages?
