Common issues and how to resolve them.

Dogebox Hardware not booting

You've turned your NanoPC-T6 dogebox on, but it is just not booting. The SYS LED is constantly on.

We need to perform a boot loader re-initialisation.

WARNING! This will completety erase your current installation and any data that may exist already.

Please make sure you have backups of any important data before continuing.

Prerequisites

• Dogebox
• Power Supply
• Laptop/Desktop host machine to run our recovery commands
• USB cable with USB-C on one end and an appriprate connector for our host machine
• Boot firmware from friendlyelec

Download the RkDevTools for your respective host operating system.

macOs

We recommend using homebrew to manage the dependencies

brew install automake autoconf libusb pkg-config git wget
git clone https://github.com/rockchip-linux/rkdeveloptool
cd rkdeveloptool
autoreconf -i
make
cp rkdeveloptool /opt/homebrew/bin

Connect the machines together

Attach the USB cable to the host machine in an available USB port. Connect the USB-C plug to the front of the Dogebox.

Enter Maskrom mode

The boot loader recovery process starts by putting the dogebox hardware into what is called maskrom mode, this mode allows an attached computer to send commands and updated firmware to the dogebox.

To enter Maskrom mode, hold down the Maskrom button with a pointy tool while plugging in the powersupply. Hold the button down for at leasst 3 seconds after the SYS LED has turned on.

When the button is released the hardware is in Maskrom mode.

mscOS

To verify we're connected correctly to the maskrom mode of the dogebox hardware:

rkdeveloptool ld

This lists the available devices and should show something like:

DevNo=1 Vid=0x2207,Pid=0x350b,LocationID=200 Maskrom

First step is to erase the flash

rkceveloptool ef

then we copy over the boot loader image

sudo rkdeveloptool db MiniLoaderAll.bin

We can then reset the device

rkdeveloptool rd

After this we should be able to load the SD Card into the dogebox and restart the machine.
