IoT Router Carrier Board Mini FAQ【DFR0767】

Q1:Using USB-C to connect to PC to burn image, the device cannot be recognized.

A1:Please check if the USB cable supports data transfer, some of the power-only USB cables are not connected to the data pins

The hardware is not currently compatible with native USB-C to USB-C connections, please use a USB-A to USB-C cable to connect to your computer

Q2:Raspberry Pi OS install r8168-dkms report ERROR.

A2:Some versions of the Raspberry Pi OS kernel do not support the installation of r8168-dkms. We recommend using Ubuntu Server, which has been tested to install.

Download Ubuntu Server For Raspberry Pi at (https://ubuntu.com/download/raspberry-pi)

Q3:The ETH does not work after you download the provided Openwrt system.

A3:The new version of CM4 runs a new firmware that is not included in any of the widely available OpenWRT releases.

Swapping out the .dat and .elf firmware files on the FAT32 boot partition, w/ the latest firmware files from RPi GitHub (https://github.com/raspberrypi/rpi-firmware) made it work.

Thanks to Mr. M for discovering the problem and providing us with a solution.
