• PWM ready on pin PB2 (legacy)
• total memory is 1000Mb (disabled all memory reservations for GPU on CLI images)
• support for dual micro SD card version (since v4.5)
• make sure you power the board via power connector otherwise your USB port won’t be powered

Legacy kernel (default branches)

• unstable Bluetooth stack

Mainline kernel (next/dev branches)

• No Mali drivers
• No hardware accelerated video decoding
• Different GPIO numbering compared to the legacy kernel
• schedutil CPU governor may cause clicks and pops on audio output – change to ondemand to work around this issue

Board: Lamobo R1

• b53 switch driver in mainline kernel uses DSA interface for configuration instead of swconfig tool. Please check this issue for details
• underpower issues are possible when using hard drive, HDMI and wireless together. Connecting a battery may help
• Gigabit Ethernet transfer rate is around 300Mbit

Preparation

Make sure you have a good & reliable SD card and a proper power supply. Archives can be uncompressed with 7-Zip on Windows, Keka on OS X and 7z on Linux (apt-get install p7zip-full). RAW images can be written with Etcher (all OS).

Boot

Insert SD card into a slot and power the board. (First) boot (with DHCP) takes up to 35 seconds with a class 10 SD Card and cheapest board.

Login

Login as root on HDMI / serial console or via SSH and use password 1234. You will be prompted to change this password at first login. Next you will be asked to create a normal user account that is sudo enabled (beware of default QWERTY keyboard settings at this stage).
