PC Engines APU2 Quad Core AMD GX-412TC

Note: AstLinux 1.2.7 or later is required

Note: PC Engines apu2_160307 BIOS is fully functional, though missing ECC support and performance tweaks

Note: For new installations: the PC Engines APU platform will be soon EOL :-(

Serial Console COM Port:

Note -> Skip this section for AstLinux 1.3.0 and later, which uses a 115200 baud rate.

For AstLinux 1.2.10 and earlier, the board type of “genx86_64-serial” defaults to a 19200 baud serial console, unfortunately the PC Engines's BIOS is fixed at 115200 baud, so if you want to view the BIOS console you must change the AstLinux serial console speed to match at 115200 baud. After persistent storage has been configured, from the CLI issue the following command:

setconsole-speed-tty 115200 ttyS0

Tip -> A reboot is required for the change to take effect.

Note: Wake-on-LAN (WOL) does only work on eth2 (next to the USB ports)!
