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.
