The serial console runs at 1500000 baud in the bootloader. When using the standard NixOS aarch64 sd image, set <code>console=ttyS2,1500000n8</code> as kernel option in <code>extlinux/extlinux.conf</code> on the boot partition of the sdimage to get a serial linux console. For debugging, <code>console=uart8250,mmio32,0xff130000</code> should give you an early UART console, before the full serial console is up. | The serial console runs at 1500000 baud in the bootloader.
