The serial cable (that ordinarily connects to the LCD controller) has four wires: Red, White, Green, Black.
- Red ➙ Ground
- White ➙ TX USART1 - pin 42†
- Green ➙ RX USART1 - pin 43†
- Black ➙ +3.3V (yup, they're backwards)
†: on the STM32 processor

In this example I'm installing Tails to the internal storage of an ASUS Chromebook C302 with mrchromebox's EFI firmware. The steps should be the same for any Tails-supported EFI computer.
My internal disk is mmcblk0
and its first partition is mmcblk0p1
and my Tails USB drive is sda
and its first partition is sda1
. Yours may differ, so substitue appropriately.
The Tails installer doesn't seem to want to install to internal storage even though mine's recognized as an SD card.
Boot Tails as normal but set a root password in "Additional Settings".
Launch "Root Terminal".
Create partitions on internal storage with the same geometry as the Tails partitions.
