-The build process builds the root filesystem of the device as into the kernel as an initramfs. The initramfs is never unmounted and contains the full userland, including all binaries and libraries. The FAT32 partition is mounted under `/mnt`. On boot, a serial terminal is started on ttyS0 and can be accessed via the UART header on the board (see above). On startup, init starts the dumper process which keeps running until the console is switched off. The dumper communicates with the WT51F104S MCU connected to the cartridge port via ttyS2 and executes shell commands. The program flow looks like this:
