Inspecting the initramfs
This page explains how to connect to your device when it has booted to the initramfs by installing the debug-shell hook. This is useful if you want to know more about the boot process, simply inspect the initramfs or if you want to debug why something doesn't work.
It is possible to enable a telnet daemon that gives you a shell this way:
$ pmbootstrap initfs hook_add debug-shell $ pmbootstrap flasher boot # or however you flash/boot the kernel (wait until the device booted up and you are connected to it) $ telnet 172.16.42.1 Trying 172.16.42.1... Connected to 172.16.42.1. Escape character is '^]'. Type 'pmos_continue_boot' to continue booting: # echo "hello world" hello world # pmos_continue_boot Connection closed by foreign host.
If the telnet command does not work out of the box, read connect via USB Networking in the Initramfs.
