Hi there,

I'm using the show_boot_progress function to keep track of the boot process and display errors during the boot on a display (which will be controlled via UART). This works fine for e.g. a bad CRC in the kernel, which will give me a negative progress and I can check, that that is an error. For the Ramdisk on the other hand, there is no show_boot_progress for an invalid ramdisk (see [0]).

So, two questions. 1. There are many places which don't have a show_boot_progress but are a "fail" branch. Can this be done so you can track every (possible) error? 2. Is there a way to "get notified" if the shell opens (e.g. call a callback function), so I can check that (this is usally an error :) )?

Greetings, Marcel
