Hi there, in order to get the booting more robust I already changed autoboot_abort_key from "any" to "ctrl-c". We wan't to keep the autoboot_timeout to be able to access the bootloader prompt manually or with install tools more reliably to a non zero positive value. I.e. enter prompt with timeout greater than zero still should be possible. Is there a mechanism already implemented or thinkable to be added as a command, which boots when the prompt is idling for a couple of minutes? Lets say the bootloader caught ctrl-c by accident (free serial pins in headless encasing in rough EMV environment) and idles there for years...
