Advanced users • Re: What's taking 9 seconds before Linux begins to boot (CM5 with eMMC)

I do not want to come across as someone trying to tell the developers how to do their job, and I fully recognize that a lot of work has already gone into this. However, since the CM5 is being positioned strongly for industrial use, that initial boot delay is a much bigger issue than it might seem. In many industrial environments, the system needs to be operational almost immediately. Boot time is not a convenience feature, it is often a hard requirement.
Yes. The 8~10 second bootloader is too slow. A splash screen that displays while the bootloader is running would give operators less anxiety for 10 seconds as they wonder if anything's working.
Custom minimal linux images will help, only include stuff you need.
I've done that. For my project, after the bootloader runs, the kernel, userspace, and application come up in about 6 seconds. That makes boot time a total of about 16 seconds with 60% of that being the bootloader. It's odd that the boot time for the entire system is so dominated by the bootloader.

EDIT:
For comparison, here's a video of an ARM Windows CE Panel PC booting in just 5 seconds, and this device is almost a decade old, and far less capable hardware.
