CM4 boot times

Can anyone tell me how long it takes to boot the raspberry compute module 4 with emteria installed on the emmc? I am working on building a device but need fast boot times.

Also is this compute board supported?
I need a small compact board.

    Usually 30-45 seconds, but the very first boot can take longer and have multiple restarts.
    That compute board is not tested, but I would say chances are high that it works out of the box with the CM4 image.

  • Thanks for the info. I’m currently have the cm4 running but it looks like boot times are close to the 45 sec. Can we get this down to sub 30? 30 sec I can deal with 45 is to much.

  • I don't think that's achievable, sorry.
