Quick boot on Raspberry for embedded application

(1/9) > >>

Hi
I need to noticeably reduce the boot time on a Raspberry for an embedded application.

Everything I have found seems to require compiling scaled-down linux versions, buildroot, yocto, void linux, OpenWRT, Poky.

Anyone with experience in the field?

I just need Wifi and the UART. If there was an .img file to create the SD, all the better, because it is complex for me to have to compile and it can take hours before it does not work.

What would be the maximum boot time allowed?

All you need is to edit the file which describes the services to be launched.
Less services, less time to boot. Easy job.
Wifi requires more stuff than the simple Ethernet.

10 seconds.
