i.MX8: How to bring up minimal image with boot time on i.MX8MQ.

[vipulkumar1]

Hi,

I want to bring up i.MX8MQ with minimal console image including only serial driver for debugging with boot time if possible 1 - 2 seconds only. Don't need any other driver/ feature/software as of now. Can you please guide me with the steps & kernel/boot configuration changes required to achieve the same.

Thanks & Regards,

Vipul Kumar

Hello @vipulkumar1 

I hope you are doing very well.

You can try compiling the core-image-minimal following the Yocto User's Guide.

You can see that image just allows the device to boot.

If you need to make optimization for boot time, please take a look to the AN14093 (Fast Boot on i.MX 8 and i.MX 9 Using Falcon Mode and Kernel Optimizations)

Best regards,

Salas.
