How to get a custom minimal kernel configuration

[leocheng]

Hello,

I need to get a minimal kernel runing on an embedded hardware. The machine cpu is NXP i.MX7, it should support,
I2C
USB device for micro SD Card MSD mode
micro SD card, FAT file system
4.7 LCD with LCDIF
power management
video camera with MIPI DSI
matrix keypad
GPIO
ADC
PWM

The system is set up to run qt program after power up. So I want to get a clean and minimal kernel configuration, only includes above sutffs, no network, no wifi, no bluetooth, etc, just keep the kernel as small as possible.

Can anyone having the same experience how to make it.

Hi Leo

one can start with core-image-minimal configuration described

in Table 1. Freescale Yocto project images attached Yocto Guide.

Then include or exclude necessary modules using its description

in Linux Manual.

Best regards
igor
