How to integrate Driver in U-Boot

[nikhil29]

Hello NXP TechSupport

I'm working on Custom Board which is based on i.MX 8M Mini Processor.

1] I need to integrate the Driver in U-Boot and Compile it to build its image.

2] Can you please share the detailed procedure step by step.

Thanks

Hi

The key file is

/drivers/Kconfig

/drivers/Makefile

Then you can research the example driver:/drivers/ timer

Hello Zhiming, Thanks for your time

1] I have written Makefile and Kconfig for integrating driver.

2] After that to bind that driver with the bootloader, I used the command,

bitbake -c menuconfig virtual/bootloader, but showing error

ERROR:-

Please provide a resulting solution for successful driver integration.
