Yocto U-Boot modification

Hi everyone,


Recently, We've received my custom i.MX6 board based on SabreSD and struggling with board bring-up.

We've decided to use Yocto to build everything (u-boot, initramfs, kernel) for MfgTool. (I'm very new to this)

I've downloaded sources for the dizzy release and built images with fsl-image-mfgtool-initramfs for mx6qsabresd.


Now I need to make some modificiations (such as, changing SPI CS pin, adjusting some voltages of PMIC, etc) in U-Boot and re-built the image.

I have modified the source code;




and run the bitbake command


$: bitbake u-boot-imx-mfgtool -c compile


But basically it says that nothing has changed and out of xxx number of tasks, no task needed to be run.


I'm not sure if what I did is a correct way of doing this. Any help is appreciated.


Thanks in advance.
