I have a p5040 processor based demo system.  I installed poky and created images for my development board. I want to modify source code for my u-boot. document says cd <S> and modify the source code.

Use bitbake -e <package-name> | grep ^S= to get value of <S>, the package source code directory. What is this <package-name> ? Please provide any example.


I used bitbake fsl-image-full to generate all images. Documents says , to modify the u-boot, these are the commands .

1. bitbake -c cleansstate u-boot

2. bitbake -c patch u-boot

3. cd <S>


Here, I can skip step 1 and 2, If source code has already been installed.


since I have generated all images for my board, Does that mean I have installed source code and skip the step 1 and 2 ?
