Question on using external kernel source

according to UG1144:

petalinux-config:

a. using external kernel source;

b. fill the absolute path of source code, 

then petalinux-build, OK.

however, then I remove the build and images dirs, and make some sytax error in a driver source code on purpose, the petalinux-build still give a success result with a new images dir generated.

why is it? thank you.

Re: Question on using external kernel source

Re: Question on using external kernel source

I tried re-build it after petalinux-build -x mrproper and removing build dir, however there were no changes.

I noticed that the build info shows there are some task needn't be rerun, any connections?

Re: Question on using external kernel source

Hi

Looks like peta-linux build is taking old directory instead of new directory which you have changed

Make sure, there are set of chages to Build system after you modify the source path,

check the time stamp of build w..r.t to Makefile generation, it gives exact difference in Build changes

 

Provide Kudos if this post is helpful.

Thanks & Regards
