I have ccimx6ulsbc dev board with dey-2.2r3 Linux.
I want to modify the kernel settings. I bitbaked kernel menu and saved into new defconfig file, and copied the new defconfig into …/sources/…/linux-dey-4.1/ccimx6ul/ folder to replace the original defconfig.
But what I found is that (After clean and re-bitbake):
The changes into the new defconfig is only in the .config.old, not in the defconfig and .config files under the folder build (./tmp/work/ccimx6ulsbc-…/linux-dey/4.1-r0/build/ )
I also did the following:
- I removed defconfig file from
bitbake raised do_fetch error, defconfig failed to fetch
That confirms the defconfig is used.
- I added a line into the defconfig file. For example, CONFIG_TEST
- clean and bitbake again
The CONFIG_TEST appears in the …/4.1-r0/build/.config_old
but not in the …/4.1-r0/build/.config
I assume .config_old is not what active settings, and .config is the active settings.
So my conclusion is cannot manually editing the defconfig file. Am I right?
If so, how to modify the settings?
