Suppose I wish to try out a simple change to one of the drivers to see what it does, what is the preferred way to do so.
Example: intel_mid_ssp_spi.c file, I would like to try changing where it clamps the divide to a minimum of 3 to 2 to see if I then get 8mhz...
Do you make the changes in this generated file (build/tmp/work/edison-poky-linux.linux-yocto/....
or do you make the file in the file that generated it:
I assume probably the patch file. (likewise if I wish to turn on debug support?)
Now after I bitbake the stuff. Do I need to install a whole image, or is there a simple way to just replace and/or override a driver.
Note: I have already have done a successful bitbake of the unmodified latest edison-src. I have not yet gone through the process of actually installing it and running it.
Sorry if these are obvious questions, I have not gone through the process of changing a linux kernel before.
I'd recommend writing an own patch file and include at the end in the kernel bitbake recipe
