[yocto] Debugging a build issue in an isolated enviroment

[Alan Martinovic]

Thanks for the suggestions
Am currently implementing both of them and am trying to understand how the
patching is done.

In the temp directory I can see all the tasks.
For some reasons the patch wasn't applied correctly and I'm debugging why.

I have patches from before which are being correctly applied, one of them
being "0001-sun8i-configs-Add-CONFIG_BOOTCOUNT_LIMIT-ENV-for-men.patch".
Am using that one just as a reference for this example.
I want to see the steps done to apply the patch so I do:

    temp$ grep -r 0001-sun8i-configs *
    temp$ grep -r quilt *

I am expecting to see some commands related to the patching process in one
of the run scripts.
For example,  "quilt" followed by some arguments or
"0001-sun8i-configs-Add-CONFIG_BOOTCOUNT_LIMIT-ENV-for-men.patch" being
applied
by some other tool instead of quilt.

I only end up with some findings in the log files (log.do_fetch,
log.do_unpack which don't tell me much).


Where are the steps that apply the patches located?

Be Well :)
Alan
