That’s why ensure the ENV is install correct before even start.
There are so many unclear factors RAM not set enough CPU # is not enough causing such etc.
If the ENV is set properly there is no way build cannot pass. At least I ends up building all boards wo issue here.
This is completely expected when HDMI license are not included in some point when all the boards will generate no matter w / wo prebuild flag.
The make will automatically grep the head of the repository and i.e. build all as post suggested after line 105,165 can be remove accordingly.
I just lost interest on fixing the make script and post out here as 1st make fail you can goto the build project modify it and rebuild which the grep will inherently see it is exist and wo refresh it.
