When I was messing with some custom hardware configs last week I was getting exactly the same error, that the “defconfig” does not exist in “HEAD”. This error popped up when I used the ./configure.sh inside the directories.
The PX4 documented “make board_name menuconfig” doesn’t even build for me, just crashes, I don’t get to see the NuttX config UI.
I’ve installed the PX4 dev env with the script provided in their dev sections. My other post is about not linking issues but I would like to hope it’s a separate issues.
Replying so I get updates.
