Created attachment 9251 [details] Last portion of the log Hello, I tried to build an image with a btrfs filesystem for a raspberry pi but at the end of the make command the genimage script look for a file ending by a .ext4 extension where it should be a .btrfs in my case. Setting the desired extension make the build succeed. Please note that I'm new to the embedded world so I may be missing a configuration somewhere, you can find the relevant part of the log attached. Thank you very much.
The genimage.cfg that is shipped with Buildroot is only meant for the Buildroot configuration. If you change the configuration, you're also expected to change other parts accordingly.
My bad, thank you for your time :-)
