With what configuration and Buildroot version is this? Presumably with a big
initramfs? I just did a test build with 2017.05-rc3 here and
raspberrypi3_64_defconfig, and I end up with ~15 MB used in the fat partition:

sudo mount -o loop,ro images/boot.vfat /tmp/mp

df -h /tmp/mp
Filesystem      Size  Used Avail Use% Mounted on
/dev/loop0       32M   15M   18M  47% /tmp/mp

ls -lahS /tmp/mp
total 15M

-rwxr-xr-x  1 root root   65 May 30  2017 cmdline.txt

If you change the configuration significantly then it isn't surprising that you
may need to tweak other things, so this IMHO isn't a bug.

Ditto.

Agreed.

I'm closing this report. If you still have the issue with a stock
Buildroot rpi3_64 defconfig, please re-open.

Thanks! :-)

--- Comment #3 from Alexander Klauer <Alexander.Klauer@itwm.fraunhofer.de> ---
Just for the record, this was on version
a6a4a8b2ef1fa747fdc79bc7bae0518417910f5d. And yes, I added the ramdisk option
in the config, plus some other things.

I agree that more than 32M bootfs might not be necessary for most people. The
error simply came somewhat unexpected for me, since I "just changed the config"
;-)

Would it make sense to be able to configure the bootfs size via make nconfig
just as the rootfs size? Or at least print some error message pointing to the
appropriate genimage.cfg so that users don't have to dig for the size option?
If so, I could open an enhancement bug.

No, it does not make sense.

Remember that our defconfigs are just basic samples to have a board
boot up to a shell. If your use-case diverges from the sample, it is
your responsibility to adapt it.
