commit: https://git.buildroot.net/buildroot/commit/?id=bf4a6490e4ee70f0a46e588602995ba34e6c872a
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
This commit adds a number of test cases for various filesystem formats:
ext2/3/4, iso9660, jffs2, squashfs, ubi/ubifs and yaffs2. All of them
except yaffs2 are runtime tested. The iso9660 set of test cases is
particularly rich, testing the proper operation of the iso9660 support
with all of grub, grub2 and isolinux.

Why the default value provided by Buildroot (Kconfig) are not used here ?

Since Qemu 4.0, this test doesn't work anymore due to a new check between the
backend and device size:
https://git.qemu.org/?p=qemu.git;a=commit;h=06f1521795207359a395996c253c306f4ab7586e
See: https://gitlab.com/kubu93/buildroot/-/jobs/1543100932
The pflash device provided by Qemu for ARM vexpress-a9 target is 64M [1] but the
ARM vexpress devicetree describe a 128M flash device [2]
The size of rootfs.ubi image is reduced to 64M to allow booting Qemu.

But for some reason, the filesystem can't be mounted...
List of all partitions:
1f00 131072 mtdblock0
(driver?)
1f01 32768 mtdblock1
(driver?)
No filesystem could mount root, tried:
ubifs
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)

https://git.qemu.org/?p=qemu.git;a=blob;f=hw/arm/vexpress.c;h=58481c07629aedb09864dcc72757ff7947e733bb;hb=HEAD#l50
[2]
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/arch/arm/boot/dts/vexpress-v2m.dtsi?h=v5.14#n33
The issue was not detected until now since we are sill using an old qemu (2.8)
for testing in gitlab (using the Buildroot Docker image used by gitlab-ci.yml).
Any idea ?
Best regards,
Romain
