Since the ubi/ubifs test has been introduced, it's not possible to
boot the same ubi image twice [1]:
"TODO: if you boot Qemu twice on the same UBI image, it fails to
attach the image the second time, with "ubi0 error:
ubi_read_volume_table: the layout volume was not found"."
For some reason, the kernel corrupt the ubi image if the ubifs
rootfs is mounted with write access. Use a custom config file
to mount the rootfs readonly (vol_type=static). Doing so requires
to add the flash size (vol_size=64MiB).
At least it allows to boot several times the same ubi image.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
