Bug ID: 8806
Summary: Buildroot 2016.2 for Raspberry Pi requires that ext4
rootfs is selected. Otherwise the error is reported
Product: buildroot
Version: unspecified
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: wzab01 at gmail.com
CC: buildroot at uclibc.org
Target Milestone: ---
I often use Raspberry Pi in a configuration, where only Initramfs is used.
It makes my system resistant to random power cuts.
Unfortunately with Buildroot 2016.2 if I do not create the Ext4 image the
board/raspberrypi/post-image.sh script crashes and generates an error.
Probably this error can be ignored, as the essential files in the output/images
are already created, but the compilation finished with ERROR doesn't look good.
Steps to duplicate the problem:
$ wget https://buildroot.org/downloads/buildroot-2016.02.tar.bz2
$ tar -xjf buildroot-2016.02.tar.bz2
$ cd buildroot-2016.02
$ make raspberrypi_defconfig
$ make menuconfig
In section "Filesystem images" deselect "ext2/3/4 root filesystem"
Select "initial RAM filesystem linked into linux kernel"
Select (optionally) Compression method (gzip)
Save configuration and exit
$make
After some time, you'll get:
>>> Executing post-image script board/raspberrypi/post-image.sh
Version: Linux version 4.1.15 (wzab at wzab) (gcc version 4.9.3 (Buildroot
2016.02) ) #3 PREEMPT Wed Mar 16 20:43:58 CET 2016
DT: y
DDT: n
283x: n
file(rootfs.ext4): stat(/tmp/mmm/buildroot-2016.02/output/images/rootfs.ext4)
failed: No such file or directory
hdimage(sdcard.img): could not setup rootfs.ext4
Makefile:667: recipe for target 'target-post-image' failed
make: *** [target-post-image] Error 1
That problem affects also those, who want to create ext2 rootfs or ext3 rootfs:
Even if you select "[*] ext2/3/4 root filesystem", the error will occur if you
select version ext2 or ext3.
Best regards,
Wojtek
