Hi Gerard,
indeed your Kernel it's quite outdated.
you can try to add a recipe like that in your image :
SUMMARY = "basic initramfs image init script"
LICENSE = "MIT"
LIC_FILES_CHKSUM =
"file://${COREBASE}/meta/COPYING.MIT;md5=3da9cfbcb788c80a0384361b4de20420"
SRC_URI = "file://init-boot.sh"
S = "${WORKDIR}"
do_install() {
install -d ${D}${base_sbindir}
install -m 0755 ${WORKDIR}/init-boot.sh ${D}${base_sbindir}/init
}
do_install_append() {
install -d ${D}/dev
mknod -m 622 ${D}/dev/console c 5 1
mknod -m 666 ${D}/dev/null c 1 3
}
inherit allarch
FILES_${PN} += "/dev /sbin/init "

Hello Ayoub,
The kernel is quite old 2.6.20 and this variable is not available in
the config.
On the internet I saw this is only introduced with kernel version 2.6.32.
Cheers,
Gerard

Hi Gerard,
did you try to set CONFIG_DEVTMPFS=y in your Kernel config ?
Cheers

Hello Andrea,
I have tried to add the line to my machine config:
IMAGE_DEVICE_TABLES = "files/device_table-minimal.txt"
But this didn't help, then I looked a bit further and also tried
to set the following:
USE_DEVFS="0"
VIRTUAL_RUNTIME_dev_manager = "mdev"
Unfortunately this doesn't seem to change anything.
Cheers,
Gerard

Hello Gerard,
if your old kernel lacks devtmpfs you need a "device table".
You need to set at least
IMAGE_DEVICE_TABLES = "files/device_table-minimal.txt"
This is a default set in image.bbclass before and after
daisy...dunno
what's happened with this release.
Cheers
Andrea
