Hello yocto world
I desperately need some help
It spawns off my yocto build, so I guess (hope) there is a wise guy or
two,that can give me some pointers
I realize is not 100% yocto related but, lean towards generic Linux - so
please forgive me.
I want to be able to boot up from flash, using a rw ramdisk that
'vanish' when I reboot.
I use SYSLINUX to boot the target.
I have a recipe that can build an image, that works fine.
Now I want it convoluted in an intramfs.
my image recipe
mybase.bb:
DESCRIPTION = "A base image that boots and work"
ALL_MY_APPS= " app1 app2 app3" ## all the software i want on target"
IMAGE_INSTALL = "packagegroup-core-boot ${ROOTFS_PKGMANAGE_BOOTSTRAP} \
${CORE_IMAGE_EXTRA_INSTALL} ${ALL_MYAPPS}"
inherit core-image
It creates a nice mybase-image-genericxx86..hdd image and I copy the
contents to my flash card.
All very nice
it gets booted,with these lines in syslinux.cfg
LABEL boot
KERNEL /vmlinuz
APPEND initrd=/rootfs.img LABEL=boot root=/dev/ram0
But If I make a new
conf/initramfs.conf:
IMAGE_FSTYPES = "cpio.gz"
INITRAMFS_IMAGE = "mybase"
INITRAMFS_IMAGE_BUNDLE = "1"
and then run the command
bitbake -R conf/initramfs.conf mybase
I as expected get an bzImage-initramfs-genericx86.bin
I presume this file contains the kernel as well as my rootfs as the initrd
But what to put in syslinux.cfg ?
The logical choise seems to be:
LABEL boot
KERNEL /bzImage-initramfs-genericx86.bin
APPEND LABEL=boot root=/dev/ram0
but it doesn't boot at all. Only flicker on the console, seems to be
invalid code.
Any advice any one ?
