Description Darren Hart 2012-06-14 21:55:00 UTC

poky-tiny builds systems without block support by default. The intended method for booting a poky-tiny core-image-minimal image is using the cpio.gz image with /dev/ram0 as the rootfs. For example:

$ qemu -kernel bzImage-qemux86.bin -initrd core-image-minimal-qemux86.cpio.gz -nographic -append "console=ttyS0 root=/dev/ram0"

runqemu doesn't have anyway to run in this mode that I could see. This impacts Hob's ability to run a poky-tiny image.

Looks like Kai has a full or partial fix for this in his work on bug #2579.

Comment 2 Scott Garman 2012-08-19 17:03:55 UTC

Fixed in oe-core and poky master as of:
