Sorry, I misread/misapplied your previous suggestions. > >> IMAGE_FEATURES_append = " read-only-rootfs" > > Try EXTRA_IMAGE_FEATURES += instead of IMAGE_FEATURES_append I've changed both of these and it still fails if I enable the read-only-rootfs. If I leave that option out, I can build an .hddimg which I dd'd to my USB stick. It tried to boot, finds /vmlinuz but fails to find /initrd My local.conf settings are now: # Live CD setup IMAGE_FSTYPES += " live" #IMAGE_FEATURES += " read-only-rootfs" CORE_IMAGE_EXTRA_INSTALL += " python-core python-modules" Finally, during one of my builds, I ended up with a core-image-minimal*.iso I tried burning this to a CD an it booted up, albeit with a couple of complaints about a read-only rootfs. Sadly, I no longer get any .iso results when I 'bitbake core-image-minimal' -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------
