.jffs2 is for burning to the device, .tar.gz is a copy of the same filesystem in case you want to set up a root-on-sd environment .. > What is considered the "image"?

The filesystem contains a full-blowing linux setup, the kernel is just that - a kernel, and u-boot is the first thing your FR runs when it starts up .. > Lastly, does each image have a corresponding kernel so flashing to a > new distribution would always require flashing the kernel as well? > If not, how can I know when flashing the kernel is also required? Kernels are released periodically in the current build hosts, but the rule is if you don't see one released with a new .jffs2/.tar.gz image, use the latest one before it .. not all releases need a kernel update, just a new filesystem tweak or two .. > Is this information on the wiki somewhere and I just missed it? > Do a search for 'dfu utility' on the wiki for more details .. ; -- Jay Vaughan _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
