I believe that is incorrect. <vol name> is literally the name that can be used in the form "ubiX:<vol name>". It doesn't make sense to use the above forms when creating the volume. The ubi index is already set by calling ubi part <mtd partition>. The volume index is simply the next volume in that ubi. > and the prefix "ubi:" will be appended in the environment which is expected > by kernel for mounting. Right? I assume you meant prepended. Please expand on what you are saying here. What environment variable? Prepended by what / who? Yes, the kernel command line expects a full name in one of the 4 forms above. -Joe _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
