I've created a squashfs file system with Yocto (it use squashfs-tools) and u-boot command sqfsls give the error:'Error while searching inode: unknown type.' After some digging in the code I found that the index is off by 1. This patch fix this issue and I can successful use the sqfsls command. After search for the squashfs format I found a link talk about a similar issue but this time in the documentation.
