I found another endian issue. In ext4fs_get_new_inode_no() it is setting bgd- >bg_itable_unused without performing the proper endian conversion. Additionally, if it's a 64-bit filesystem, it does not set bg_itable_unused_high. -Aaron _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
