Re: [U-Boot] Problems with ext2ls SD
Dear Karl, In message 669754ad0903281214x77796b95x76062f1c428ec...@mail.gmail.com you wrote: I am simply using fdisk under Ubuntu 8.04 and a 2GB SD card, I create a primary partition of type 0x83. When I run dumpe2fs it shows an inode size of 256 bytes. I confirm the problem. I finally found some time to run some tests, and was able to reproduce the problem. I even re-tested the old patch that Ryan Chen posted long ago (in July 2008), but as my earlier tests indicated, this patch is seriously broken and does not work at all. So we have to state that ext2 file system support in U-Boot is broken for recent ext2 versions which use bigger inode sizes.

Further debugging reveals UBoot uses a fixed length for inodes (128 bye). The inodes on my 2GB SD card are 256 bytes There was a patch that fizzled out back in January looking at this http://www.nabble.com/-U-BootPATCH--Fix-ext2-non-working-td21742132.html#a21742132 The superblock contains the inode length in the function static int ext2fs_read_inode() ... inodes_per_block = EXT2_BLOCK_SIZE (data) / __le32_to_cpu(sblock-inode_size); ... status = ext2fs_devread (((__le32_to_cpu (blkgrp.inode_table_id) + blkno) LOG2_EXT2_BLOCK_SIZE (data)), __le32_to_cpu(sblock-inode_size) * blkoff, sizeof (struct ext2_inode), /*HACK till I fix up struct size*/ (char *) inode); This seems to improve matters for me BUT I dont have any other hardware to test on and I am no ext2fs guru.
