[U-Boot] [PATCH] AX88180: improve phy searching
by Mike Frysinger 21 Jun '10

21 Jun '10

Rather than hardcode specific phy addresses, search the possible phy address space to find the first available phy. Also respect the normal CONFIG_PHY_ADDR option for board porters to pick a specific address.

[U-Boot] [PATCH] ip/defrag: fix processing of last short fragment

TFTP'ing a file of size 1747851 bytes with CONFIG_IP_DEFRAG and CONFIG_TFTP_BLOCKSIZE set to 4096 fails with a timeout, because the last fragment is not taken into account.

Hello all, I ve googled a lot and read many mailing list entries, but got stuck now with the following problem: => ubifsmount rootfs UBIFS error (pid 0): ubifs_read_node: bad node type (0 but expected 6) UBIFS error (pid 0): ubifs_read_node: bad node at LEB 0:0 Error reading superblock on volume 'ubi:rootfs'! 1) I ve erased my nand-partition with 'nand erase' 2) I ve created a UBI partition with 'ubi part' 3) I ve uploaded my UBI image with 'tftp' 4) I ve created an volume with 'ubi create' 5) I ve written the image to the volume with 'ubi write' 6) I wanted to mount the volume --> and failed INFO: I was able to mount a UBI image, which I ve created on the device, when booting from NFS. So I guess that the UBI image is OK. Was did I wrong? Thanks a lot, Charly Here is the complete history: I ve created an UBI image from an UBIFS file with the following cmd: ubinize -orootfs.ubi.img -m2048 -O512 -p128KiB ubinize.cfg and this ubinize.cfg [ubifs] mode=ubi image=rootfs.ubifs vol_id=0 vol_size=512MiB vol_type=dynamic vol_name=rootfs vol_flags=autoresize => setenv mtdids nor0=fc000000.flash,nand0=mpc5121.nand => setenv mtdparts 'mtdparts=fc000000.flash:256k(protected),60m(filesystem),2560k(kernel),256k(device-tree),1024k(u-boot);mpc5121.nand:-(ubi-data)' => mtdparts device nor0<fc000000.flash>, # parts = 5 #: name size offset mask_flags 0: protected 0x00040000 0x00000000 0 1: filesystem 0x03c00000 0x00040000 0 2: kernel 0x00280000 0x03c40000 0 3: device-tree 0x00040000 0x03ec0000 0 4: u-boot 0x00100000 0x03f00000 0 device nand0<mpc5121.nand>, # parts = 1 #: name size offset mask_flags 0: ubi-data 0x20000000 0x00000000 0 active partition: nor0,0 - (protected) 0x00040000 @ 0x00000000 defaults: mtdids : nor0=fc000000.flash,nand0=mpc5121.nand mtdparts: mtdparts=fc000000.flash:43776k(user),16m(rootfs),4m(kernel),256k(dtb),1m(u-boot);mpc5121.nand:-(data) => nand erase ${start of ubi-data} ${size of ubi-data} Skipping bad block at 0x1ffc0000 Skipping bad block at 0x1ffe0000 OK => ubi part ubi-data Creating 1 MTD partitions on "nand0": 0x000000000000-0x000020000000 : "mtd=0" UBI: attaching mtd3 to ubi0 UBI: physical eraseblock size: 131072 bytes (128 KiB) UBI: logical eraseblock size: 129024 bytes UBI: smallest flash I/O unit: 2048 UBI: sub-page size: 512 UBI: VID header offset: 512 (aligned 512) UBI: data offset: 2048 UBI: empty MTD device detected UBI: create volume table (copy #1) UBI: create volume table (copy #2) UBI: attached mtd3 to ubi0 UBI: MTD device name: "mtd=0" UBI: MTD device size: 512 MiB UBI: number of good PEBs: 4064 UBI: number of bad PEBs: 32 UBI: max. allowed volumes: 128 UBI: wear-leveling threshold: 4096 UBI: number of internal volumes: 1 UBI: number of user volumes: 0 UBI: available PEBs: 4020 UBI: total number of reserved PEBs: 44 UBI: number of PEBs reserved for bad PEB handling: 40 UBI: max/mean erase counter: 0/0 => ubifsmount ubi-data UBIFS error (pid 0): ubifs_get_sb: cannot open "ubi:ubi-data", error -19 Error reading superblock on volume 'ubi:ubi-data'! => ubifsmount rootfs UBIFS error (pid 0): mount_ubifs: can't format empty UBI volume: read-only mount Error reading superblock on volume 'ubi:rootfs'! => tftp rootfs.ubi.img Using FEC ETHERNET device TFTP from server 10.1.1.83; our IP address is 10.1.1.84 Filename 'rootfs.ubi.img'.
