Hello Linux powerpc community,
I am trying to move from 2.6.20 kernel to the new 2.6.27.4 kernel. I am not finding my root file system partition with the new kernel. I am not sure if I need to change my dts file, or if the problem is some where in my kernel config. In either case, it is evident from the boot log that my partition table is not being used. Where it says "[ 0.917162] List of all partitions:" it just lists the entire size of my flash, and none of the partitions listed in the command line. I do not list any partitions in my dts file, though I tried and not seen any change in the behavior. I have enabled the option in the kernel to parse the partition information from the kernel command line, is there something else I need to do to set up the mtdblockX devices? Boot Command: mtdparts=mtdparts=nand0:2m(u-boot),3M(kernel),128K(dtb),30M(jffs2),32M(m ycust),90M(myfs),90M(myfs2) mtd_args=setenv bootargs root=/dev/mtdblock3 rw rootfstype=jffs2 $mtdparts console=ttyS1,115200 Boot Log: [ 0.825229] brd: module loaded [ 0.837681] loop: module loaded [ 0.841404] Driver 'sd' needs updating - please use bus_type methods [ 0.850005] NAND device: Manufacturer ID: 0x2c, Chip ID: 0xda (Micron NAND 256MiB 3,3V 8-bit) [ 0.859783] Bad block table found at page 131008, version 0x01 [ 0.867779] Bad block table found at page 130944, version 0x01 [ 0.875443] RedBoot partition parsing not available [ 0.884431] eLBC NAND device at 0xff800000, bank 0 [ 0.890643] i2c /dev entries driver [ 0.899633] Driver for 1-wire Dallas network protocol.
