 |
|
Dear all,
I am using a iMX 31 phytec development board with linux as target and
a x86 machine with 10.2 suse linux as host platform.
The target is booting up successfully with the original image . I just
tried to compile the target linux source package and downlaoded into
RAM and then copied into flash I am getting the message
No filesystem could mount root,tried:jffs2
kernel panic-not syncing:VFS:unable to mount root fs on unknown-
block(2,0)
here is some settings in config file
#
# Boot options
#
CONFIG_ZBOOT_ROM_TEXT=0x0
CONFIG_ZBOOT_ROM_BSS=0x0
CONFIG_CMDLINE="noinitrd console=ttymxc0 root=/dev/mtdblock2 rw
ip=off"
# CONFIG_XIP_KERNEL is not set
# Memory Technology Devices (MTD)
#
CONFIG_MTD=y
# CONFIG_MTD_DEBUG is not set
# CONFIG_MTD_CONCAT is not set
CONFIG_MTD_PARTITIONS=y
# CONFIG_MTD_REDBOOT_PARTS is not set
CONFIG_MTD_CMDLINE_PARTS=y
# CONFIG_MTD_AFS_PARTS is not set
# Miscellaneous filesystems
CONFIG_JFFS2_FS=y
CONFIG_JFFS2_FS_DEBUG=0
CONFIG_JFFS2_FS_WRITEBUFFER=y
# CONFIG_JFFS2_SUMMARY is not set
# CONFIG_JFFS2_FS_XATTR is not set
# CONFIG_JFFS2_COMPRESSION_OPTIONS is not set
CONFIG_JFFS2_ZLIB=y
CONFIG_JFFS2_RTIME=y
# CONFIG_JFFS2_RUBIN is not set
Do I need to set any variable using setenv on uboot prompt
Thanks in advance |

First of all what did you mount as root when using the original image
(was it NFS, Ramdisk ....) ? Try passing what ever root arguments you
pass in to the original image from Uboot. |

Hi Janaka,
The original image mounted over the mtdblock device- flash with jffs2
Here are the environment variables in the uboot command line parameter
uboot>
printenv
bootdelay=3
baudrate=115200
netmask=255.255.255.0
nfsrootfs=/
nfsroot
bootc192.168.3.11
serverip=192.168.3.10
root=/dev/
mtdblock3
bootargs_flash=setenv bootargs root=31:03
rootfstype=jffs2
mtdparts=phys_mapped_flash.0:128k(uboot)ro,128k(env),1792k(kernel),-
(jffs2 fs)ro
root=/dev/
mtdblock3
stdin=serial
stdout=serial
stderr=serial
the result of cat /proc/partition (original image)
root@phyCORE-iMX31:/proc cat partitions
major minor #blocks name
31 0 128 mtdblock0
31 1 128 mtdblock1

31 6 4096 mtdblock6
31 7 20480 mtdblock7
31 8 40944 mtdblock8
The result of cat /proc/mtd (original image)

mtd7: 01400000 00004000 "nand.rootfs"
mtd8: 027fc000 00004000 "nand.userfs"
The kernel image was copied to mtdblock2
file system image was copied to mtdblock3
