iMx35 PDK booting from RedBoot

[jvidal]

Hi:

I trying to boot a linux compile with ltib, but when execute kernel, linux promt from iMx35 dont show...

I try next command to load kernel and root and then execute linux.

fis init

load -r -b 0x100000 zImage -h 172.16.21.4

fis create -f 0x100000 kernel

load -r -b 0x100000 rootfs.jffs2 -h 172.16.21.4

fis create -f 0x600000 root

fis load kernel

exec -c "noinitrd console=ttymxc0,115200 root=/dev/mtdblock8 nfsroot=172.16.21.4:/tftpboot/rootfs init=/linuxrc ip=172.16.21.25:172.16.21.4"

where

172.16.21.4=Host ip

172.16.21.25=Target ip

Error message say:

VFS: Cannot open root device "mtdblock8"

Please append a correct "root=" boot option; here are the available partitions

1f00 512 mtdblock0 (driver?)

...

1f08 98304 mtdblock0 (driver?)

Kernel panic - not syncing: VFS: Unable to mount root fs

Any idea what happend.

Thanks for all.

If you are trying to load root file system from NFS, then your kernel command line for root device should be 'root=/dev/nfs'.

Hi:

First, thanks for your answers wth.

How i try to ejecute from NAND flash (we load kernel and rootfs), exec commad have to do:

exec -c "noinitrd console=ttymxc0,115200 root=/dev/mtdblock8 rw rootfstype=jffs2 ip=172.16.21.15:172.16.21.4"

That is all.

Hello, perhaps you forgot to program the NOR. You must fill all the previous block or try with mtdblock0 to 7.
