booting process

booting process

[Luís Cargnini]

Hi i compiled my u-Boot based on git tree, put omn the OSK 5912 board,
compiled my Kernel based on git tree, loaded to the board too.
Now some thisng remain i need to boot it, whe i did "tftp 00100000 uImage" i
download and put uImage there then bootm works, but if after i try to upload
my jffs image nothing works.
How to fix this ?
How to boot automatically ?
my mkfs.jffs2 command: mkfs.jffs2 -U -d filesys/ -o system.jffs2.img
my bootargs: bootargs=mem=32M console=ttyS0,115200n8 noinitrd rw
root=/dev/mtdblock4 rootfstype=jffs2




the error after reloaded the kernel and did bootm
Skipping reset check for DSP domain clock "dspper_ck"
Root-NFS: No NFS server available, giving up.
VFS: Unable to mount root fs via NFS, trying floppy.
No filesystem could mount root, tried:  jffs2
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(2,0)



is write protected the flash ?

To repeat what I suggested:
Try this:
ftp://ftp.infradead.org/pub/mtd-utils/mtd-utils-1.0.0.tar.gz
from http://www.linux-mtd.infradead.org/

u need to cross compile it for arm platform with the kernel path is
properly given.. most probably the mkfs.jffs2 is the wrong version... I
suspect ur using the latest kernel from git tree...

Were you able to mount /dev/mtdblock4 while using nfs as root file system?

thanks all for the ASAP answers, now seesm working no error  reported
any more using new mtd-tools, but stopped in this
IXME: Clock "tc2_ck" seems unused
Disabling unused clock "tc1_ck"...  done
Skipping reset check for DSP domain clock "dsptim_ck"
Skipping reset check for DSP domain clock "dspxor_ck"
Skipping reset check for DSP domain clock "dspper_ck"
VFS: Mounted root (jffs2 filesystem).
Freeing init memory: 108K

and do  not boot nothing else, i putted the busybox inside the image.
but i think this is a new subject.

Actually the new EBH/Cleanmarker implementation might take a little time to mount up based on ur flash size (some concepts of a garbage collector that I don't want to go into).. I got tricked on this some time back too :). I suggest to wait atleast 1 hr (more than double the actual time), and see if u have a bootup.. If you do have a boot, then from the next time, either make ur jffs2 image the same size as the flash size OR boot from NFS, do a mount and a umount of the flash partition, etc..
