No RedBoot partition table

No RedBoot partition table

[Hsu sabrina]

Hi, Linux gurus!
I’ve got a problem with booting my kernel. The kernel on reference board 
boots successfully while on my board fails. The only difference is a flash 
memory I use in my board. I understand that I need to make some adjustments 
but unfortunately I’m not a linux specialist. I attached the boot log and 
marked differences in booting process.
Reference board:
6 RedBoot partitions found on MTD device phys_mapped_flash"
Creating 6 MTD partitions on "phys_mapped_flash":
0x00000000-0x00040000 : "RedBoot"
0x00040000-0x00100000 : "kernel"
0x00100000-0x00e80000 : "root"
0x00e80000-0x01fe0000 : "unallocated"
0x01fe0000-0x01fff000 : "FIS directory"

My board:
No RedBoot partition table detected in phys_mapped_flash
Using physmap partition definition
Creating 3 MTD partitions on "phys_mapped_flash":
0x00000000-0x00100000 : "Bootloader"
0x00100000-0x00300000 : "Kernel"
0x00300000-0x02000000 : "UserFS"

As you can see when booting kernel it can not find partitions. Did anyone 
experience the same?
Pease help me find a solution to this problem, give an advice or link to 
resources can help me.

Thanks in advance,
Sabrina

You should first verify that your board can boot by directly loading the
images into ram through tftp:
load -v -r -b 0x800000 root
load -v -r -b 0x1600000 kernel
exec

If that works you need to correctly create the partitions on the your
board's NOR flash using the fis command. See the Redboot user's guide.
