@duggy
Thanks for the reply and conratulations on your success regarding flashing with BBS( bradband studio).
What starting address did you use when flashing ? 0x00000000 ? Or different?
Can you please also check
if you change a value of a register , will the value remains there after restart ? Or will be set to the default value before you changed the value of the register?
Thank you for help

The offset depends on what you're flashing. If its a full dump it will be from 0x00000000
Look at other people posting serial output and look at their MTD layout in the serial output to understand where you should program from. When I only programemd the CFE on my box (UNO) I programmed from 0x00000000
As for the value of the register, do you mean on the nand?. It would only be the same if the nand was RO. I can change anything and it does persist after reboot. The machine acts like it should.
Have you changed your nand?, did you use the same type of chip?, or did you use one from a different manufacturer?.
We need to have all the facts to help
You can PM me if you want to keep details private.

I checked http://www.vuplus-community.net/board/threads/nand-replacement.20604/page-2
I studied your MTD layout post #23
but MTD layout looks like
Creating 8 MTD partitions on "bcm7xxx-nand.0":
0x0000000000000000-0x0000000007200000 : "rootfs"
0x0000000007200000-0x0000000007600000 : "kernel"
0x0000000007600000-0x0000000007a00000 : "boot"
0x0000000007a00000-0x0000000007c00000 : "splash"
0x0000000007c00000-0x0000000007d00000 : "cfe"
0x0000000007d00000-0x0000000007d80000 : "mac"
0x0000000007d80000-0x0000000007e00000 : "env"
0x0000000007e00000-0x0000000007f00000 : "nvm"
you say:
When I only programemd the CFE on my box (UNO) I programmed from 0x00000000
but from your MTD layout I can see 0x0000000007c00000-0x0000000007d00000 : "cfe"
so, it means cfe starts at 0x0000000007c00000
Why do you use 0x00000000 as the start?
I also sent to you PM. Please check and reply

I think I programmed it at 00000000 (trying to remember myself now), but now i'm doubting myself. In any case its easy to test, as with BBS3 you can write to both locations. Once its in the right place the box boots and you can use from USB to flash remaining parts required.
the ONLY thing you need on the nand is the CFE because once that is programmed you then use the USB to do a full flash, this is 100% true as thats how i did it. The CFE is tiny so you can test writing it at both ofsets to find the right one very quickly. I didnt write down which one I did and I thought it might be 0x0000000000000000 but the message above implies I wrote it (correctly) to 0x0000000007c00000. I'd try that first
