I actually did not eplace it all. I just compiled and programmed u-boot
to flash in diferent
address than 0xfff00000 I used 0xff800000 but it is not a good choice
leaved big hole between dbug and uboot.May be the 0xfff40000 will be
more sensible choice.
Then i just loaded s-record image to RAM and copied it to flash in right
To load it in diferent address that it is intended you should use -o option
because dbug can't load directly to flash.
Now, when i am more familiar with u-boot and if i wish replace dbug
i recommend to first compile u-boot to ram address and then use ram-running
u-boot to erase dbug and program u-boot on the place. Of cource this kind of
procedures allways have risk to make dead board and then you will need
a WERY EXPENSIVE bdm tools reprogram it. So, loading u-boot
to alternate address is safest way.
Only inconvicienc of ths is that u-buut must be started grom dbug and so
extra step is needed.
