I just compiled and programmed u-boot to flash in diferent address than 0xfff00000 I used 0xff800000 but it is not a good choice because it 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 address. 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 one extra step is needed. Kate -- +==================================================================+ !
