Hi,
I have a 7025 which i had to replace the PSU recently as it wouldn't switch on. With the new PSU is switches on ok but fails during the boot process, If I put it in flash mode it fails to get an IP address due to it broadcasting to 253.255.255.255 (the destination mac also contains a 253/FD), I realise this is wrong but do not understand why this is. This leads me to beleive either the bootloader is corrupt or I have some hardware problem.
Also if I connect over serial with dreamup to flash a new image it gets as far as "box is flashing from its memory..." and goes no further.
I am hoping this can be fixed by JTAGing the bootloader.
Has anybody encountered anything like this? I would be very grateful for any help.
