EMAC boot, BOOTP, specify destination MAC address

Nicholas Sicalides

Hi,

I am booting multiple 6474s with an EMAC boot across multiple boards on the same network and I would like to specify the destination MAC address of the BOOTP. Currently the BOOTP packet is broadcast and I would like to specify an exact MAC address for the BOOTP. I can specify the source MAC address but the desination address doesn't take. I modify the EMAC boot parameter structure Host MAC and it doesn't work.

Is changing the destination MAC address of the BOOTP packet supported in the 6474 bootloader?

Thanks

Hi Nick,

Are you trying this through I2C secondary boot or direct Ethernet boot?

Thanks,

Arun.

Hi Nick,

Unfortunately i found out a bug in the ROM code that hard codes the broadcast address as the destination insted of using the boot parameter value for host MAC. so you cannot direct the bootp to an unique host.

Thanks.
