Boot EVM3517 from Ethernet

Other Parts Discussed in Thread: AM3517

I set the switches on my EVM3517 to EMAC boot.  I assume that it uses the ethernet port on the main board, not the expansion board.

Using a network sniffer and looking for broadcast packets, I don't see any.  

Why would that be?

Thanks,

Matt Gessner

    Hello Matt,

    On the current version of the AM3517 EVM board, the PHY takes sometime to be initialized and by that time the CPU sends the boot packet and hence the boot packet doesn't enter the network. This issue would be solved in the next release. However as of today, you can connect the board to Code Composer Studio and reset the CPU. The cursor in the Disassembly window should point to 14000. If it doesn't, right click in the disassembly window, set start address as 0x14000 -> right click on 14000 and select 'set PC to cursor'. If you run now, you would see the boot packet on the network as the PHY gets enough time to be initialized.

    Regards,

    Hi, and thanks for the information.

    So how do I get it fixed on my board that I spent $1000 on?
