Good day!
I'm working with custom board with C6678 DSP. Both two DSP SGMII ports are connected at our board to AMC interface ports 0 and 1 correspondingly. I'm using the board installed at NAT NATIVE-C1 MTCA chassis with 6 AMC slots. Ports 0 and 1 of all AMC slots are connected to NAT-MCH Fabric A. NAT-MCH is connected to LAN via font-panel RJ45 connector.
I'd like to use TI ROM Bootloader (RBL) Ethernet boot at my board. I set DSP bootmode to Ethernet boot and power on the board. DSP starts sending Ethernet-ready frames without any interval, one by one, so I couldn't do anything (I cann't attach Wireshark capture file)! If I turn off AMC port 1 at NAT-MCH 1GbE switch then DSP starts sending Ethernet-ready frames as expected, with about 3 seconds interval.
My question: is this behavior of TI RBL with two DSP SGMII ports connected to the same LAN normal or is it a bug?
