  • Forum Post: How constitute ethernet more than two?

    challenger
    Hi, I need ethernet more than 2 ports(as router function) though our target device is AM3505. AM3505 only have one EMAC, so what is the most suitable way to constitute more than 2 ethernet port which function as a router ? Is this constitution similar with the AM3517EVM? (one ethernet on baseboard...

  • Forum Post: Re: AM335X ,Switching Between Ethernet and EtherCAT on the same port

    Frank Walzer
    Dear Faraz, theoretically yes, but in reality it is a bit more complex. There is no 'EtherCAT port' connected to PRUSS first of all. PRUSS has two dedicated MII ports which can interface to Ethernet Phys. However the standard or protocol that then runs via the two ports is defined by software...

  • Forum Post: AM335 Ethernet Interupt pacing implementation??

    Charles H
    Is interrupt pacing implemented for Ethernet ports of AM3352? I saw this on TI web site. If lots of interrupts comes for every small packet from Ethernet port, it will slow down CPU. I think what they do is they hold back interrupts and generate one interrupt for multiple packets. See TI site below...

    Hi, I notice from the data sheet and technical reference Manual that the RGMII interface is not available in OPP50 mode. Is this a performance issue, such that I cannot use 1G Ethernet in OPP50 mode, but can continue to use 100M Ethernet if I force my 1G Ethernet PHY to negotiate to 100M which is...
