Hello,
One of our customers is designing with the AM5728 and needs some help on the following quesitons:
- For the GiGE RGMII interface they get the following results when they use a loopback cable;
- AM572x EVM, Bandwidth: 794 Mbps, Jitter: 0.008ms, Packet Loss: 0.89%
- Customer Implementation, Bandwidth: 714 Mbps, Jitter: 0.001ms, Packet Loss: 0.46%
Is this what you would expect? Is there a limiting factor or can you advise of how they can improve on the bandwidth?
- They implemented the same DDR as the AM572x EVM to de-risk the project but they're wondering whether we have a tool for setting up the DDR that would advise of register settings to aid them in specifying different DDR devices. When they have worked with other suppliers they have been provided spreadsheets to aid with this as there are a significant number of DDR registers.
Regards,
Ryan B.
