AM62P-Q1: Ethernet enable in U-Boot to send data

Hello SI,

Is it possible to enable all 2 Ethernet ports in U-boot and send data through Ethernet ports in AM62P?

From my understanding, you would need to ensure that the two ethernet ports are configured properly in the U-boot device tree to enable them in U-boot. Additionally from my understanding, because U-boot is a stateless environment, traffic cannot be initiated by the connected link partner, only U-boot should initiate all of its network transactions.

If possible, what protocol can be used to send data through Ethernet?

The ones I know of are ping (ICMP), DHCP, TFTP. There may be other protocols that can be used but as I'm not a U-boot expert I cannot make a conclusive comment on all possible Ethernet protocols that can be sent through U-boot.

Do you have any data how much time it takes to enable any of one Ethernet port and send 2MB data through Ethernet port in U-Boot? 

Unfortunately, I don't have data on how much time it would take to send specifically 2MB data through one Ethernet port in U-boot. In terms of U-boot, we don't do much Ethernet benchmarking as compared to Linux.

Please let us know if you have additional questions.
