Two MAX10 FPGAs, one sends packets and the other doesn't.

[mac23]

Hello,

I have two MAX10 FPGAs1050DAF484C6GES, I run the same program and execute the same Tcl script to run the ethernet program found here Intel® MAX® 10 FPGA – Single-Port Triple Speed Ethernet and Onboard PHY Chip Design Example. One MAX10 does output the packets out to Wireshark and the other does not, giving an output that I don't understand as shown below. What could be the problem? 

Thank you for the help!

Running stats_chk the output is this for the MAX10 that does work:

I will answer in passing.

I think you know, but if you just look at the content and explain it,

The FPGA sends packets, but the other side does not transmit or is not connected.

first

0x7c aOctetsReceivedOK 0

In this case, the problems are widespread.

RX link defective (physical)

Interprotocol Differences

Destination address issues (MAC Address, etc.?)

Please try connecting to a board (equipment) that is connected normally.

It seems like we can find out if the problem is with that port.

I hope it helps you with your work.
First, you need to check whether the physical channel problem is normal.

[mac23]

I don't think it is physical or the MAC address. I ran the default program on one FPGA without adding its MAC address and it worked. I ran the same program on a 3rd FPGA and that same problem persists.

Hi mac23,

I would suggest you check the board by below steps:

1. All register setting are same
2. Check signal integrity (cable, condition of plugging, port connection and so on)
3. Do internal and external loopback testing

Best regards,

[mac23]

Hi Zying,

Could you give instructions on how to do internal and external loopback testing?

[ZiYing_Intel]

Hi mac23,

For the loopback testing, you may follow link below, Section Testing Design Example, pg20, https://www.intel.com/content/dam/support/us/en/programmable/support-resources/fpga-wiki/asset03/max10-tse-on-board-phy-design-example-user-guide.pdf

Hi mac23,

Is there any update from your side?

Hi mac23,

Since no hear any feedback from you, I now transition this thread to community support. If you have a new question, feel free to open a new thread to get the support from Intel experts. Otherwise, the community users will continue to help you on this thread.

Best regards,
