The dual port is an EXPI9402PTBLK
Thanks for the help,
Good day. Here is what you can try:
1. Generate .NIC file using bootutil with the following command:
bootutil64e –devid=0x0000 –di=efi
Please obtain the device ID and fill it up in the -devid field.
2. Use LANCONF and write it to the firmware with the following command:
lanconf WRITEEEIMG FILE.nic
3. The LANCONF tool can be acquired in our Design Center, registration is required. If the LANCONF command didn't work, you may check the documentation found in the design center or you can simply post your inquiry in our embedded communities.
Hope the above information help.
We moved on to find a different overall solution. I hope to be able to get back and try this one day for potential future needs, but haven't been able to confirm it yet.
