12 Checklist for Requesting Ethernet Support

When posting an inquiry on the TI E2E™ forum (related to an Ethernet communication issue using a Linux OS on the DUT), answer the following questions or complete the requested steps in the initial post:

  1. What is the TI SDK version in use?
  2. What is the TI processor in use?
  3. Is the DUT a TI EVM or a custom board?
  4. What is the test topology?
  5. If using a custom board, attach the DTS file for the custom board; do not cut and paste the DTS contents as the DTS file can be very long creating difficulty for readers to parse
  6. Attach the console boot log of the DUT
  7. Attach the results of ethtool <interface name> and ethtool -S <interface name> for the interface with the issue
  8. Indicate that you have reviewed this application note
