DP83867CR: Assistance with WOL Function Configuration on DP83867CR

Subject: Assistance with WOL Function Configuration on DP83867CR

Dear TI Team,

We are currently utilizing the Wake-on-LAN (WOL) functionality of the DP83867CR and aim to configure GPIO0 to output the WOL signal. The following configurations have been applied:

  • WOL_OUT_MODE (0x107): Set to pulse mode.
  • GPIO_MUX_CTRL (0x03): Configured GPIO0 for WOL output.
  • MICR (0x08): Enabled interrupt.

We are using the etherwake tool to send the Magic Packet, and the corresponding packet is successfully captured on the network. However, GPIO0 does not output the expected pulse signal.

Are there any additional configurations or steps required to enable this functionality?

Thank you for your support!

Best regards
