Hi,

We are using AM437x IDK board for development.

It looks like the PRU Ethernet Port LED indications are wrong.

Without connecting ant cable to the PRU port, The activity LED is continuously glowing(MLED of TLK105L) .

Seems like we have to configure MLED control register on TLK105L(7.3.4 Multi LED Control register (MLEDCR))

Please let us know how we can configure this.

Regards,

Jinu Jacob

Which LED is glowing? Yellow or green?

Yellow LED is continuously glowing .
We tested with sample EtherCAT code without any modifications.

Hi Jinu, I think, right LED status, in solid yellow, before connection is OK. This LED shows connection speed. Left LED (green) shows when link is up

thank you,

Paula
