AM3359: Ethernet RGMII mode TCLK is 20MHz instead of 25MHz

ti_user

Part Number: AM3359

Hi,

AM3359 Processor running with CORE clock of 25MHz on a custom-designed board, it is configured with Ethernet Port 2 RGMII 100Mbps.

When we probed the 'rgmii2_tclk' it is observed 20MHz frequency instead of 25MHz.

Please suggest which all configurations to be updated. Thanks!

Do you mean TI Sitara SDK v7.1 which was released in 2014? If so, the software is too old and is no longer supported on this forum. Please migrate to the latest Processor SDK Linux:

Hi Bin Liu,

Tried with the latest versions and much response of Ethernet ping in Uboot, so reverted to v7 which is working set of our previous hardware.

Any help is most welcome on either of versions. Thanks!

Hi,

Since you are using the current software please attach to this thread the information from this checklist concerning the ethernet setup on your board. Thank you.
