Hello.

Please see attached "PinMuxDesignState_AM335x.dat". Could someone please help me to understand exactly why I get the IO set violation here?

Pinmux utility version = 2.4.1.0.

Tnx / Peter

    Hi Peter,
     
    You have a mix of GMII1, RMII1 and RGMII1 signals on the GEMAC CPSW peripheral. This is the reason. The pins for each of these (GMII1, RMII1 and RGMII1) are given in Tables 2-47, 2-49 and 2-51 od the AM335X Datasheet. Please note that there is a new version (Rev. E) of the datasheet available for download.
