TMDSICE3359: Disabling one port with PRU-ICSS-EthernetIP Adapter

Hi

unfortunately, the previous thread is already closed, but I wanted to find out if there is any news on this subject:

It looks better now, but there is still one small issue:

  • I deactivate port 1
  • no telegrams can be sent from port 1 to port 2 --> expected
  • but the telegrams from port 2 to port 1 can be seen on port 1 --> not expected

Is there anything I can do to change this behaviour?

Thank you in advance

Stefan

    Hi Dhaval,

    unfortunately I can't communicate with this updated PRU-firmware (v5.2.10) at all. I didn't take a deeper look but it seems the differences to my last version (v5.2.7) are too big and something stopped working

    Maybe there are some incompatibilies with my used software packages:

    • PRU-ICSS-EthernetIP_Adapter_01.00.03.04
    • pdk_am335x_1_0_12

    I also use this patch from on of your colleagues:

    Hi
    Is it possible for you to check with "pdk_am335x_1_0_17" from SDK v6.3?
