Ethernet packets are missing

Taras Kolesko

Hello again.

When i'm connecting the evaluation board TMDSEVM6670L through ethernet, should i see ethernet packets with board's MAC-adress?
For a 4 months ago i was able to see and track them through the WireShark, but now board remains "silent", until i'm starting to work with it, using initialization and everything.

What could be a source of the problem? Is this a hardware issue, or it's normal state?

I'm using the Ethernet boot jumper configuration

Hi Taras,
Setup your board to "DSP no-boot" mode and load the ethernet example (NDK examples) into your board and check the PHY working properly.

Hello Titus.

I'm not trying any project for now. I was detecting the packets after powering the evaluation board, but now i can track them only when i'm starting to load an ethernet project.

You can ensure that PHY section is working properly by running any ethernet example on your board.

I think, the source of the problem is in the bootstrap protocol. Several months ago i was detecting the bootstrap packets with MAC adress and evaluation board was sending back broadcast request. The future target is sending the programm to the CPU and executing it on board. But i can't solve that problem, until i'll understand, how to send packets without initialization through project and .gel Globad_Default_Setup

I would like you to suggest to use the following README.txt.
