Network connection problem with TMDXEVM6657L

By connection lost, did you actually see that the link goes down in the status bar in windows?

Thanks,

Arun.

I am using Windows 7.   Seeing network status in Control Panel, it indicated no connection as soon as EVM network cable is connected to hub.  In the same token, network connection restores as soon as EVM network cable is disconnected.

Thanks.

Can you try and flip one of the boot strap pins to avoid run the HUA demo and see still you are having the problem.

Thanks,

Arun.

There 18 flip pins on three switches.  Which one should I flip and from what to what (0 to 1, or 1 to 0)

SW3, you can toggle any one of them. Just remember to bring them back.

Thanks,

Arun.

I turned pin 8 from ON to OFF, then press the cold reset buttom.  There is no output from COM1.   There is no change to the network problem.    I have the same network problem as before.

Is there anyone answering my questions?  In addition to this network problem.  I also has issue building examples for this TDMXEVM6657L EVM.  Please respond.  Thanks.

Hi SGQ,

I am trying to reproduce this, but my setup is not getting the DHCP address. I will let you know my findings soon.

Thanks,

Arun.

Hi Steve,

Please try switch settings as below:

          (PIN1, PIN2, PIN3, PIN4, PIN5, PIN6, PIN7, PIN8)

SW3 (off,      off,      on,       off,     on,      on,     on,      on)

SW5 (on,      on,      on,      on,     on,      on,     on,      on)

Please let me know your network problem gets resolved or not? You will get output on COM1. By this switch settings Power On Self Test will execute.

If it still network problem does not get resolved, please try the same by changing Ethernet cable.

Also please let me know issues you are facing to build the examples for TMDXEVM6657L EVM.

Thanks

Hi Rakesh,

Here is the power on test result, all pass.

POST result: PASS

Then I put SW5 bit 4 back to off, pressed cold reset bottom, the network works fine now.   Why?  What have we corrected by running POST?

In build project "property" General->Device->Variant: Generic devices, Generic C66xx Device.  I can build the example projects.

But  if I select "property" General->Device->Variant: C66xx Multicore DSP, TMS320C6657.  I got device not supported build error.  I thought this setting is more precise.

Thank you.

Steve
