RTOS/TDA3XEVM: Disabling Ethernet Rx for debugging

Sebastian Hauschild

Part Number: TDA3XEVM

Tool/software: TI-RTOS

Hi all,

I have a network streaming application with our custom TDA3 board and a curious behavior. I want to check whether
some Ethernet messages >to< our board are causing this failure. Is it possible to disable the Ethernet Rx path?
And when it is possible, where in the code?

Thank you in Advance!

Hello Sebastian,

Do you want to disable RX path run time or statically?

You can disable RX through CPDMA_RX_CONTROL register (0x4848 4814) by writing 0. Also you can disable RX through NSP where you can comment RX start channel call.

Regards,

Prasad

Hello Prasad,

I thought to disable it statically. But on runtime may be interesting, too!
Thank you, I will try it!

Sebastian
