NDK V2.00 TxFIFO and RxFIFO

Venkat Kumar

Hi,

I'm going to use the NDK package for my application. I have few queries regarding the same.

- Does NDK has Tx and Rx FIFO which can be used by the application to send the IP packets ?.

- Tx Q and Rx Q mentioned in the NDK document is accessible only by the EMAC driver ? Can application use this Q to send IP packet ?

- Any document describing the examples of NDK usage and how to schedule the tasks for the same would help me.

Thanks in advance for the answers.

Regards,

The NDK itself is a software creature that supports APIs to the application.
You should use socket mechanism, socket create and socket bind to connect your application to the NDK.
The layer that connects NDK to the drivers is the NIMU (network Interface Management Unit)

The MINU configures the Eth driver.

For the KeyStone family the eth driver based on the NETCP and the PA and the application cannot access it.

Again, the application sends IP packets using socket send

To see more information you can look at the examples in the release,

and of course the following documents (I assume you have them already)
