Ethernet Driver for AURIX TC299 TRB Dev Board

[eric_cal]

I'm looking to set up a TCP demo utilizing LWIP on an AURIX TC299 TRB (Step BB) development board. I noticed that Infineon's GitHub repository doesn't include code examples for TC299 TRB boards but have tried to use examples for TC297's to some success. Specifically, I've been able to get a loopback example to run to conclusion but nothing else.

Two questions:

1) is there an example of an Ethernet driver for TC299 TRB dev boards? If not, then

2) which project is compatible with my dev board's MAC/PHY setup? e.g. do I use RMII or GMII in the PHY setup?

Thanks in advance!

• For eth demo, please refer to the demo project of TC2xx on myICP.
• Please use BIFACE to open the project, which is on myICP also.
• PEF7071 is used for PHY.

• Please refer to AURIX TC297x TFT Application Kit Firmware\0_Src\0_AppSw\Config\Common\Configuration.h for RMII pins definition.

Thanks for the response.
How long does it usually take to get accepted into myICP after sending the request to the parties listed on myICP's page?

Hi eric, It's suggest to resend the apply email more times if no response.

With all features, except for the LWIP itself, disabled I've managed to get the project compiled as prescribed above and loaded onto the dev board. Unfortunately, the LWIP fails to initialize.

In AURIX TC297x TFT Application Kit Firmware, there is lwip support, you can step into this function for initialize iwip

Ifx_Lwip_init(ethAddr);

The project is in myICP.
