No UDP Packet are sent (MPC5748g DEVKIT board)

[raphael_djondo]

Hello,

I have started to use the MPC5748G_SDK_Z4_0_GCC with Processor Expert (with NXP S32 Design Studio).

I have generated the Processor Expert code after adding the ENET Component to the project.

Unfortunately, when I execute this project, no UDP packets are sent at all from the MPC5748g DEVKIT board : I am sniffing the Ethernet traffic with a different PC in promiscuous mode and I can see that no UDP packets are sent. Also, the LED on the Ethernet connector is not blinking when I running it.

Is there a particular GPIO configuration to set to allow packets to be sent ? If so, how to set it correctly through Processor expert?

Thanks

Hello,

I think you do not have configured pins in your project. Please see the enet_ping_MPC5748G example included in S32 Design Studio to check correct pin settings.

If you have any other questions, please feel free to write me back.

Regards,

Martin

Hi Martin:

I have successfully run enet_ping_MPC5748G example on DEVKIT-MPC5748G board.

However, I can not run lwip_mpc5748g project after successful build. The board is not responding to

any udp, tcp, or http packet.

Could you give me some hints for this situation?

Thanks

Hello Martin,

The pins needed to be configured (with the right direction for one of them) and setup the pins using a call to PINS_DRV_Init.

I managed to get the Ethernet examples working (UDP, TCP, ...) using the lwIP framework + FreeRTOS example.

Thanks!
