MPC5748G ENET

sondre89 — Thu, 25 Feb 2016 10:11:04 GMT

Hello! Is there any examples or documents where I can find information on how to configure and use ENET on MPC5748G?

Hi,

we have ENET driver for MPC5775K, but it should be the same module as on the MPC5748G. Maybe it will be necessary to update some register names because of different header files.

Regards,

Martin

Hello! Thank you for the examle code. I will try to make it work =)

Still no luck getting the ENET to work. Do i need to do something with the switch that 5748 uses?

Hi,

could you please more clarify your problem? Are you able to build/compile the project?

Regards,

Martin

My task is to send an ethernet packet from my eval board to my computer. The project can build/compile without errors. Im using the example code you gave me with some changes to the GPIO init function. As now I am using Wireshark to capture packets sendt on the network. If I understand correctly the buffer is sent when TDAR is 1 and I should be able to see the packet on the network, right ? As long as my GPIO is initialized correctly. However, after TDAR is set, there is nothing to caputre from 5748G. I think the problem is my setup of the gpio, or the clock maby. Is there anyway to debug the transmission of the buffer?

Hi,

at first, try to measure signal on Tx pin, if you are able to transmit something. You are correct about TDAR, but wireshark is able to display only PDU, which has correct format. So wireshark is the last possibility to debug.

Martin

That is a good point. Gotta freshen up some skills with the scope then. Thanks!

I am also working on the Ethernet for MPC5748G. I am also having same trouble. sondre89 did you successfully run the ENET program. If yes please can you share the code.

Thanks.

Hello! Im currently working with something else right now, so i have not been able to complete my ethernet code. However, I have confirmed that the example code, with some changes to the gpio's to fit 5748G, is able to transmit data out of the processor to the ethernet controller.

Thank you sondre89 for the reply. I was able to run the Ethernet program after changing GPIO.

Thank you.

Hello, Kushal Shah! I am also working on the Ethernet for MPC5748G, but i don't know what i need to change in the example code to run the Ethernet program correctly. if it's possible, please can you share your project code.

Regards,

Alex.

Hi alextimpau, here is the code.

It is targeted to NXP X-MPC574xG-Mother board and Daughter card board. And this project is made using S32 Design Studio for Power.

It will toggle LED DS2 when it receives the data.

You can use Packet Sender app for this.

Finally it sends packets using UDP protocol.

Hi Kushal Shah!

I have a problem when trying to upload the source code: in the final stage of debugging this error occurred

Could you please tell me what changes should I do to run this application successfully?

Best regards,

Alex.

Hi Alex,

this is the problem of S32DS. Look at these following threads. We have already solved this problem, so there are some points which you can try.

I have an error : Launching L1_Z4.elf has encoutered a problem.Error starting process.

Hi kushalshah13,

Thank you for your example project.

I am also working on the Ethernet for MPC5748G. I have the X-MPC574xG-Mother board and Daughter card board.

Can you tell me how to you test the project whether it works right?

Did you recrive packet by Wireshark?

And can you tell me which Packet Sender app can be helpful?

Thank you very much!

Hi huqiang,

You can use wire-shark to observe the received packets.

The name of other app is itself is "Packet-sender"( https://packetsender.com/)

The project is configured in polling mode for transferring packets and in the interrupt mode for receiving packets. Watch for transferred packet in above two apps directly. And for received packets interrupt is generated which toggles the DS2 LED on mother board.

Thanks,

Kushal

Hi kushalshah,

Thank you for your suggestion.

I will try it later.

Hi,

I have ported LWIP into MPC5748G project which used simple ethernet drivers including initialization, send package and receive package. Maybe you can have a reference.
