AM2431: Operation when sending a ping

Hayato Waki

Part Number: AM2431
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

Dear person in charge.

We are developing a product using the AM2431, and the SDK version we are using is 8.03.00.
We have incorporated the Enet LwIP CPSW example into our product as a reference.
To check the quality of the network, we sent a ping, but we were unable to send data larger than 1500 bytes.
Could you please explain the cause of this issue and how we can resolve it?

Best Regards,

Hayato Waki.

Hi Ashwani,

Thank you for your reply.

We are using a custom board with the AM2431 and have embedded our product application using SDK version 8.03. It is difficult to verify the operation with the latest SDK. Has this issue been resolved in the latest SDK?

Best Regards,
Hayato Waki.

This limitation is coming from sysconfig Rx MTU size.

Hi Ashwani,

I understand that the maximum size of transmitted and received packets is specified by the 'Rx MTU size' setting in sysconfig.
If I want to increase the send/receive packet size, should I change this setting value?
Please let me know if there are any conditions or requirements for setting the configuration value.

Best Regards,
Hayato Waki.

Hi Hayato Waki,

You can try below changes:

One is syscfg GUI and another is lwipopts (MTU).
