TDA4VL-Q1: ICMP Protocol "Checksum"

Emad Halim

Part Number: TDA4VL-Q1

Tool/software:

We used SDK 8.6 but the calculation of the ICMP CRC by HW is not supported , is there any solution for this issue?

"Eth_setPseudoCheckSum" this API handled the UDP and TCP checksum, but there is no reference for the ICMP , so when we ping the sensor with its IP , the return value is that the checksum is not correct , please support this issue as this is a blocked issue for us as the sensor is not able to ping and pong correctly.

Hi,

ICMP checksum offload is not supported, only TCP & UDP alone supported.

No, there is no plan to add this support.

May be you can refer to existing UDP/TCP and add support for ICMP.

Best Regards.

No need of new ticket.
As it is a new future will take some time to make it available.

You can enable checksum for ICMP packets at network stack side.
