MCU-PLUS-SDK-AM263X: Data transmission with EST using lwip

Hi Josh,

I suggest you to move to latest version of MCU+ SDK which is mcu_plus_sdk_am263x_08_03_00_23.
You can download the same at - MCU-PLUS-SDK-AM263X Software development kit (SDK) | TI.com
Also, do let us know if the problem is recurring on the latest version of MCU+ SDK ?

Thanks and Regards,

Aakash

Josh,

Could you please confirm if you are setting the following config params?

hostPortCfg->rxVlanRemapEn = true;
hostPortCfg->rxDscpIPv4RemapEn = true;
hostPortCfg->rxDscpIPv6RemapEn = true;

Also, note that Wireshark timestamps are not very accurate. Preferable to use specialized equipment if available.

Hi Misael,

Yes, I added the cpswcfg in LwipApp_init()

And we capture the packet using Vector VN5640.

Hi Aakash,

It needs some time to do the modification to the new SDK, I'll feedback you later.

Josh
