Part Number: LP-AM243

Hello TI support team,

I am working on example: "enet_lwip_cpsw_am243x-lp_r5fss0-0_freertos_ti-arm-clang"

Can i send or receive data on "enet_lwip_cpsw_am243x-lp_r5fss0-0_freertos_ti-arm-clang" example??

Because i search on TI support forum, i see it seem support ping, iperf with TCP/UDP.

The examples do below

Initializes the ethernet driver for the underlying HW
Initializes the LwIP stack for TCP/UDP IP
Allows user to run and test basic networking features like DHCP, ping, iperf with TCP/UDP.

Hi,

Yes, you can send data to/from AM243x LP. Current SDK apps doesn't provide standalone example showcasing the TCP or UDP application but as the existing app is based on LwIP, you can integrate your any socket based example easily.

Also you can search for readymade examples in LwIP forums.

Regards,

Prasad
