TMDS243GPEVM: MCU-PLUS-SDK-AM243X-08-02-00-12 enet_lwip_cpsw with no link

Part Number: TMDS243GPEVM

Hello experts

I can't get a link to the ethernet port (connected to CPSW port) if I download the example enet_lwip_cpsw_am243x-evm-xxxx- to my board. Nearly the same example enet_lwip_icssg_am243x-evm-xxx connected to ICSS port is working fine. The one and only difference to your deployed example is LWIP_DHCP = 0 and I have configured my own IP address.

==========================
ENET LWIP App

5. 33s : CPU load = 3.08 %
10. 33s : CPU load = 2.84 %
15. 33s : CPU load = 2.84 %

Do you have any idea what I'm doing wrong?

Thanks,

Only one annotation: the same example from your mcu_plus_skd_am64x_09_01_00_36-sdk ist working fine with the am243x evm. But I don't see any difference.

Hi Klaus,

can you please apply the below patch for the lwip example and see if that it helps.

Hi Sonu

the entries enet_cpsw1.x =x solve my problem! Now link is going up and down as expected.

Thank you!
