TDA4VM: cpsw conflicts with the rtos memory map

cesar.xu
Intellectual 360 points
Part Number: TDA4VM

Hi TI,

1. CPSW can communicate normally on Linux,

the uEnv.txt config:  name_overlays=k3-j721e-gesi-exp-board.dtbo

The system automatically assigns ip addresses after running

2.add rtos-mmap dts:   name_overlays=k3-j721e-gesi-exp-board.dtbo k3-j721e-edgeai-apps.dtbo

The network does not assign ip automatically after restart system 

3.After trying the following operations, the network is normal, why does this address conflict with cpsw
