 when we try to ping ethernet in RGMII Mode with auto negotiation  we are getting Host is not alive.

But in uboot 2018 version it is working fine in RMII (100mbps).

Please find the below attached screen shots for configuration,what we have done  for ethernet in uboot-2023V.

please help us in this regards.

Hi @Navaneeth kumar 

Latest STM32MP1-ecosystem-v5.0.0 uses U-Boot v2022.10-stm32mp-r1

uboot-2023.04v is not yet supported on STM32MP1 platforms.

See STM32 MPU ecosystem release note
