Part Number: DP83TC812EVM-MC
Other Parts Discussed in Thread: DP83TC811

Hi Team,

We are trying to integrate DP83TC812 automotive ethernet with NVIDIA Jetson AGX_ORIN 's RGMII interface . We checked for the existing driver support of dp83tc811 but couldn’t see the driver prints while booting .
L4T-VERSION - 35.3.1
Earlier, we have bought up RGMII interface( PHY chip -88E1512) in AGX_ORIN ,with that the following changes are performed :

  1. Added configuration for DP83TC811 in the config file (CONFIG_DP83TC811_PHY=m)
  2. Added debug prints in dp83tc811_config_init function .
  3. Compiled and cross checked the configuration in .config file ,modules and flashed the device
  4. While booting,the driver is not loaded automatically(checked by lsmod) and couldn’t see the driver prints in the log
  5. Also we took dp83tc812 driver from TI-page,but the observation is same .

Sharing porting guide, will be helpful to proceed further .
Kindly check and let us know the steps to follow/handle .

Thanks and Regards,
