Hello Oyama,
The ind_comms_sdk_am243x_09_02_00_15 supports Ethernet PHY DP83826B, DP83826E and DP83869. Currently, the SDK does not provide custom PHY driver for the PHY DP83822.
Please follow the below steps to integrate the new custom PHY driver into the CCS project.
1. Create the custom PHY driver source files, in this case CUST_PHY_dp83822.c and CUST_PHY_dp83822.h, based on the sample custom PHY source files CUST_PHY_dp83869.c and CUST_PHY_dp83869.h and adapt it accordingly to the PHY DP83822 datasheet.
2. In the project properties, remove the default define corresponding to PHY used on evaluation board under 'Predefined Symbols'. In this case remove the define CUST_PHY_DP83869=1.
3. Update the custom PHY detect function pointer, in this case CUST_PHY_DP83822_detect, and include the header file CUST_PHY_dp83822.h in CUST_PHY_base.c file.
4. Update the PHY address, and the polarity related defines in ESL_BOARD_config.h file.
Please refer the documentation PHY Configuration.
Kind Regards,
