Hi team,
My customer Marelli use 812s in their lighting domain control projects, and have some questions maybe need your help. Thanks!
- Is it possible to complete the automatic setting of the entire RMII mode through autonomous operation?
- Do I need to reset before and after autonomous operation?
- For the read operation of the 0x18B register, the read data (0x1C4B) is not same with the indicated value in the register map.
- Read/write steps: 0xD 0x1F; 0xE 0x18B; 0xD 0x401F; read/write 0xE. Is there a problem with the operation?
- There is the same problem when reading and writing other MMD1F registers.
- When configuring RMII mode, can it be set only for RMII_CTRL_1 Register and RMII_OVERRIDE_CTRL Register? Need to manually disable some related registers in other modes?
- Current setting step
- PHY HW Reset
- autonomous operation(addr0x18B,data0x0040)
- Set Mode: Slave(addr0x1834,BIT14=0)
- RMII CTRL Register Setup(addr0x648,BIT5,6=1)
- Current setting step
- Do we have some configuration step for RMII mode?
