Hi team,
The chip used by the Soc is the TDA2x, and the dp83tc811r used by phy, which communicates through the rgmii mode.
1. The customer intends to set the TX_CLK divider of the TDA2x to change its frequency to 25 Mhz (current frequency is 500 Mhz), modified the value of register 0x4a0052c0 and found a change in the TX_CLK frequency.
If the customer would like to do the same through configuring dts, what should be done?
2. It was also found that the current Soc state is In-band state, causing the rgmii mode to be "10 Mbps/Half - flow control off" anyway. Is there a lack of what kind of handshake between the Doc and the phy then cause In-band state? Could you also provide the timing of the interaction between the soc and the phy?
Could you help check the question above? Thanks.
Best Regards,
Cherry
