AM625: RMII Speed Slow

Part Number: AM625

Tool/software:

Hi TI Experts,

Based on the below thread, customer now could link up & ping on their own AM62x board using RMII.

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1440535/am625-how-to-configure-rmii-mode

However, customer found the Iperf 3 speed is quite slow than the expected 100MHz shown below.

I searched some previous E2E threads, and I am thinking maybe we need two check the below two registers.

The Synce_Sel Clocking for CPSW_SS_SYNCE_MUX_REG

The Speed & Auto_Speed_En for CPSW_PN_SPEED_REG_k

However, I could only find the register description in the AM64x TRM, but could not find it on AM62x TRM.

May I know the register & register address for CPSW_SS_SYNCE_MUX_REG & CPSW_PN_SPEED_REG_k is the same in AM62x?

Apart from this, do you have any other suggestions to improve the low speed in RMII situation?

Many Thanks,

Kevin
