Other Parts Discussed in Thread: TMP75, INA226
Hi TI team,
we are expecting to setup the fixed-link 1000Mbps with the external device for MCU CPSW2g port. Here we find the external device can be setting up correctly for RGMII ports. But we find the MCU CPSW2g ports tx clock still output 25 MHZ frequency in this mode, by using Linux device tree configuration. We want to know if there have some methods to change the MCU CPSW2g port status to establish with RGMII setting of external device?
Because this is no auto negotiation function with the two connected ports we only use 1000M fixed-link with RGMII, so should the clock be only drived by any side for transporting the data? Or we should setting phy mode for external device to make this work?
Any suggestion would be welcome.
Thanks,
yong
