About 10Mbps communication of ENET of i.MX6UL

Dear all,

 

Our system uses the 100BASE-TX PHY.

 

When our system is connected to HUB of 10BASE-T, it cannot communicate.

In the case of 10MBps, we understand that ENET of i.MX6UL communicate at 2.5MHz to PHY.

However, ENET outputs data at 25MHz.

 

In the case of 10MBps(2.5MHz operation), should we set the MII_SPEED field of the ENETx_MSCR register in 0x4?

 

IMX6ULRM.pdf(Rev0)

- 23.5.7 MII Speed Control Register (ENETx_MSCR)

- Table 23-2. Programming Examples for MSCR

 

May I have advice?

 

Best Regards,

Yuuki
