KSZ9567R: host port in RMII mode #80

Closed embeddman closed 1 year ago

embeddman commented 2 years ago

Hello!

Is it possible to use host port in RMII mode? I'm using SAMA5D36 CPU, it has EMAC 10/100 and GMAC 10/100/1000. I can't use GMAC, that's why I'm asking. Also EMAC 10/100 doesn't support IEEE1588.

MII/RMII/RGMII interface is hardware issue and the chip needs to be strapped for proper operation. The register 0xN301 specifies the mode. The RGMII delays cannot be strapped so it requires software to write to this register to work. If strapping cannot be done software can be used in the last step to configure this register. KSZ9897 and similar chip have been used with MII and the second RMII MAC in the SAMA5D3 board.
