DV 08:47 PM PCB Development: RE: RGMII Voltage Levels

Hi Lucas,
You are correct the RGMII interface on the SOM is hardset to 1.8V, which wouldn't be able to interface with a 3.3V PHY. In order to interface to a 3.3V level ethernet PHY you need to route one of the HPS ethernet MACs throug... Daniel Vincelette

LU 04:17 PM PCB Development: RGMII Voltage Levels

I'm trying to determine if a alternate Ethernet PHY is okay to use with the RGMII interface of the SOM module. PHY controllers such as the LAN8670 and KSZ8041 tout their single 3.3v supply, so I'm assuming that's the voltage level they u... Lucas Uecker

Good to hear; you're welcome! Zachary Miller

Hi
That works with *socfpga.dtsi* from 5.15.30-lts (and no *skeleton.dtsi* required).
I can now erase, write and read the QSPI NOR Flash.
Thanks a lot.
