I star a thor hardware design with four MGBE , used the AQR113C , and the T5000 module seems only provide four MDIO signal and RST/INT sinal for XFI0 and XFI3 , but can not found the XFI1 and XFI2 RST/INT sinal. so how to assign the XFI1 and XFI2 RST/INT signal on T5000 module?
Unused GPIOs could be used for RST and INT of MGBE Ethernet PHY devices. Please choose suitable GPIOs keeping in mind the power on reset values of the pins used and logic level compatibility with the PHY device.
Update: Ethernet PHY is not supported. Only QSFP is supported for now.
do you mean the MGBE 4lane XFI only can be used as the QSFP? But in the PDG file, MGBE can be used to Ethernet PHYs. What’s the problem? And can they seperate to 4 SFP+ , every sfp+ support 10G rate? What’s the difference between THOR and ORIN in MGBE? Only the VIA PCIE to Ethernet PHY? And can THOR support PCIE Switch?
QSFP28 module is supported. QSFP28 could be used to connect to an external Ethernet switch. Or QSFP28 to SFP28/SFP+ breakout/splitter cables could be used.
Hi Sgursal
In the topic 10 GbE - PHY where we asked for supported PHYs, there was no mentioning that this is not supported. And as stated by 575855328, there is also nothing in the Design Guide that PHYs are not supported. Can you please elaborate?
Thank you.
Apologies for the confusion. As you know, Ethernet PHY is not included in our carrier board design. In HW, it should be feasible to support ethernet PHY on a custom carrier board. However, SW support does not exist as yet for ethernet PHYs and taking this in to consideration the overall status is that it is not supported. There is no reason that it cannot work but you would need to own it yourself until there is update on the support status.
About the Design Guide, it describes the HW capabilities. Software support is covered in Linux Developer Guide.
Thanks sgursal. And I have a another question. Can I seperate the 4XFI lane to four SFP+ , every SFP+ support 10G rate? The four SFP+ connectors directily design in the custom borad but not throught the QSFP28 to tranform.
