TSE phy-less is not possible ??
- 6 years ago
Phy-less is possible.
This is what we I did to solve this issue:
1. In software: seems that internich can output network even if it
detects any phy , yet we forced in getPhySpeed routine to configure
the TSE controller to 1000 (the default in interniche code is 100, so
we had to change it)
2. switch is used in "unmanaged mode", i.e. it is enabled and
configured "automatically" with default configuration (marvell
default) on power.
Yet, The actual problem was with RGMII delay (clock need to be phased
shift from data, this could be solved by adding delay in fpga or in
switch. We solved it by configuring the marvell switch rx delay bit
(it is called"rx" in switch but it is actually the tx from fpga -
through switch - to the output network).
Now everything works !
Thank you very much ,

Hello,
PHY is needed to complete the ethernet protocol. MDIO is the component that will help to configure the PHY and generate the needed clock/s by TSE. If this connection (MDIO) is missing, this means you missed the configuration of the PHY, and you will not be able to get any link.
The only option that might help you to not use the PHY would be the internal loopback test; usually processor > MAC > processor again. This is a mechanism to test the system and make sure it is sending and receiving data.
Thank you,
