Hi there,

did someone ever used the KSZ8081 Ethernet Phy.
I have some of them in use on another Processor Board.

I saw in gitlab that a feq PHYs are already supported.
https://github.com/espressif/esp-idf/tr ... sp_eth/src
The question I am dealing with is if its easier to use/buy a new PHY and have direct support or
or use the existing one I have (KSZ8081) but have more work with Software.

Best regards
Mr.T

Yes, it should be easy to port a new PHY chip to esp-idf, since we already have a lot of template PHY codes there (although they're somehow duplicated). But to make your PHY chip work properly, you'd better read the datasheet of that PHY firstly.
In your case, KSZ8081, should be 99% similar to KSZ8041, maybe you only have to change the PHY chip ID in your code.
