Hi, Cakeslob,
I have managed to run W5500 with 446ZE board. Above all with with your static branch as base. I have attached my little efforts.

Hey Viren, looking good.
Is this a static version of this firmware?

If you are looking for more performance, this is the DMA SPI version that we need to work on adapting to other boards

I have added W5500 to your branch.
github.com/cakeslob/Remora/tree/nucleo_staticZE.

It doesn't have encoder and qei modules. They are must for my Lathe setup.

Ahhh thats a good point Viren. I havent been able to make the firmware work with the nucleo yet anyways. I dont know how easy the QEI will be to add, but perhaps I can try to add software encoder.


Please report back on the performance, I am interested in the results.

Tested with 1 stepper motor x axis.
RPI 3B+, pru_base-freq-80,000.

In PC C2D.
Base ferq 120,000. No joint 0,1 problem,

I have used your modified repo.
I am not succeed in Expartia repo with wiznet.
EMC doesn't comes out of eatop.

Nucleo-ethernet with PC mode video.

Yes, I also compiled and tested with Nucleo 446ZE. Ping is working, and can successfully upload config.txt. So it's working for me.
But stepper not moving joint 0,1 error.
Also Ping .400+.
github.com/Virencq/Remora-eth-static
in this PING .100+

Sorry Viren, Im must have not understood what you were saying earlier. The video you showed me looked like it was moving very fast.

The mbed version is not exactly production ready, more of a proof of concept, Im trying to get the the nucleo going with the other firmware but Im having issues getting it working.

Looking at the difference, you added the stepgen changes but I never tested with that. If you are using the component in the nucleo ethernet repo, you probably need to change this line
github.com/cakeslob/Remora/blob/nucleo_e...eth.c#L541C2-L541C34

github.com/cakeslob/Remora/blob/nucleo_s...Remora/remora.c#L691

Thats what stands out right now.

I'm trying to play with stm32h743 with a lan8720 module but without success in exchanging packets and communicating with linux cnc, would you have any tips on how to configure using CubeIDE?

What repo are you working out of? The nvem and ec500 repos are examples of cube using ethernet PHY. I also struggle with the H7 series, I cant get debugging to work with pyocd. Perhaps share your project, it might be more helpful. I have an H723 with phy I can play with, as this is relevant to my interests.
