custom STM32F429 board and ethernet

[bschwand]

I mentioned this, but now that discussions are open, I will continue here :-)

I am still confused by the various repositories, and build options.
Should I look into the main remora repo, at the STM32F4 boards, or base things on the NVEM repo since that hardware uses a stm32F2 which is very close ? or look at Remora-STM32

what about the linuxCNC components, which is most up to date Remora-nv
or Remore-eth

or maybe Remora-EC500 which seems more recently active and seems to be an STMCubeMX project unlike NVEM it seems ?

also @cakeslob said STM32F429 is working with W5500, where is that ?

I do not know if on my board I have has a free SPI but it might be an option, however why not use just a PHY over MII or RMII since the F429 does have an ethernet MAC interface ? I was leaning toward using the "proper" ethernet interface as I would have ported u-boot to make updates easy (my board has lots of flash and ram)

Anyway, any input welcome, thanks !

Hi,

Remora-STM32H7xx (https://github.com/scottalford75/Remora-STM32H7xx) is the latest development work and incorporates a lot of the updates made for the Ethernet versions. A potential basis to move all Mbed based Remora versions to a common code base.

I really need to clean up by development repos as they cause some confusion.

Legacy STM32 repos for Ethernet boards: Remora-NVEM & Remora-EC500

Active repo for RT1052 Ethernet boards: Remora-RT1052-cpp

Active repo for RP2040 with W5500: Remora-RP2040-W5500

The thought with a common code base is to have all of these supported in one active repo.

Yes that would be excellent for moving forward. It would also make it all a lot more portable.

Right now I am wary of starting anything as I am afraid I'd end up basing it on stuff that is old or not really worked on. I was also wondering if the project was really active. So at best I will do a few experiments and study the various codebases, but nothing definitive for now. If it was at least branches of the same repo, we can look at history of branch/merge/commits but across repos it a lot more difficult to figure things out.

I am looking forward to a unified repo for all boards with the latest developments :-)

I was reading through that and do not see anything about ethernet, it seems to use SPI for comms with the host ?

BTW, I thought the ethernet code was at least useful to look at in the Remora-NVEM/ -EC500 but now you mentioned Remora-RT1052 I understand that supports the same boards and is more recent, so it would be a better place to look at...

Would be good to have a write-up in the docs or Readme as to what is what, until it's all unified

this is the w5500 thing we work on sometimes. I use if for a different board, but did a version for the octopus f429 for a user
