USING Ethernet Nucleo-h743zI2

[Ariel1]

HI everyone (:

Im pretty new and im looking for a way to use ethernet on my Nucleo-h743zI2 board.

I Want to be able to send/recieve  "raw" packets from my board and to the pc through ethernet .

Im using the last version of Stm32cube ide

- 1.18.0.  And the last version of mx - 6.14.0

And the STM32CubeH7 - 1.12.1

I saw this long post: 

https://community.st.com/t5/stm32-mcus/how-to-create-a-project-for-stm32h7-with-ethernet-and-lwip-stack/ta-p/49308

And this example: 

https://github.com/stm32-hotspot/STM32H7-LwIP-Examples/tree/main/STM32H743_Nucleo_ETH

Is it still valid for the current ide and mx versions? 

And maybe there is more simple example or refernces that I can look into? 

- Whats the best way to try and run an example that is valid for my versions? 

Thanks alot, 

Ariel

Yes basically this is the situation.

For sending raw packets: unfortunately ST does not provide examples (AFAIK) but you just can start from a simplest LwIP UDP example and drop the LwIP, leave just the ETH and PHY related code.

Of course you can request a custom example, made just for your goal, here.

You think the example will still work with the new versions?

Or there will be many issues? (e.g memory mapping).

Do you have good resources to read about the background knowledge to be able to have a good understanding of the example?

Thanks alot for your quick response.

The updated examples, aligned with current version of the STM32H7 "HAL" and the ETH driver, are available here: https://github.com/stm32-hotspot/STM32H7-LwIP-Examples

You can skip the long reads (as you're going to drop the problematic LwIP layer anyway) and start from one of these examples. The only hitch is that (for historic reasons) the RTOS-less or 'bare metal' examples used the ETH API variant with polling, and RTOS based examples use interrupt variant (_IT). The former variant seems deprecated now. But we just can use the interrupt variant without RTOS as well.

Same about ThreadX/NetX based examples. If you plan to use a RTOS anyway, choose your RTOS and examples developed for it. A small focused ETH test can be done without any RTOS.

About resources: start from quick review of the STM32 reference manual (RM)  on the ETH. The ETH module itself (the IP) is from Synopsys/Designware. Its relatives are very common in other SoC designs, including STM32MP family. The Linux driver for this IP is even known as "stmmac". ("dw" filenames are for Designware)

Thank you alot,

So your suggestion is to just install the old versions of ide,hal, mx and try run the example on it?

Small question about uploading the example. 

I can just  download the example as folder and upload it to for example:

C:\Users\USERNAME\STM32Cube\Repository\STM32Cube_FW_H7_V1.11.1\Projects\NUCLEO-H743ZI\Examples\

Or is a better way? 

[Pavel A.]

Not quite...

- When starting from a certain ready example, use, if possible, the same versions of IDE (compiler actually), libraries and everything else as what was used to make the example. Lesser chance to break it.

Those examples include the HAL library files from version 1.10.0  - just after the major ETH driver rework.

- But later try to move to the latest ST library, as they sometimes manage to fix a bug. Updating the compiler & toolchain is optional.

Version of STM32H7 combined package is now 1.12 but the HAL drivers (sub-repo) and ETH driver version is 1.11.5. 

I recommend to use standalone CubeMX instead of the CubeIDE integrated one, because this gives flexibility. You can install several MX versions side by side, and use them independently from your IDE & toolchains. Standalone MX also has more capabilities than the integrated one.

Thanks alot,

Do you have maybe any link for download the ide in version 1.9.0?

It look likes it dissapeared from the list when trying to get the software.

@Adam BERLINGER, Do you know maybe if there are more updated versions that I can use the example here?

https://github.com/stm32-hotspot/STM32H7-LwIP-Examples/tree/main/STM32H743_Nucleo_ETH

If not a link for the ide and mx would be amazing:folded_hands::)

Thanks alot! 

Ariel.

Old IDE & MX versions are available by request here. Temporarily removed until they fix some issue with the website.

[Ariel1]

Hi thanks!

Im trying to generate the code from the same mx version that used in the example:
MxCube.Version=6.5.0

And getting the following warning:

Can i just ignore it?

Thanks alot!

[Pavel A.]

Hi,

Sorry if the explanations were not clear enough. When you use a ready example - just build the example _as is_ and run it.   Cube is not yet known to generate a project with ETH that work without manual editing :(

It is more complicated that it should be :(
