Ethernet support on STM32F479ZG/ZI

I'm working with STM32F479ZG and ZI both have working ethernet.

In the lastest CubeMX 5.1.0 it shows that those MCUs are not supporting ethernet.

Is there a work around for this issue?

Dear All,

I come back to this old discussion to precise that Ethernet is not fully supported in STM32F479V/Z/A as well as STM32F469V/Z/A. That is why STM32CubeMX will not be updated (contrary to what I previously said).

Sorry for such confusion. This post comes to discard previous one.

​Hello @MPetr.17​ 

This's not an issue,  this MCU do not support Ethernet as it's indicated in the Datasheet.

Best Regards,

Khouloud.

Something must be wrong here.

It has been taken just a second ago from your site.0690X000008AlFpQAK.png

Also I have a working Ethernet on this MCU, I just need the CubeMX to create a sketch of the MCU and its occupied pins.

​@MPetr.17​ 

Those informations are generic  ( about STM32F479xx devices) , for specific information you need to see the Datasheet.

Best Regards,

Khouloud.

Also, here is a manual for it.

It does support Ethernet otherwise my Ethernet would not be working!

You need to select STM32F479I/B/N device, not STM32F479Z.

But we use the Z version of the MCU and it does support Ethernet!

You insist that it doesn't because someone made a mistake and wrote in some document that it doesn't.

It does work, we have 3 different board designs with the STM32F479ZG/I all of them have a working Ethernet...

Only the Z version has the right 144 pins that we use.

The I version has 176 pins

The B version has 208 pins

The N version has 216 pins

Those versions will create the illusion that we have more free pins than we actually have.
