This is an umbrella topic where I will collect the key problems and solutions to finally get networking on STM32 working. The issues formatted as bold are the most critical ones.
HAL ETH drivers have been significantly reworked since the following firmware packages: CubeF4 v1.27.0, CubeF7 v1.17.0, CubeH5 v1.0.0, CubeH7 v1.10.0
Series: F1, F2, F4, F7, H5, H7 (all STM32 with Ethernet)
Series: F1, F2, F4, F7 (older Synopsys basic peripheral)
Series: H5, H7 (newer Synopsys QoS peripheral)
Series: F7, H7 (Cortex-M7 CPU)
lwIP API related:
Other related information:
Another detailed topic by @alister: "[bug fixes] STM32H7 Ethernet". While mostly dedicated to H7 series, it also has a good amount of information relevant to all Ethernet/lwIP related development.
Open source zero-copy Ethernet/lwIP driver example. The hardware driver is for F2 series, which means that it's almost the same for all Fx series. The lwIP related code and general ideas are still valid for all series.
My other closely related topic: "Actually working STM32 Ethernet and lwIP demonstration firmware". As that topic is currently unavailable, because ST still has not moved it to the new forum, I am attaching a PDF copy of that topic and the related firmware files to this topic.
Solved! Go to Solution.

Dear community members,
Thank you for your continuous support and feedback to identify potential issues related to Ethernet. The input provided in this conversation thread has helped us to improve the solution from HAL drivers examples and documentation perspectives.
As many of the mentioned issues have been fixed, we wanted to give you a status update (see below). We are aware that some issues persist, and we will continue the analysis to provide solutions. In the meantime, if you have further feedback, please let us know, and don’t hesitate to start a thread if you encounter an issue that has not yet been mentioned here.
Thanks,

Status |
Implemented in the new HAL_ETH_Driver. Refer to the thread Ethernet HAL Driver reworked by ST and available in 22Q1 (preview now available on GitHub) for more details about some of the applied fixes. (1) |
|
RMII mode not enabled because of lacking SYSCFG synchronization. |
|
Many flaws as a result from *** porting of the reworked H7 series HAL ETH driver. |
|
Unnecessary delay in LAN8742_Init() and link state management in low_level_init(). |
Questions answered |
Unnecessary delays and peripheral reset in HAL_ETH_Init() function. |
|
Fixed in STM32CubeMX-6.9.0 |
|
FIXED IN STM32CubeF7 v1.17.2 |
|
Fixed mismatch in linker section names between linker file and source file. |
|
resolved in the STM32CubeH7 V1.10 |
|
Main reported issues fixed- Some enhancements are required |
|
Poorly chosen MDC (MDIO) frequency limits and scarce documentation. |
Documentation internally updated. 133712 (used for internal reference only) |
Move bufffers of fsdata_custom.c file from Flash to RAM. In v1.28 of Stm32cubeF4 |

|
Flawed MPU configuration and D-cache maintenance in lwIP driver. |
Fixes applied on Lwip projects in STM32CubeH7 v1.11.2 |
Investigation ongoing. We will update you case by case in this post. |
|
ETH_DMACSR_RBU error occurs and stalls the Ethernet receive on STM32H7. |

(1) the reworked Ethernet driver is available for:
STM32CubeF1 and STM32CubeF2 don’t get a reworked Ethernet driver.
These updates are available From CubeMX version 6.4.0 and higher and we recommend using the latest tools and software versions to make sure latest fixes and patches are applied.

As the main topic has hit a 10000 character limit, I'm changing this message to a list of fixed issues, which many people will still find useful.
Series: F1, F2, F4, F7 (older Synopsys basic peripheral)
Series: H7 (newer Synopsys QoS peripheral)
Series: F7, H7 (Cortex-M7 based)

Hi @Piranha ,
Needed follow-up actions for each discussion are tracked internally by me & Imen.
I suggest to close the current question.

Hi Piranha,
Thank you very much for the information.
If I may please ask why you don't share the sources ? I will try to do the modifications for H7.
Thanks

Can anyone send example project ? thanks so much Cubemx 5.4

My fixes and improvements to ST's STM32H7 ETH driver and lwIP ethernetif.c are at https://community.st.com/s/question/0D50X0000C6eNNSSQ2/bug-fixes-stm32h7-ethernet.
Source code and documentation attached.
I don't use evaluation boards or build example code.
You'll have to port my changes yourself.

Thank you @Piranha for this detailed write-up! I've updated the original thread to point to this one. *excellent* information and lots of detail.

I am attempting to get Ethernet work on an STM32H745 on the M7 core currently. But I am using CubeIDE 1.4.2 and CubeMX 6.0.1 with ver 1.8.0 of the H7 firmware package. Since these are a bit newer, it is unclear to me which of these issues are still present and which still need fixing. Does anyone have any updates that apply to the newer stuff?
2020-09-01 11:17 PM
Yes, I think same as you. It is worthy to make it clear which ones have remained until now.
