I am using STM32H573 and trying to enable ethernet. I have used the below article for it:
https://community.st.com/t5/stm32-mcus/how-to-use-the-lwip-ethernet-middleware-on-the-stm32h5-series/ta-p/691100
But ethernet is not being initialized. The HAL_ETH_Init is returning error which is resulting in error handler.
This is the condition being checked in MX_ETH_Init function. As even after using the steps mentioned in the article mentioned above the ethernet is not working.
- Do we have to add RX and TX descriptors specific addresses in the linker file?
@mbarg.1 I have tried that but still it is not working.
This where it is getting error inside the HAL_ETH_Init function. Moreover, there are no LWIP examples on STM32H573.
Look at examples for H563 - H573 is the same with minor differences on encryption hw that does not impact Ethernet, it is due to export limitation on some crypto hw - select ETH and ...
some examples where to learn how to setup your micro.
Kudos and solution ok mark are appreciated.
