STM32 Ethernet #50618

Closed Bamelink closed 2 years ago

Bamelink commented 2 years ago

Has someone got an example for using ethernet/UDP on STM32 MCU?.

Description

Hi, I am working on a project for Formula Student and I would like to use and push Zephyr with MicroROS. But I am currently stuck on getting ethernet up and running. We have made a custom board around the STM32F407VGT6, but it is very similar to the olimex_stm32_e407 and I can already flash some examples with this board by modifying it's configuration.

What I am not able to achieve is getting ethernet to work with Zephyr. We had our custom ehternet driver in FreeRTOS (which to this point could only send) so we know that it works on this board. I am fairly new to Zephyr and I think my problem lies in the prj.conf.

Has someone got an example?

My question is, whether someone has got an example for the configuration? I have my mac node in the dts with the according pins. I tried some examples like the net/socket/echo sample and added the following to the prj.conf: CONFIG_ETH_STM32_HAL=y CONFIG_NET_L2_ETHERNET=y Is there anything more I need to do? We do not have UART or USB on this board, so console output is hard, but going though the debugger after reset gives the output I have put below. I think it crashes in the init before main even runs. At least it interrupts and goes into a idle loop. As I said, things like blinky etc. work.

If you have a segger, you can enable the RTT log/shell backend and use that. Without a UART to display logs, you're going to be playing pin the tale on the 18km2 donkey. You can take the existing network samples, https://github.com/zephyrproject-rtos/zephyr/tree/main/samples/net/sockets and try those on your board to see if networking is working. Then, if it does, use those prj.conf files as a base for your prj.conf file
