How to send/receive Ethernet packets in STM32MP157

[inkong]

Hi,

I want to send and receive data using Ethernet.

I tried this Linux version code, but it didn't works. https://gist.github.com/austinmarton/1922600 

After I failed to try, I found this header code, STMMAC.

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/net/ethernet/stmicro/stmmac/stmmac.h  

Should I make a program based on this code??

I've searched a lot, but I couldn't find any related cases.

I'm not good enough to make the whole program code.

If you have any relevant content or examples, please let me know....

Hi @inkong ,

Not sure to get your question 

Ethernet can be manage by OpenSTLinux

refer to How to configure ethernet interface - stm32mpu 

Ethernet overview - stm32mpu

If you want to generate data over the ethernet port (just to validate or something) you could use for instance command line from linux (e.g. wget)
https://linux.die.net/man/1/wget

To download an image in an endless while loop for instance:

while [ 1 ]; do wget https://cdn.kernel.org/pub/linux/kernel/v6.x/linux-6.1.42.tar.gz; done;

 (it will do forever (untill stopped) a download of the kenrnel archive in tar.gz format, which is ~200 MB of size. )
