Hello @STea .Thank you for your answer. I modified the part (line 1212 of stm32h7xx_hal_eth.c) as you suggested, tested and compared.I got desired performance.The result when the code is not modified The result when the code is modified. Thank you ...

Hello @STea . When you were testing, did you clean and rebuild the project?In my case, I could see the same UDP performance when I simply built the code generated after changing the FW version from CubeMX. However, when I cleaned and rebuilt the proj...

Hello @lee_daeun . I don't know if you intended it, but there seem to be a few problems.Despite using Tim6_Flag_500ms in while(1) {} in main, additional HAL_Delay(500) is used.Since there is no code to clear Tim6_Flag_500ms to 0, once Tim6_Flag_500ms...
