How to select STM32H743 lwip's system timebase source?

[span.1]

Good day sir.

ST's EVM�?development software and firmware informations or else are as ​below :

• NUCLEO-H743ZI2​
• CubeMX : 6.2.1
• CubeIDE : 1.1.0.1​
• Firmware package : STM32Cube FW_H7 V1.9.0
• lwip : 2.1.2, raw api without rtos.

After modifying according to the How-to-create-project-for-STM32H7-with-Ethernet-and-LwIP-stack-working setting, currently PC PING to the EVM board�?EVM board as the TCP/UDP client that working fine. EVM board as the TCP/UDP server, after running for a while, PC can't ping the EVM board what a problem with the lwip parameter setting I guess, however that's not my point.

Currently SYS time source of test project is TIM6(1mS measurement from oscilloscope), what If I set the SYS time source to SysTick or else. are there any issues/problem problem occurred when lwip working?​

Update your software! Before CubeH7 v1.10 the Ethernet was basically dysfunctional.

Without RTOS the SysTick is the best and default choice.

good day sir

Currently version of the software ,CubeMX :6.5.0, STM32Cube FW_H7 V1.10.0.

lwip 2.1.2 rawapi withour rtos.

Have any example?
