stm32f407 Lwip without FreeRtos

[MHama.3]

Hello community

I am working with the stm32f407 on a Project with Lwip without FreeRtos. The code worked on version 1.7.0. but when i changed to 1.9.0 I got hardfault, I solved the problem by putting the LWIP_RAM_HEAP_POINTER on address 0x2001C000(SRAM2). but I still can't ping the board. 

The LWIP_RAM_HEAP_POINTER on 1.7.0 could not be set at all in the MX configuration.

Does anyone have any idea.

many greetings

Hello MHama.3,

I have same problem. Did you solve the pinging problem?

Hello MHama.3,

I solved the pinging problem.

I disabled CHECKSUM_CHECK_ICMP and CHECKSUM_GEN_ICMP in the Cube Mx LWIP configiration checksum tab. Then pinging is ok.
