Webserver on lwip. If LWIP_HTTPD_DYNAMIC_HEADERS is enable, the webserver is not working correctly?

[itechtv]

I have a question that has been bothering me for a long time!

lwip 2.12 webserver it has problem with LWIP_HTTPD_DYNAMIC_HEADERS.

When enabling LWIP_HTTPD_DYNAMIC_HEADERS, I get unstable work, sometimes it works, sometimes don't work. 

When disabling LWIP_HTTPD_DYNAMIC_HEADERS, we get an error "Assertion "HTTP headers not included in file system" failed at line 2271 ...

I use NUCLEO-F767ZI and STM32H743

The problem is observed in all versions of stm32CubeIDE 1.9.0 by stm32CubeIDE 1.11.2

But stm32CubeIDE 1.8.0 everything work well.

Could someone help?

Hi,

I tested the application LwIP_HTTP_Server_Netconn_RTOS available in the official STM32F7Cube Firmware v1.17.0 with LWIP_HTTPD_DYNAMIC_HEADERS Enabled & Disabled.

Both ways the application works properly.

PS : the last LwIP version used on STM32 is V2.0.3 and due to the fact that we switched to NetXDuo as TCP/IP stack, we do not plan to maintain and update the lwip stack.

Except that on Github and in CubeMX there is v2.1.2.

The Ethernet in CubeH7 before the v1.10 was basically dysfunctional.
