Hello,I have a project running on an STM32F407VE that is using FreeRTOS and lwIP. I have a working webserver among other things. I want to implement mDNS but it doesn't seem straightforward - never done it before. Does anyone have some guidance or...

I have a project on an STM32F4 that consists of a Bootloader and Main application. Both of these apps read an external Flash to retrieve configuration data. The Bootloader is looking to see if Main had previously uploaded new FW to the Flash and if...

When I enabled SNTP I got an error message that basically said there were not enough timers. When I disabled it, the error went away. I had to add LWIP_SNTP to the define for LWIP_NUM_SYS_TIMEOUT_INTERNAL in opt.h. However, every time I Generate C...

So I have run into this a couple of times. Right now I have one that I cannot find a good fix for.I set SNTP_GET_SERVERS_FROM_DHCP to 1 in CubeMX and generated the project then compiled. It is correctly set in lwipopts.h but in sntp.h and sntp.c it...

I spend a lot of time looking and never could find an easy way to do this. I came up with a solution and thought I would post it.I am using the STM32F407. The F4 series only has one way of calculating the CRC in hardware and that is what I chose to...

So that example was helpful but it just pointed out that there are other things to do and that CubeMX isn't properly configuring some things. Specifically, the netif flag was not set indicating that it was IGMP capable - which it should have been si...

The comments in mdns.c explain what the code is doing - not how to use the code to make it do what I want it to do. For example, what functions need to be called to start it up properly? If that is done (some init call) then do we need to do anythi...

I found the code in the public domain and modified the File I/O slightly to add the CRC to the file.Mike.

It is the STM32F407

Yes I am using FreeRTOS.Here is the error I get:Assertion "sys_timeout: timeout != NULL, pool MEMP_SYS_TIMEOUT is empty" failed at line 190 in ../Middlewares/Third_Party/LwIP/src/core/timeouts.cThis happens when the following line in opt.h has the LW...

mDNS example project

Weird STMCubeIDE debug behavior - global structs showing up as all zeros but the code acts as it they are populated with data as they should be!

LWIP_NUM_SYS_TIMEOUT_INTERNAL does not have LWIP_SNTP in it.

Has anyone else had issues with DEFINES in LWIP not working right?
