Hello!
Recently I had problems with ping to my STM32 + LwIP + DP83848 + RMII. But the latest FW version 1.27.1, it works very well! But now I have problems with HTTP. Follow me and I show you how to create this bug.
First of all I'm using:
- STM32CubeIDE 1.10.1
- STM32F407VGT
- FW 1.27.1
To reproduce this bug, do the following steps.
- Step 1: Enable RMII by going to ETH -> RMII (Rx Buffer length 1524, MAC address 00:80:E1:00:00:00, Rx Mode = Interrupt, NVIC settings = Ethernet Global Interrupt)
- Step 2: Go to FREERTOS and enable CMSIS V2 and go to Task & Queues. Change the Stack Size (Words) in defaultTask from 128 to 1024.
- Step 3: Inside CMSIS V2, go to Advanced settings and set USE_NEWLIB_REENTRANT = Enabled. Leave everything else as default.
- Step 4: Go to LWIP and enable it. Set LWIP_DHCP = disabled in General Settings and then write in the fixed IP address. In my case it is 192.168.1.35.
- Step 5: Inside LWIP, go to HTTPD and set LWIP_HTTPD = enabled. Inside LWIP go to Key Options and set MEM_SIZE = 10*1024. Leave everything else as default.
- Step 6: Download the FSDATA.zip folder and extract it.
- Step 7: The FSDATA.zip folder contains a folder called FS and makeFSdata.exe. The makeFSdata.exe file will create a file called fsdata.c. Click on that.
- Step 8: When the makeFSdata.exe file have created fsdata.c then rename fsdata.c to fsdata_custom.c.
- Step 9: Place fsdata_custom.c at \Middlewares\Third_Party\LwIP\src\apps
- Step 10: Right click fsdata_custom.c -> Resource Configurations -> Extract From Build ... -> Select All -> OK.
- Step 11: Compile the project to your STM32 board and then ping.
OK! It Working great!
- Step 12: Download HTTP_Server.zip and extract it into the projects src folder.
- Step 13: Write this into your main.c file
#include "HTTP_Server/httpserver.h"- Step 14: Add http_server_init(); to
/* USER CODE BEGIN Header_StartDefaultTask */
/**
* @brief Function implementing the defaultTask thread.
* @param argument: Not used
* @retval None
*/
/* USER CODE END Header_StartDefaultTask */
void StartDefaultTask(void *argument)
{
/* init code for LWIP */
MX_LWIP_Init();
/* USER CODE BEGIN 5 */
http_server_init();
/* Infinite loop */
for(;;)
{
osDelay(1);
}
/* USER CODE END 5 */
}- Step 15: Compile and go to your web browser and type in 192.168.1.35/index.html. No web site is displayed. Also if I ping now, then I get no response....BUT....if I restart the processor, then ping, the ping is working. But as long I don't go to the 192.168.1.35/index.html website, my STM32 processor have connection to the DHCP server and I can ping it.
Question:
Why does this happen?
I have followed this tutorial 100% (except that he are using another processor) https://www.youtube.com/watch?v=haO8_eLIDeI&ab_channel=ControllersTech
This must be a bug, becase in FW 1.27.0 version, I had problems with ping my processor. In FW 1.27.1, the ping works like a charm. But now FW 1.27.1 resulting that my HTTPD won't work.
Thank you.
Yes. Now it's working.
I tried both with FreeRTOS and without FreeRTOS. With FreeRTOS, the connection was slow, or sometimes my webbserver did not responds. It was due to threads doing something else. Sometimes it works, sometimes not.
But without FreeRTOS. I just only need to write this code in main.c file
/* HTTP Deamon */
httpd_init();
/* USER CODE END 2 */
/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
{
/* USER CODE END WHILE */
/* USER CODE BEGIN 3 */
MX_LWIP_Process();
}
/* USER CODE END 3 */
}
By replacing Ethernet MAC onto RAM instead of FLASH. Is this a bug in STM32CubeIDE firmware for STM32F407 series?
Thank you so much.
Great!
Also fix this. I can only select "fsdata_custom.c". Looking forward for Week 23 this year. Thank you so much 🙂
