This is fully function TCP client - chibios 18.2.1 lwip 2.0.3

Hi,

No matter. I am not found satisfactory answer in thread "user projects". One post about client side, but any answer.

I will try to find some problem on my side and at the same time i will wait for some next advice, experiences or some fully operational client-example.

thx Nojwa

Hi Giovanni,

i know. I tried demo for F4, but this demo is for server side. Demo is fully operational.

Now i write client side, but can't make a operational connection.

Exists somewhere example for TCP client over lwip (ST's family)?

Connection to the server server failed err_t == -4. Wireshark didn't detect any request for connection to server (to pc ip: *, *, 6, 110).

Have you some experiences? Some lwipopt for tcp client ... anything?

Error output:
[018.434 ...

My test program end with err_t == -4.

Yes, it was right way.

As the first thing i try the kit for STM32F207 and the demo for ST_STM32F2_DISCOVERY was fully operational.

For my board it was necessary to modify settings of pins on port in board.h. Demos are funcional.

Thx you for support

I agree, it's very abstract description. I known, that PC changing posistion, so program is running.

I have my own board, unfortunately I don't have a kit. Boards should be compatible.

I don't known, where is problem. I'll try to get the kit and load the demo.

I'll be back when I have a kit.

I have problem with demos for STM32F207xE.

I compiled both demos for F207xG, loaded to my board, but nothing happens. Leds not blinking and serial line is dead. No data send it to console.

All my changes are: ld script change flash size to 512K (STM32F207xG.ld), target for my led is on GPIOE (4 ...
