STM32MP135F-DK - Netx Duo WebServer - unable program application to STM32MP135F-DK

[ravo]

Dears,

I am able to compile Nx_WebServer demo. But when I try to run/debug it will halt.

I read all notes in NetXDuo/Nx_WebServer/readme.html - the last chapter "How to use it ?"

• Open your preferred toolchain
• Rebuild and run DDR_Init example to initialize the DDR memory
• Rebuild all files and load your image into target memory
• For STM32CubeIDE, in order to keep DDR initialized, please remove “monitor reset” line in “Debug Configurations->Startup>Initialization Commands”
• Run the application

But I end on red line - unable load image - Where could be problem ?

I am able to compile and debug another aplication ftom STM32Cube_FW_MP13_V1.0 like UART, ADC examples withou error.

Error in final launch sequence:

Failed to execute MI command:

target extended-remote localhost:3333

Error message from debugger back end:

Remote communication error. Target disconnected.: (undocumented errno 10061).

Dear @ravo 

I do not reproduce this error at my end in running this particular example after following the readme file.

This typical error msg usually indicates that 

1- you haven't run the DDR init example prior running the NX_webserver project

2. you haven't changed the NX_webserver/debug properties as mentioned in the readme file (please remove “monitor reset” line )

Board boot pins must be set in "Engineering boot mode" But you said you were already familiar with other HAL examples so I don't think this was your issue.

Dear @OlivierK ,

Thanks for answer.

As I wrote earlier I have already run DDR Init, and monitor reset lin in debug prop in startup section was removed. But how to verify if it is running ok?

Maybe I do something wrong here:   

Rebuild all files and load your image into target memory

I am doing it using STM32CubeIde with Debug command, is it ok?

Small update,

I have looked that blue led is blinking (after DDR_Init - but only when it is running in DEBUG mode, when RUN then nothing...)

Then I am able to start DEBUG for NETX Duo application... But then it will show warning...

When I push Resume button, then it will start... 

I got info in UART that project is running. But unable to continue...

When stop and restart debug once more it will never send data to UART...

May I doing still something wrong ?

Regards

Hi @ravo 

Yes, CubeIDE projects are made to be debugged directly in Engineering mode by plugging a stlink usb cable,

I use the bug button to enter debug:

• Rebuild and run DDR_Init example to initialize the DDR memory

It means you need to run the DDR_init example first, if properly done you should see the blue led toggling (DK-board) indicating the DDR is properly initialized. Once there, you should quit the DDR init project without resetting the board.

• Build the Nx_WebServer_A7 project as is.
• Modify the Nx_WebServer_A7 project debug configuration ( remove "monitor reset")
• Enter debug.

Regarding the projet build itself, there is nothing to change it works as is. If you want to enable the  Nx_WebServer_A7 debug symbol  you can modify :

• Nx_WebServer_A7 project properties/ C/C++ build/Settings/MCU GCC Assembler/Debugging -> Debug level Maximum.
• Nx_WebServer_A7 project properties/ C/C++ build/Settings/MCU GCC Compiler/Debugging -> Debug level Maximum.

Regards,

Olivier

Dear @OlivierK 

thanks for your comments.

Really I must do "Rebuild and run DDR_Init example to initialize the DDR memory" every time prior to start new debug session for Nx_WebServer application ?

I only receive "Nx_Webserver application started.." in UART terminal

nothing else... 

So I tried adding more debug prints... and I see that all initialization is done successfully.

Can I define specific IP address instead using DHCP ?

Best regards

Second update.

I found how change to static IP:

In file Applications/NetXDuo/Nx_WebServer/NetXDuo/App/app_netxduo.c 

line 175:

ret = nx_ip_create(&IpInstance, "NetX IP Instance 0", STATIC_IP_ADDRESS, MASK_IP_ADDRESS, &EthPool, nx_stm32_eth_driver,

pointer, 2 * DEFAULT_MEMORY_SIZE, DEFAULT_PRIORITY);

when define:

#define STATIC_IP_ADDRESS IP_ADDRESS(192,168,0,2)

#define MASK_IP_ADDRESS IP_ADDRESS(255,255,255,0)

Then when I try ping board it answer correctly. So application is running and it is connected to network

But still no mor logs... is it normal ?

I copy content of ..\Applications\NetXDuo\Nx_WebServer\Web_Content\ to root of microSD formated as FAT.

But I only get ping response, unable to get running web server on http://192.168.0.2/

I have read readme.html once more... but I can't find where is the error.

Thanks in advance for your help.

Hello @ravo ,

It seems you have the same DHCP server problem to provide the address as the other post.
https://community.st.com/t5/stm32cubeide-mpus/nx-iperf-a7-unable-run-tcp-test-both-client-server-and-udp/td-p/634463

Did it work well now?

Dear @DBELL.1 

Yes you are correct, now the application is running normally. But I have some notes:

(1) When opening http://IP@/about.html is OK as it was written in readme.html. But there should be better to retarget from http://IP@/ or usage index.html for better usage.

(2) And for last How to setup NetXDuo to use static IP address ? As I wrote in previous post. I am able to start using:

ret = nx_ip_create(&IpInstance, "NetX IP Instance 0", STATIC_IP_ADDRESS, MASK_IP_ADDRESS, &EthPool, nx_stm32_eth_driver,

pointer, 2 * DEFAULT_MEMORY_SIZE, DEFAULT_PRIORITY);

when define:

#define STATIC_IP_ADDRESS IP_ADDRESS(192,168,0,2)
#define MASK_IP_ADDRESS IP_ADDRESS(255,255,255,0)

But then NetXDuo application did not work correctly (only ping response)

What could be here wrong...

Hello @ravo ,

Further in the code, in the same function, there are:
ret = nx_dhcp_create(&DHCPClient, &IpInstance, "dhcp_client");
and
ret = nx_ip_address_change_notify(&IpInstance, ip_address_change_notify_callback, NULL);

and in App_Main_Thread_Entry():
ret = nx_dhcp_start(&DHCPClient);
where the address is set.

That's why your modification shouldn't be taken into account.

regards
David
