Portable gcc rp2040 does not compile in vscode, it claims it cannot find the portable

carlosdelfino · February 6, 2025, 3:31am

I have been trying for a few days to use the portable GCC_RP2040 in a project created with the VSCode extension, but I have not been successful. I have tried several times, I have reviewed the file, but something is missing to make it work correctly. I am learning how to use cmake, but I already have a little experience with FreeRTOS.

Below are my configuration files and the error messages I have received.

Hi @carlosdelfino

Welcome to the FreeRTOS Community Forums !

I see a couple of potential issues in the CMakeLists.txt file. You can try changing these and check if it works.

FreeRTOS usually doesn’t have a FreeRTOS_Kernel_import.cmake. Is this path correct ?

include(${FREERTOS_KERNEL_PATH}/portable/ThirdParty/GCC/RP2040/FreeRTOS_Kernel_import.cmake)

If the above path is correct, you need to place this line before adding the subdirectories.

include(FreeRTOS_Kernel_import.cmake)

add_subdirectory(${FREERTOS_KERNEL_PATH} freertos_kernel)
add_subdirectory(${FREERTOS_KERNEL_PATH}/portable/ThirdParty/GCC/RP2040/)

You don’t need to add portable/ThirdParty/GCC/RP2040/ as a separate subdirectory.
The portable directory should already be included when adding FREERTOS_KERNEL_PATH. Remove this line

add_subdirectory(${FREERTOS_KERNEL_PATH}/portable/ThirdParty/GCC/RP2040/)

You can use this as a reference

I cleaned up the CMakeLists.txt file based on the example you gave me, although it doesn’t give any errors, cmake isn’t generating the files for ninja to run. I’m not very familiar with cmake, and this parameterization is proving very difficult. The project that was the basis for this new one works, it compiles without any problems. But there’s something missing in this one that I can’t see.

Here’s the updated file:

To make things easier, I placed the project’s base code at github @ ArvoreDosSaberes/magnectostricao/tree/freertos, this latest fix is not yet available in this repository.

I made new adjustments, and got a slightly better result, but it still doesn’t compile, I get the following output during compilation, also follows the current CMakeLists.txt.

Let me know if this fixes the issue for you and if this is the expected result.

This change only changes the source from where I get the freertos, I use it this way because I have a slow internet speed, so I download it once from a local central repository, and from there I download it to the other working repositories.

Thanks for trying.

carlosdelfino · February 7, 2025, 4:43pm

I made several adjustments, and after a lot of fiddling, I managed to compile, but nothing worked.

It executes the functions of creating each task (xTaskCreate) and when I start the Scheduller (xTaskStartScheduller) it freezes. It doesn’t call the tasks.

The code is at github at ArvoreDosSaberes/magnectostricao/tree/freertos_nova_abordagem (Branch freertos_nova_abordagem)

I had to change a line in freertos to compile, but I believe that this may be blocking the start of the scheduller. Although the changed code is related to the interaction between cores, and I’m only using one core.

My deadline is approaching, I need to hand in my TCC this Sunday, and I don’t know what to do anymore.

karahulx · February 7, 2025, 5:06pm

Is it possible for you to attach a debugger and check where the code is stuck, after the scheduler is started?
Also make sure configASSERT is enabled in FreeRTOSConfig.h file to see if it is stuck in any Assert

carlosdelfino · February 7, 2025, 5:32pm

Caro RAHUL KAR,

Unfortunately, I don’t have the means to use a debugger. I’m working with the RP2040 board, and I don’t have many resources available for it here.

Atenciosamente,
Carlos

karahulx · February 7, 2025, 5:41pm

Okay, just an additional step you can try out. I see all the tasks are created at Idle priority = 0 and configUSE_TIME_SLICING is set to 0. So none of the tasks will be preempted, because none of the tasks call YIELD function. You can try setting configUSE_TIME_SLICING to 1, to see if that makes a difference or have the tasks at different priority.

carlosdelfino · February 7, 2025, 6:13pm

I changed two tasks, one common and the one that controls the LED display, which should clear the display and display the message “Signal Level”, but nothing happens.

About the yield, they are very short tasks, and I am using vTaskDelay which would give enough time for other tasks to be executed. I also corrected the values, as they were supposed to be in milliseconds.

carlosdelfino · February 7, 2025, 6:24pm

I just put one task and it freezes.

karahulx · February 7, 2025, 6:41pm

Just an additional query - Have you verified if the task creation is successful ( you can check by the return value of xTaskCreate ) and the configMINIMAL_STACK_SIZE is enough?

carlosdelfino · February 7, 2025, 6:47pm

I haven’t checked, but I checked now, and it is creating.

An indication that the rp2040 freezes is that to save the firmware update I need to reset it with the boot button pressed. When it is running the firmware correctly this is not necessary.

karahulx · February 7, 2025, 6:56pm

Since there is no debugger attached, its hard to ascertain exactly what is going on.

I would try a smaller snippet of code, like

#include <stdio.h>
#include "FreeRTOS.h"
#include "task.h"

void vBlinkTask(void *pvParameters) {
    while (1) {
        printf("Blink Task Running!\n");
        vTaskDelay(pdMS_TO_TICKS(1000));
    }
}

int main() {
    stdio_init_all();
    
    xTaskCreate(vBlinkTask, "Blink", 256, NULL, 1, NULL);
    
    vTaskStartScheduler();

    while (1);
}

to see if it works, if yes, then other parts of your code might be causing the issue, if this also fails, we can check further in FreeRTOS ?

The problem is in my code, blink worked.

I’m trying to adjust the stack size, I’ll open a new post for this issue, I don’t know how to size the ideal stack, I’ve always used the default and it worked.

I tried using three times the minimum size, but it didn’t work, so it can’t create all the tasks, I made an adjustment according to possible demands, but it keeps crashing.

The funny thing about all this is that the task (task_tinyML) that I tested in isolation, only it, has no code running in it, only the delay. It shouldn’t freeze.

Okay, glad we isolated the issue atleast.

If you are using task_tinyML using the start_tinyML function, one issue might be you are using strcpy.

strcpy operates byte by byte, and depending on the implementation, it may use stack-heavy optimizations.

Try removing all the strcpy operations to see if that solves the issue. You can use memcpy as an alternative, if it fits your design.

Everything indicates that the problem is in task_display_oled, it needs a larger stack than normal, I made the adjustment that you suggested when using memcpy, but I still need more stack, I tried to find in the freertos configuration, where I can increase the stack limit for the sum of the threads, because adding all the threads I can’t use the stack.

Since you are using dynamic allocation, you can try increasing configTOTAL_HEAP_SIZE ( currently 4KB ) for allowing multiple threads to be running simultaneously.

Now it is creating all the tasks, but it is not switching between them, they are all at the same level, one level above idle.

I have already used taskYield() and vTaskDelay() and vTaskDelayUntil, but they do not switch.
