Unable to build project with FreeRTOS, FatFS and sdmmc_host support for FRDM-K64F

[ishelly404]

Hi,

I am having an issue building a FRDM-K64F project with FreeRTOS, FatFS and sdmmc_host_sdhc support. When I create a new project with these three components included together, I cannot build the project and I get the error:

../component/osa/fsl_os_abstraction_bm.c:86:31: error: conflicting types for 'task_handler_t'

This happens even before I have added any code to the project. I am running SDK version 2.9.0 (and also had this issue with 2.8.1), MCUXpresso version 11.3.

Here are the SDK components I am using for the project:

Does anyone know what could be causing this issue?

Thanks,

Ian

Thank you, I was able to get my project to build starting with the example.

Hi ishelly404，

  When you import the frdmk64f_sdcard_fatfs_freertos project directly, do you have the build issues or not?

If no issues, you can import this project, the you can use the project right click, copy and past, to rename the project to your own project name, and do the modification based on that project:

Please try it on your side.

If you still have questions about it, please kindly let me know.

Best Regards,

Kerry

@kerryzhou Great, but what if I want to add some component later-on and the conflicts pops up? Starting over from some sample that builds may not be a viable option.

There is apparently a naming conflict between 

../component/osa/fsl_os_abstraction_bm.c:86:31

    typedef task_control_block_t *task_handler_t;

and

../component/osa/fsl_os_abstraction_free_rtos.h:77:22:

    typedef TaskHandle_t task_handler_t;

The only sane solution is to fix the name conflict, by renaming one or the other type, and reissue the SDK.

Since the first declaration above seems to be local (inside a .c file) it may be best to rename this one as the name change won't spill.

A better name for a pointer to a task_control_block_t could be ptask_control_block_t, thus the typedef could become

    typedef task_control_block_t *ptask_control_block_t;

then all instances of task_handler_t in that file should be renamed to ptask_control_block_t.

Hi @axelrietschin 

  For your question, please create the new question post.

 Give your board, SDK version information, then we will help you. Don't follow the resolved post with new questions, thanks.
