Error to use variables and structures into nrf_log_internal.h file

[Renato Silva]

I am trying add the fatfs example in my custom solution and I have the follow error after add the paths and files.

nrf_log_frontend.c:92:35: error: unknown type name 'nrf_log_module_dynamic_data_t'

I am trying use variables and strutuctures that are in nrf_log_internal.h but the Segger tell me that the types and variables declared in this file doenst exists. I dont know if I forgot to set any flag into sdk_config.h

Ps. I already added the path to the file where is declared the "nrf_log_module_dynamic_data_t" variable.

I assume you have added the header files the right way (Project -> Options for Target ... -> C/C++ in Keil or Project-> Edit Options->Preprocessor->User Include Dir.. in Segger).

I was able to add the FATFs example into the template_project provided by the sdk, but I wasn't able to recreate the error you got. I couldn't figure out how the sdk_config.h file would cause this either. Could you attach your sdk_config file?

Hi Simon,

I added the path to header path the right way, I resolved the first problems this way.

In my project I created a folder and added all files associed. Furthermore, I created a file called sdc_write and in this, I put the fatfs_example function. I created also a header file that contains all dependences and variables declared.

In my main file, I added the #include "sdc_write.h" and called the fatfs_example function

After these stepes I resolved the problems about references (paths and C files).

Now I have the follow output:

And still the segger show that balloc (nrf_balloc.c:46) is undeclared.

I am attaching the sdk_config file.

0447.sdk_config.h

[Simon]

It is difficult to figure out what causes the error when not having the code, but I have attached the code where I integrated the FATFs example into the template project, and you can further build your solution upon that.

template_project.7z

Hi Simon,

I tryed to insert the fatfs example into blink example (SDK 14.2) and it works!

Now, I am to insert the fatfs examplo into light switch (SDK Mesh) and I have the same problem.

In nrf_drv_spi file the segger show that (#define NRF_LOG_MODULE_NAME spi) the spi variable is undeclared.

Is there any particularity in the SDK that prevent I insert the fatfs example?

[Simon]

I got the same error, but solved the problem by setting SPI0_ENABLED to 1.

Best regards, Simon
