Unknown type name error in nrf_drv_uart.h

[Sash]

I am using nRF5SDKforThreadandZigbeev300d310e7 sdk for thread example simple_coap_client. I try to add uart module with simple_coap_client and i have added uart configuration in sdk_config.h. While compile the program i get unknown type name error in nrf_drv_uart.h and i cannot find app_config.h to simple_coap_client folder. Can you please help me.

Error while build with SES:

Hi,

Please make sure that at least one of these are set in your sdk_config.h file:

#define UART_EASY_DMA_SUPPORT 1
#define UART_LEGACY_SUPPORT 1

Check the UART peripheral example for default config. If this does not help, please upload your sdk_config.h file for review.

Also, you should only include either app_uart_fifo.c or app_uart.c, not both (normally, the FIFO version is used).

Best regards,
Jørgen

Hi,

It seems that 'UART_ENABLED=0' is defined in the preprocessor symbols in the project. Removing this seems to fix the issue.

Best regards,
Jørgen

In general, we do not support C++ in the SDK, besides include guards. Are you using C++14 in your project, or did you make any modifications to the project settings?

[Sash]

i never made any changes by default it shows that error

[Jørgen Holmefjord]

Which version of IAR are you using? Do you have any specific settings in your IAR configuration that makes it compile any project in C++ mode?

[Sash]

i'm using 8.40 version for IAR. It is in default configuration in IAR i never changed so far.

[Jørgen Holmefjord]

I have not tested this version of IAR. In general, we recommend using the versions that the SDK is tested against:

The following toolchains/devices have been used for testing and verification:

 - ARM: MDK-ARM version 5.25
 - GCC: GCC ARM Embedded 7.2018q2.update
 - IAR: IAR Workbench 7.80.4
 - SES: SES 4.12
 
Note: The selected GCC version has shown instabilities when using the Link Time Optimization feature, and using the feature is not recommended.

*****
Note for IAR 8 users:
(Libraries for IAR 8 require wchar_t to be of size 32 bits while IAR 7 requires 16 bits).
 
To run a project using IAR 8, follow these intructions:
 - Open the IAR project in IAR 8. The IAR workbench will automatically generate an IAR 8 compatible project file.
 - If the project contains one of the precompiled libraries listed below, replace it with the IAR 8 compatible alternative
   (there are no projects targeting nRF51 in this SDK).
 - Save the project.
 - When building the project, you might get the warning: "The header file 'cmsis_iar.h' is obsolete and should not be used. [...]".
    - The problem is described in DevZone post: devzone.nordicsemi.com/.../iar-ewarm-8-22-1-complains-about-cmsis_iar-h
      The solution is to remove all occurrences of #include <cmsis_iar.h>.

I used this version also i faced same issue

[Jørgen Holmefjord]

I tested with IAR 8.22 and got the same errors you did. With IAR 7.80.4, everything compiles correctly. Please verify that you are using this exact version.

[Sash]

thanks for your clarification, i will try in 7.80.4 version
