thanks for your clarification, i will try in 7.80.4 version

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.

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 - When building the project, you might get the warning: "The header file 'cmsis_iar.h' is obsolete and should not be used.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>.

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?

i never made any changes by default it shows that error

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?

the project running with segger embedded studio but if i use with IAR it shows too many C++14 library error.can you help me

I have attached the project: devzone.nordicsemi.com/.../simple_5F00_coap_5F00_client-_2D00_-uart.zip

I noticed that the example initialize CLI with UART transport. This might be the reason why the UART_ENABLED=0 was set in the preprocessor definitions. I do not know how this example will react, as both CLI UART0 and app_uart on instance 1 is configured with the same pins. However, you should at least be able to test the example and use it as a reference.

Can you please send the code which you have run successfully for my reference..if I run simple_coap_client in iar it shows 100 more errors for c++ library and in segger embedded studio I can't find preprocessor symbol.

Did you modify anything else in your sdk_config.h after you uploaded it here? I was able to compile the project with added UART source files with your sdk_config.h file from this post, after removing UART_ENABLED=0 from preprocessor defines.

RE: Unknown type name error in nrf_drv_uart.h

Now i have these 6 errors

nrf_drv_uart.c
unknown type name 'nrf_uarte_baudrate_t'
unknown type name 'nrf_uarte_error_mask_t'
unknown type name 'nrf_uarte_hwfc_t'
unknown type name 'nrf_uarte_parity_t'
unknown type name 'nrf_uarte_task_t'
unknown type name 'nrf_uarte_event_t'

can you please tell me how to remove preprocessor symbol in Segger Embedded Studio

Jørgen Holmefjord — Wed, 12 Jun 2019 15:18:13 GMT

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

devzone.nordicsemi.com/.../2553.sdk_5F00_config.h

I have uploaded my sdk_config.h for your review, still i have same problem.Is it possible to use UART0?

RE: Unknown type name error in nrf_drv_uart.h

Jørgen Holmefjord — Tue, 11 Jun 2019 14:10:19 GMT

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
