NRF_LOG() / CLI problem - NRF_CLI_CMD_BUFF_SIZE is undefined

[Den]

Hi All,

I am working on  ISP1507 which is based on NRF52832. My IDE is Keil V5.26.2.0.  I have had the following problem in the UART example (pca10040e) from SDK 15.0.0. I am fairly new working with all these. 

I was trying to amend the UART example according to my needs. However at some point, the application started to reset continuously due an error that I could not have defined. After some research I have found that I have to check the error log written to SEGGER RTT by NRF_LOG (please correct me if I am wrong). I have then tried to get the NRF_LOG working according to the instructions I have found here. However I have stuck.

I have included the necessary ".h" files and their paths. I have also added the ".c" files under "nRF_Libraries" (under "Groups" in "Manage Project Items"). The files I have added, includes some other files which were not initially found by the compiler however, I have gradually added every single missing file. However in the last file I have added, nfc_cli.h, there is a missing MACRO, NRF_CLI_CMD_BUFF_SIZE, and I could not have overcome this one. Where is it defined? What else should I include?

Thanks,

D

Define NRF_CLI_CMD_BUFF_SIZE shall be defined in sdk_config.h file. Please check CLI example:

nrf5\examples\peripheral\cli

Hi again,

I have added it manually. That one solved. Then I had to add NRF_CLI_PRINTF_BUFF_SIZE too, which I have. Now I am having something bigger. Please see below. 

Is this how I should get NRF_LOG working for the uart example or am I missing something fundamental?

Thanks,

D

What I require is particularly UART. I am trying to adapt it for my application. I need NRF_LOG() to figure out the error I am suffering from. Thanks for your help anyways. 

[Jakub Rzeszutko]

To be homest I am confused now, why do you need CLI? Please let me know what do you excactly would like to have in your application?

My current understanding is that you need UART only for logging purposes. In this case you do not need CLI.

Or maybe I am wrong and you need UART for logging and communication with other devices?

[Den]

Sorry if I have not been clear enough. I am developing an application by which NRF52832 will communicated with another MCU via UART. This is the primary use.

While adapting the the UART example to my needs, I have had an error. The application started to enter "__WEAK void app_error_fault_handler" . I was trying to figure out the reason for this.

After some research, I found that I should check the NRF_LOG() output on the RTT. This is why I am trying to get NRF_LRG() working. And while I am trying to do so, I have added NRF_LOG() files and done the necessary changes in sdk_config.h. However, the files I have added included some other files. I found and added these missing files too. This has led me to CLI files...

[Jakub Rzeszutko]

 I can share with you UART example configured to use RTT logging.

Please let me know what DK do you use?

[Den]

Thank you very much. I will have a look at your example and see what I am missing. I have to figure out what is going on with this even if it is solved with you example.

I am using ISP1507 module development board, it has the same settings with PCA10040. 

[Jakub Rzeszutko]

Please find attached configured projects (SDK15.2) for SES and GCC. Just replace folder uart in sdk examples with attached one.

8015.uart.7z

[Den]

I guess this project file is for SEGGER Embedded Studio. Is there a way to open it with Keil uVision?

[Jakub Rzeszutko]

Please find attached Keil project as well.1464.uart.7z

[Den]

Thank you very much Jakub. I will go through your project to see what I am doing wrong and share it. 

Regards

D

Thank you very much for all your efforts. However, unfortunately I have not been able get it work. I open the uart_pca10040.uvprojx and try to compile it, I get 29 errors, it cannot find some of the files. I check the Folder Setup to make sure of the paths. I have confirmed a number of them, I have even reselected some of them but I still get error for them. 

Please see the project section in the left. I think there is problem with arm_startup_nr52.s and system_nrf32.c  under Device. 

Am I missing a setting or something?
