Reading file nrf_fprintf(line) ?

Dear Members,

We tried reading file with nrf_fprintf()....

Code :

 NRF_LOG_RAW_INFO("Entries count _sd: %u\r\n", entries_count);
	  //printf("UART text \r\n");
		NRF_LOG_INFO("Reading file \r \n");
		f_open(&fil, "HRM.TXT", FA_READ);
									
								/* Read all lines and display it */
								while (f_gets(line, sizeof line, &fil))
							  
								 nrf_fprintf(line);
								 
										/* Close the file */
						
								NRF_LOG_INFO("Finished reading file.. \n \r\n");

								f_close(&fil);
}

Output in UART :

Does anyone know on how to rectify it ?

Hello,

Please check which ASSERT is triggered at line 67 in nrf_fprintf.c in your SDK version.

Hi Vidar,

Thanks for the reply,

We can see :

Line 67 is

ASSERT(p_ctx->fwrite != NULL);

SDK =

D:\nRF5_SDK_17.0.2_d674dde\external\fprintf\nrf_fprintf.c,

What do we miss here ?

We want to display all the content of text file to UART.

I'm not sure how you were able to build the code in the first place as you are only passing 1 argument to your nrf_fprintf() call. I checked the function declaration, and it seems to require at least 2:

You can use the NRF_LOG_RAW_INFO() macro if you want to print strings without the logger prefix.

Hi Vidar,

Thanks for the reply,

We tried :

f_open(&fil, "HRM.TXT", FA_READ);
                               uint32_t bytes_written;
                               /* Read all lines and display it */
                               while (f_gets( line, sizeof line,   &fil))
                                NRF_LOG_INFO("data: %s",line);
                                       /* Close the file */

                               NRF_LOG_INFO("Finished reading file.. \n \r\n");

                               f_close(&fil);
