printf is creating error while building the SPI example in 11.0.0 sdk

spi.rar

Hi,

As a beginner, I want to combine spi and uart example in nrf52 11.0.0 sdk, for my application. I have included all libraries and driver files from uart in spi sample code. But while building the example I am getting following errors:

Error[Li005]: no definition for "__lseek" [referenced from xfspos.o(dl7M_tlf.a)] 
Error[Li005]: no definition for "__close" [referenced from fclose.o(dl7M_tlf.a)] 
Error[Li005]: no definition for "remove" [referenced from fclose.o(dl7M_tlf.a)] 

Why these errors are coming ? Does anyone has any idea about this?

Hi,

Make sure that you have latest version of the nRF5x-MDK-IAR (8.11.1), you can download it here.

Also make sure to select the correct processor core in the project options: Project->General Options-> Target -> Core: Cortex-M4F

Hi Sigurd,

I have installed the latest version of of nrf MDK . in project Option :Project->General Options-> Target - I am using nRF52832_xxAA device. Still the error is appearing.

In new SDK 12.0.0 I am using fatfs example. In this example, to print the data over terminal, NRF_LOG_INFO() is used. Now for getting character from terminal I am using getchar() function.

So, Here I am getting similar following error,

Error[Li005]: no definition for "__read" [referenced from xfrprep.o(dl7M_tlf.a)]

Do you have any idea about this?

What IAR version are you using? I'm not able to reproduce the errors in the SPI project you uploaded, using IAR version 7.3

Hi Sigurd, I am using IAR 7.4 for developing the projects.
