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

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

Need to configure the CMSIS-DSP library as shown here: www.iar.com/.../
