Hello everyone,


I am trying to work on getting the SPI communication going with the FRDM-K22F ev board, but when I compile my code, I get the following errors:

C:\Freescale\workspaces\KSDK_guide\Debug/../Sources/main.c:128: undefined reference to `SPI_DRV_MasterInit' C:\Freescale\workspaces\KSDK_guide\Debug/../Sources/main.c:129: undefined reference to `SPI_DRV_MasterConfigureBus' C:\Freescale\workspaces\KSDK_guide\Debug/../Sources/main.c:132: undefined reference to `SPI_DRV_MasterTransferBlocking' C:\Freescale\workspaces\KSDK_guide\Debug/../Sources/main.c:137: undefined reference to `SPI_DRV_MasterDeinit'


In addition, I also get the following warnings:

I get a bunch of similar warnings from above, all related to the fsl_spi_hal.h ; Below is my code snipped:

#include "fsl_device_registers.h" #include "board.h" #include <stdio.h>
#include "fsl_spi_hal.h" #include "fsl_spi_master_driver.h" #include "fsl_i2c_master_driver.h"  void func(){ //init the spi module     SPI_DRV_MasterInit(SPI_instance,&mstate);     SPI_DRV_MasterConfigureBus(SPI_instance,  &userConfig,  &calculatedBaudRate);       //configure the spi bus      statRet = SPI_DRV_MasterTransferBlocking(SPI_instance,                                           NULL,                                           sendBuff,receiveBuff,                                           numBytes, timeOut);       SPI_DRV_MasterDeinit(SPI_instance); }


I read somewhere else that this is possible due to a linker/path error. But the weird thing is that if I try I2C it works fine and does not complain at all. And since I2C and SPI are in the same path (drivers/inc), I see no reason why SPI won't work, but I2C does. Here are 2 images, 1 for the build includes paths, and 1 for the includes tree



It just drives me nuts that the UART, and I2C work fine, but the SPI will not! Any help will be extremely appreciated.


Note: I build the project from scratch utilizing this guide called "Writing my first KSDK Application in KDS - Hello World and Toggle LED with GPIO Interrupt.PDF" that I found floating around in another thread. It also does not work if I import the Demo "Hello World" project. Same error.
