Compiler error after importing FreeRTOS files

Posted by guggech on April 16, 2018
I am using the SAM4s Xplained board and I did successfully compile the Starter_kit demo1 and downloaded the application and verified the operation with the ATMEL studio 7.0 debugger. The board uses the ATSAM4sD32C chip with is the M4 family . I copied all the FReeRTOS files including the portc for CM4F and I am getting the errors shown below. Looking at the specification, it does say that this processor support the Thumb -2 instruction set and is an ARM CORTEX RISC processor. Any ideas? Thanks, charles

If your MCU does not have a floating point unit then you need to build the files from the ARM_CM3 directory rather than the CM4F directory – otherwise it looks like the compiler’s command line is not correct because the compiler does not think you have an FPU – update the command line to specify the FPU option that is correct for your particular part.
