Other Parts Discussed in Thread: SYSBIOS,
Tool/software: Code Composer Studio
I've installed:
-
Code Composer Studio v6.2.0.00050
-
Processor SDK v 03.01.00.06 for RTOS
And I have trouble using CCS to start a basic (typical) ARM project and build it for my platform, the TCIEVMK2X evaluation module (uses the TCI6636K2H processor). These are the steps I followed:
- Right click on the "Project Explorer" tab and select "New->CCS Project"
- On the second window, selected the project template from "SYS/BIOS -> GNU Target Examples -> Typical".
- On the 3rd window, selected the platform "ti.platforms.evmTCI6636K2H", and click on "Finish".
- Clicked on the "Build Hammer" button to build the project.
The screenshots for these steps are below:
When I built, I got the following error:

I don't understand why a template configuration would result in this error. The main.c file has no floating point operations, but the linker flags seem to want to link to a "fpu" directory, yet it still searches for a libgcc.a in a different directory. I did notice that there is NO libgcc.a file in the fpu directory it tried to link to:
~/ti/bios_6_45_01_29/packages/gnu/targets/arm/libs/install-native/arm-none-eabi/lib/fpu$ ls crt0.o libgloss-linux.a librdpmon.a rdimon-crt0.o redboot-crt0.o iq80310.specs libm.a linux-crt0.o rdimon.specs redboot.ld libc.a libnosys.a linux.specs rdpmon-crt0.o redboot.specs libg.a librdimon.a pid.specs rdpmon.specs redboot-syscalls.o
Is there a misconfiguration in my environment somewhere, maybe due to an incompatibility between Processor SDK and CCS?
