Cannot write SCI registers with lab01 on F28069M ControlCARD

Other Parts Discussed in Thread: MOTORWARE

I am working with an F28069M ControlCARD.

When I load a legacy project, I can modify the SCI registers via code or via the debugger.

However, when I load MW proj_lab01, my code does not modify the SCI registers, nor can I modify the registers from the debugger.

This condition is true when I break on the first line of main, so the difference must be in the linker command file or the boot code.

What am I missing?

    Hello,

    Which legacy project that you used?

    As I know, proj_lab01 is used to blink the led, no SCI implemented in this project. Do you modify this project to have SCI implemented ?

    Best regards,

    Maria

    The legacy project was derived from an old version of MotorWare.

    I included the proper sci.c and sci.h files and it compiles and runs. The weird thing is that I cannot modify the registers from the Registers tab of the debugger.

    When I change the build settings of proj_lab01 to the same build settings as the legacy project, I get several of the following linker errors:

    error #16008-D: file

    "c:/ti/ccsv6/tools/compiler/c2000_6.2.7/lib/rts2800_fpu32.lib<fd_neg.obj>"
    specifies ISA revision "C28FPU32", which is not compatible with ISA revision
    "C2700" specified in a previous file or on the command line

    don't change the build settings.

    the compiler build is set-up correctly in MotorWare.

    I think you just need to go through the process of enabling the proper clocks, PIE, GPIO set-up etc. 

    by default not every peripheral is ON and ready to use in a project.  In the project all we are activating is what is required for the specific EVM we are using, nothing else.
