TMS320F28374D: CLA : hanging related to code lines when having 3 tasks

Part Number: TMS320F28374D
Other Parts Discussed in Thread: C2000WARE

HI everybody , 

I m using CLA   and have 3 tasks  : everything is OK   but then I added  code  (  just few lines  ) and  CLA hangs .

I added  code in Task 3  , and have the issue . So I removed  and put extra line in Task1  and  got same crash : so it seems related to code size .

questions :

- do you have a working example  with more than 1 task   I can cross check vs mine ? 

- what can I check  to find this issue ?   

- do you have a proper  linker file  I can use to be usre issue is not there ?

bets regards

Carlo

    Hi Carlo,

    We have few examples that has multiple CLA tasks configured.For example : cla_vminfloat example under device_support folder.

    <C2000Ware>\device_support\f2837xd\examples\cpu1\cla_vminfloat

    For debugging the CLA code, you can add __mdebugstop() to insert breakpoints on the CLA code. In debug mode the CLA execution will halt when it reaching the mdegugstop function. If debugger is not connected it acts as a NOP instruction.

    You can use the linker command files used in the CLA example available in the C2000ware.

    Can you also send us the sample project which we can run to reproduce the issue on controlCARD ?
