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

Colombo Carlo

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

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.

Hi Carlo,

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