CCS/TMS320F28379D: CLA code won't work without debugger

Daniel Ayala1

Part Number: TMS320F28379D

Tool/software: Code Composer Studio

I am developing firmware that uses the CLA to do atan2() and log() computations. When I have the debugger connected, the output of the CLA is correct but when I remove the debugger and run the same code. The output of the CLA is always 0. Like if the CLA is not doing anything.

Do you have any idea or suggestion on to where I should look to resolve this issue?

A couple of ideas, Daniel,

Could the Code Security be enabled when the debugger is disconnected, but unlocked when CCS is connected? This is user configurable so unless you program the security setting to secure them, these RAMs will be unsecure only and this won't apply. See these two related threads:

If you rule out code security blocking the access to LS RAM, go through this checklist - in particular making sure there are no initialized variables being loaded into RAM. CCS will do this for you, but stand alone this will not work.
