Original question:

TMS320F28379D: Hardware Breakpoints vs. Software Breakpoints / CLA

TMS320F28379D: Does CLA of 28379D support the software breakpoint when I use the flash,

Part Number: TMS320F28379D
Other Parts Discussed in Thread: SYSCONFIG, C2000WARE

Tool/software:

Does 28379D support the software breakpoint in CLA when I use the flash, I try to add __MDEBUGSTOP() in THE CLA CODE. But when I try to connect the CLA in the debug, the system give me the error.:

CPU1_CLA1:Trouble Setting Breakpoint with the Action "Finish Auto Run"at ex8e95e:(Error -1209 ).

So I would like to know if the flash is used, the software breakpoint could not be implemented on CLA of 28379D.

    Hello,

    I'm assuming you are referring to running the c28x program code from flash? The CLA program must be run from a CLA accessible LSRAM memory (which on the F2837xD is all of the LSRAMs). When loading to flash, the CLA program needs to be copied over to LSRAM memory at runtime (from the c28x code). In the C2000ware CLA examples, the Sysconfig generated code shows how to copy the CLA program over:

    If your program already includes this, can you try looking at the map output file and make sure that the CLA program code is being placed in the correct area of memory?

    Best Regards,
