TMS320F28379D: Data access count on CCS10

Part Number: TMS320F28379D

Hello, I'm using CCS 10.2.0 on a TMS320F28379D. The JTAG emulator is an XDS200, if that matters.

What are the possible reasons why the "Data Access Count" HW breakpoint does not work? The counter remains always zero.

Setting an hardware watchpoint on the same location, it works fine.

Thank you!

Hi Larry,

I was able to get "Data Access Count" to work. I assigned a variable to the Data Access Count and at the end of execution when I halted the CPU, the count matched expected value.

How are you setting up the address in the Data Access Count? Here is some documentation:

Thanks,

Hello Ashwini, I previously did not notice the part "Halt the code when desired". I believed that the data access counter would increase in real-time during the execution, but you actually need to interrupt the execution to update it. Fortunately a code suspend (Alt-F8) is enough, you don't need to halt the execution all the way.

Thank you!
