This page describes how to setup Hardware watchpoints in CCS 4 for the C28x CPU.

This feature was made available for C28x as of CCS V4.1.2. It was not available in earlier CCS 4 releases.

This short video clip shows how to set up C28x data watchpoints in CCSv5 which is similar to the process in CCSv4.

Make sure you have Code Composer Studio 4.1.2 or later. This feature was not implemented for C28x in prior releases of CCS V4.

Step 2: In the Debug Perspective, Open the breakpoint dialog: View->Breakpoints

Step 3: Use the pulldown to select a new breakpoint and choose Hardware Watchpoint


Step 4: Specify the address you want to watch, and if it is a read or write access.


Step 5: Right click on the watchpoint and select Properties.


Step 6: From this dialog box you can further configure the watchpoint:

  • Configure a data read/write of a particular value from the address.
  • Configure the size of the data
  • Configure a mask value (bits that will be ignored)
