Tool/software: Code Composer Studio
Previously, we wrote a number of DSS javascripts to automate testing which ran without any problems under CCSv5, we have since upgraded our CCS to v9.2.0.00013 and the scripts no longer work as before.
We set the debug session up in the standard way, set 3 hardware breakpoints, then run through the system boot up sequence to check the boot sequence is correct.
The problem we are seeing is that the breakpoint code only works when we step through the code with the Rhino Debugger. If the file is run directly using dss.bat or is loaded into the Rhino Debugger, and just 'go' is selected, the code fails at line
if (nPC != BOOT_SOMA)
Giving the message 'FAIL: Expected halt at start of BOOT 0x40300000, actually halted at 0x8000000'. This would imply that after hitting the first breakpoint it restarted but the program counter didn't actually move before hitting the 2nd breakpoint!
I've attached an example of the javascript, could someone please explain why it now only works when we step through with the Rhino Debugger!!
