1.flash in ccs debug image
2. ccs start and launch a configuration using awr2x44p
3.build a debug version and find a variable you may want to monitor like this:
here the forth (index 3) in gMmw_MCB.cqSigImgMonCfg with profileIndex initial value 0 and address at 0x10253860
4.Find the hardware breakpoint in the left bar in breakpoints:
5.add hardware watch point like this. Input the location of the variable you want to see and set the access type as "write" if you want to break when the value of the variable is changed. You can change to read if you want to halt whenever this value is read and change to any if you want to debug whenever read or write.
Change to any if you are afraid of losing track
6.After setting the hardware watch point, continue the program and it will halt the cpu where this address is accessed:
7.To analyze this further, you can check the disassembly here and you can see this command:
strb r3, [r1, r0]
Meanwhile, you can check the registers.
r3 is 5, which is the data to be assigned.
r1 is 0x1025386c and r0 is 0xfffffff4 (-c).
So this is to put number 5 into 0x1025386c - c.
