Hello,
After making some research, I learnt that i can run C54x code on C55xx simulator. Simply, I would like to run FIR filter code on C5416 device. According to instruction that i got, I first tried C5509 code and run it which is seen on code window 1.

After I converted the above code to implement into c5416. Even though I built up successfully, I cannot get any output y0, y1 and y2 result according to below code. I saw an instruction that I need to use accumulator A by writing AB and already set BSET C54CM. I cannot figure out where the mistake is.

Additionally, I am using ccs v5.5 and for the linker command file for C5509 and C5416 are shown below. As I said, as C5509 works, C5416 is not working.
