Tool/software: Code Composer Studio
my customer use the CCS3.3 to develop their Tms320F28335 SW, they used the Opt level to optimize their code,but found a strange problem.
they use the Register o0 to optimize the code, when they dowmload the .out file to the dsp, they found that the code running abnormal.
while they use the o1,o2,o3 to optimoze the code,the code running normal.
so my question is :
1: what is the function of the different optimize level? when we want do the code optimize, how we choose the level?
2: In my opinion, the high level optimize contains the low level optimize,so why is there such a problem.
