CCS: how to turn off dsp code optimization ?

Tool/software: Code Composer Studio

Hello,

When i set the optimization level to -Ooff , it occures error: argument to option -O (0-3) is out of range (must be a number from 0 to 3).

So how to set it to -Ooff to turn of the dsp code optimization ?

Thanks!

Hello!

It seems to be compiler specific question, but probably you may try to not specify -O option at all.

Thank you!
But i need to set all the code -O3 in a header file , and then set some part of code to -Ooff , the compiler has -Ooff selected exactly, right ?

Hello,

take your compiler manual and check what -O0 means.
Using file properties, you can set an optimization level for each source file separately.

Gao - which compiler and device are you working with? The options vary depending on the compiler version and family.

Thanks
