When I trace the code in debugger, I get <optimized out> for some variables

[RaNo_3455531]

I am trying to view the content of a variable in WICED SDK in debug mode

I reduced the compiler optimization to -O0 in the file: wiced_toolchain_ARM_GNU.mk file (located under \tools\makefiles)

Here is a snapshot of the screen during the debugging session:

I really appreciate any help.

Thanks,

Ramzi

Optimized out means that the variable is kept in a register so that the debugger cannot access it. When you have the choice you may set the compiler optimization level to "none".

You can try using the volatile qualifier with the variable. For example, volatile size_t fill. That might help.
