Hi,

Thank you for your prompt response.

I noticed that the SDK uses Os optimization in some places and Oz in other places. My question is which is it?

It will be dependent on example. But user is free to use any.

Some of the networking example size is a priority, for some example it may change, you can choose depending on your case.

CFLAGS_release := \
-Os \
-Oz \
-flto \

As mentioned below... it states that both Os and Oz are used?

Swapnil,

Please see below:

Please see that Oz and Os are not very different. Oz adds more size reduction on top of Os. Oz is taken priority over Os
