Smallest Possible WiFi Firmware?

Postby vonnieda » Tue Dec 12, 2017 4:21 pm

Hi all,

In an effort to create a recovery partition for my product I would like to determine what the smallest possible firmware image is that has WiFi support. I've created a very simple "hello_wifi.c" that simply brings up WiFi and connects. The resulting image is about 416kbytes. I'm wondering if there are any tips anyone can share to make this even smaller?

I've attached the code and the sdkconfig I'm using. In menuconfig I've disabled everything I can before the build process breaks.

Thanks,
Jason
