In a nutshell, if you never plan to update your product over the air and are prepared to always update your application and system firmware via USB, then you can build an application that is 384K in size. Note that this isn’t a supported configuration out of the box, you would need to take several steps to enable this. but it’s technically possible.
With that said, have you tried to compile these libraries? I’d also suggest that there are other platforms more suited to running heavier applications, such as the Raspberry Pi which would give you much more administrative control.
