I am using TM4C1230C3PMI controller from Texas instrument in one of my project. It has 32KB of internal flash, which is not sufficient for my application. Higher flash sized micro-controller are available in the market which can be used but I want to go with this micro-controller only. As per my knowledge external EEPROM can be used to increase the total flash size (Program memory).
Is my thinking is correct?
If not please suggest how can I increase the total flash memory size of the controller?

You cannot extend the program memory (flash). TI produces the same chip with double the flash and RAM, but nothing else changed: TM4C1230D5PMI.
If you cannot use a chip with larger flash, you will have to reduce your code size:
printf
function. Aprintf
that supports floating point output will typically set you back around 5KB-10KB.-Os
.-flto
. You have to pass-flto
to both compilation and link stages, for all files. This typically reduces the produced code size by 30%-50%.
