Welcome, @Karthik Kumar, to the community!

The file size of the HEX file is irrelevant, since it is a text file with additionally addresses, checksums, etc. Comparable with the Flash size would be only the BIN format.

So, don't worry, a HEX with 45KB perfectly fits into a 32KB Flash.

Hello @Peter BENSCH

I couldn't locate the hex file in my project folder. I can see the .elf file and .BIN file. Could you please help. I am using stm32f429zi on a Nucleo 144 board.
