STM32F429I-DISC1 FLASH overflowed, how should I fix it?

mchal.11 · ‎2022-01-19

Hello

since i encountered this problem

`ExtFlashSection' will not fit in region `FLASH'

`FLASH' overflow 6934684 bytes

I can think of 2 ways: 1. Reduce project size 2. Increase memory with Micro SD Card adapter.

I would like some advice on which method to use and how to do it.

(I am a beginner)

Welcome, @mchal.1, to the community!

If you are a beginner, you should simply reduce the project size. The STM32F429I-DISC1 has external RAM that can be used for the frame buffer, but only 2MB of Flash. You should not try to work with SD until you have gained some experience.

Good luck!
