Where could I find the sources of each external loader ? I have a Serial NOR Flash Memory MT25QL512ABB which is already implemented with different MCU's but not mine, I wanted to get the sources of an other MCU and to porte it to my MCU STM32H7B3xx.

ST has only selectively released examples, and they have a github for some which may or may not reflect those that ship

And I have binaries for ones I've built. I do have some built for H7 OCTOSPI platforms (ie H7Ax/Bx,H72x/3x), but I'd need to check the Winbond/Micron mixes I tested on the NUCLEO ZIF sockets.

Hi @Maël Lair​ 

You can start from G4 Board external loader located here, it's using same Flash.

Hope this helps you.
