A 12kB 'Compact' External Loader

ST documentation and examples brings to ELs needing more than 40kB of RAM in the STM32.
Here I show a version of my library allowing to generate ELs needing 12kB or even less.
As this is library doesn't follow all the ST indication, I published it in a separate repository.
Now you can choose between the "standard" ELs and the "unorthodox" ones.

00:00 The limits of the "standard" ELs
03:45 The role of Linker
07:42 Changing the linker script
11:09 The Verify() function
12:48 The Read() function
17:14 Read() & Verify()
19:59 The Checksum() function

All information are listed in description and exposed in the other videos of this series about External Loaders for SPI flash memories. I strongly suggest you to see them before accesssing this video.

I found your channel by accident, great video. Everything was explained simply, the code is quite clear, thank you.

These days I'm interested in TouchGFX and external flash. A very useful and educational video. A necessary video for cheap stm32 versions. Thanks.

Hello Mauro!! Thank you so much for doing this for low ram MCUs, i'm going to try this on my G0 projects 😀

Thanks for the video. Great work. The repo is currently private.
