External Flash of STM32L4 Through Boot Option

[Rogers.Gary]

Hello:

I wish to understand how to set up the hardware on an STM32L476Rxx device so I can flash the controller through a serial port. Is there documentation to support this, such as an app note? (unable to find anything) Any help is appreciated. Thanks.

Hi,

Another search found the app note "AN2606", which I will read first. Thanks!

AN3155 is also recommended https://www.st.com/content/ccc/resource/technical/document/application_note/51/5f/03/1e/bd/9b/45/be/CD00264342.pdf/files/CD00264342.pdf/jcr:content/translations/en.CD00264342.pdf

There should be some open source examples, and also the Flash Loader Demonstrator
