How to configure GPIOs for different domains (FSBL and Application)?

[matt-crc]

Hello,

I'm using the STM32N657 on a new project, and its not clear how users are supposed to setup GPIOs that are used in different domains (FSBL, Application, ExtMemLoader).  For example I am using pin PN12 as a LED output and defined it in FSBL.  Why doesn't this definition carry over to the other domains, and how can I get CubeMX to carry it over to the other domains?

thanks

Matthew

Hello @matt-crc 

It should be possible to assign the same GPIO in multiple contexts, in the same way as on the STM32H7R.

A Ticket 224701 has already been escalated to dev team to correct this behavior. 

In the meantime, you need to add the GPIO configuration code manually if you want to use it in different contexts.

I will keep you posted with updates.
