Sharing UART between SBSFU and user app

Hello

I would like to use the same UART that is used in SBSFU, to communicate with the host PC for service purposes. Is it possible? Maybe create kind of a wrapper interface like "press 1 for sbsfu, 2 for logs"? A little bit confused how to implement it if possible. It is the only UART available on my custom board, all pins are already used.

Hello @leeana​ 

there no problem sharing the link between SBSFU and application. As soon as SBSFU jumps to application you have access to all resources.

Best regards

thank you, Jocelyn! After re-reading the docs for a fourth time I've finally got how it works.
