Simultaneous multi-image DFU RAM question

[tomas_mjp]

Hello, acording to the Simultaneous multi-image DFU documentation a RAM section is needed to act as a flash simulator during the network core update.

Is this RAM section only allocated by MCUboot during the upgrade procedure or is it statically allocated during normal operation of the application core?

I want to know if this ram_flash section is consuming resources of my application.

Regards

Hello,

The RAM flash region is only allocated for the MCUBoot applcation and does not impact RAM usage in the main application. The CONFIG_NRF53_UPGRADE_NETWORK_CORE symbol can be used to enable this partition in the bootloader.

Best regards,

Vidar
