Firmware download under MCUboot

[joey]

HI

Currently using NRF54L15 with NCS v3.0.0 and the periodic_sync_conn sample. I have created sysbuild.conf and added SB_CONFIG_BOOTLOADER_MCUBOOT=y. After compilation, MCUboot logs are successfully generated. I want the broadcasting device to include firmware update content in its advertising data, and have the synchronized node receive this data and save it.

Questions:
What API should the synchronized node call to save the received update data? After completing the save process, how can it reboot into MCUboot to achieve seamless integration with the MCUboot application?

Thanks!

Hi!

Can you explain a bit more what you mean by this? advertise FW update content?

Incorporate the upgrade firmware for the synchronous nodes into the synchronized broadcast from the central node. After receiving the synchronized content, the synchronous nodes will store the upgrade data in flash memory.

We don't have support for that. You will need to connect and do a regular transfer over BLE GATT
