How to update the MCUboot in nRF Connect on nRF52840DK

[RAS_ID]

Hi,

I press Button 1 and Reset to put the nRF52840 DK in to DFU mode that is programmed with a immutable bootloader (B0), mcuboot, and application. This works well to update the application (app_update.bin) using mcumgr over USB. However, during the mcuboot update (signed_by_mcuboot_and_b0_s1_image_update.bin), the application area is over-written and the application enters in a infinite loop after reset. I verified the over-write by reading the flash memory using the nRF programmer. 

Since mcumgr doesn't accept an address or slot parameter, I think the DFU mode is initialized with the application address. 

Are there different ways to enter the DFU mode to update the application and to update the mcuboot?

Thanks,

Ram

Hi,

 It's the Partition Manager that sets the start address in a multi-image build. See this link for more information: http://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.4.0/nrf/scripts/partition_manager/partition_manager.html

In your build folder, how does partitions_nrf52840dk_nrf52840.yml and pm_nrf52840dk_nrf52840.config look like ?
