Does Single-slot DFU with MCUboot support nRF52 series?

[keithauhk]

I just realized this feature is available from NCS V3.3.0.

Does it support nRF52 series such as nRF52832 with DFU through BLE?

In this page, it seems only nRF54 are included:

Thank you!

Hello,

No, this is not supported in the current SDKs. For that, you would either need to use the nRF54L-series, in combination with the NCS Bare Metal (scroll a bit down on that page to see the Bare Metal option).

Or you would need to use the nRF5 SDK, which has it's own legacy, bare metal bootloader.

Best regards,

Edvin

Hello,

Sorry, I was mistaken in my previous reply. This feature is available in NCS, although only officially supported for the nRF54 series. However, technically, there is no reason why it won't work for the nRF52-series (as long as there is enough flash). You can try to build it for the nRF52832, and see if you can fit your application next to the bootloader and FW loader. 

Best regards,

Edvin
