DFU Support for nRF52811

[Usman Rahim]

Hi, 

We are using nRF52811 for one of our upcoming product. We plan to upgrade our firmware via DFU. I cant find any support or example codes for this controller for DFU, so

1. Is it possible to have DFU support for nRF52811?

2. If its possible, is there any recommended memory map for nRF52811?

3. In the bootlooder code, how will i change the memory mapping?

Thankyou for your time.

If you application is small, it might be possible using the S113 Softdevice. Otherwise you would run out of flash memory.

Can you define Small? How would i do memory mapping for nRF52811?

Read the bootloader chapter in the NRF SDK documentation (infocenter).

Softdevice flash and RAM requirements are in the release notes for the corresponding softdevice, and AFAIK always part of the softdevice downloaded zip.

It is a good idea to compile some bootloaders and example application from the NRF SDK so you can get a feeling how much flash memory app and bootloader need.
