Setting Up OTA DFU for BMD-350-EVAL Board Windows 10

[Caleb Dueck]

Hello,

I've been struggling to follow along with this tutorial:  Getting started with Nordic's Secure DFU bootloader, a step by step guide 

Is this the most up to date instructions for how to update the device over bluetooth?

I'm using SEGGER 5.68 and nRF 17.1.0

Thanks,
Caleb

Hi Caleb,

The nRF5 SDK bootloader has been more or less the same for a long time now, so the tutorial you linked to is still valid. I would suggest reading that for basic understanding, and then testing with the SDK bootloader examples and referring to the SDK bootloader documentation for details.

Also, I tried using Oberon but as mentioned in the tutorial I ran into memory issues.

Where can I adjust my flash starting point? I've tried to find documentation on this but cannot find it.

I would suggest sticking with micro-ecc if you want as small flash usage as possible, as you do not do that much crypto in the bootloader so size is probably more important than performance in that case, ans micro-ecc is the smallest. That said, flash adjustment is the same in the bootloader as with any other project. See Adjustment of RAM and Flash memory.
