https://devzone.nordicsemi.com/f/nordic-q-a/6294/why-is-my-dfu-update-crashingHello, I tried to get the bootloader dfu example with the S110 8.0 and the latest 8.0.0 SDK running but ran into tons of issues. The packet handling with KEIL is just insane so I ended up copying the files and writing the includes myself.

If you don&#39;t like the packet handling in Keil, I&#39;ll suggest you just use the zipped SDK version instead (nRF51_SDK_8.0.0_5fc2c3a.zip). You can find it here: <a href="http://developer.nordicsemi.com/nRF51_SDK/nRF51_SDK_v8.x.x/">developer.nordicsemi.com/.../</a>. This does not use packs.</p><div style="clear:both;"></div>
