nrf51822 bootloader + mbed expert needed

[Shay Ohayon]

I am seriously stuck on a project. Expert help is needed. The goal is to create a modified dfu ble bootloader with the following properties:

1. Target: NRF51DK (nrf51822 QFAC)
2. Uses softdevice S130 v1.0.0
3. Single Bank
4. Has WatchDog (WDT) support
5. Accepts mbed os2 v0.4 updates (i.e. no zip file).

All my attempts to create such a thing have failed. It seems that mbed have introduced some specific modifications, but I was never able to compile their project (I believe this is the original code: github.com/.../nrf5x-dfu-bootloader).

I tried several things, including modifying the default examples from SDK 10, but the end result is always the same - the device gets stuck in bootloader mode and does not accept updates. Experts / Gurus / Mentors :) please come to the rescue!

Thank you,

Shay

Bump? Anyone here might have done something similar in the past?

Hi Shay, can this question be closed due to the development in this question or do you want to keep this open?
