The link I gave on the first comment, shows the order of programming,
Upgrading to 2.0.0
You must re-program three (3) different microcontrollers: Chipkit Pic32 (hereafter called Pic) on the Board, RFduino on the Board (hereafter called Device), and the RFdunio on the Dongle (hereafter called Host).
The order of programming should go as follows
Flash the Device with RadioDevice32bit
Flash the Host with RadioHost32bit
Flash the Pic with DefaultBoard
This will get you to v3 PIC firmware. Even though the section title says v2. Because the DefaultBoard you are using is already v3. You must flash in the exact order given.
Hi, in the instruction to program, there is a mention of blue-button on board:
Cyton board version we have is: V3-32, is the capacitor already present on board?

Thanks for replying,
The links mentioned in the guide has expired / or moved.

After following the above links, I am getting redirected to below website:

Docs have moved to their new locations. Did you try looking?

Yes,
Which procedure to follow for freshly fabricated Boards, cyton & dongle? Should we follow cyton radios guide?
Or, first cyton radios then cyton program?
Also, after following the steps in cyton radios programming guide, no RFDuino board found under tools > board:

Please guide, as there is no clear instruction.

Hi William,
We tried flashing the RadioDevice32bit to the board, that is DEVICE. We got an error message saying the following:

Appreciate your help on this.
Did you use the "Google Advanced Search" button in the upper left column?

Hi @William,
Thanks a lot for your help, I could flash the device and host successfully.
Regarding programming Chip (Pic32), do we need to follow Cyton programming tutorial?
Thanks & Regards,
Pluto
