OTA with the BC480 eval board

[JAC]

Hi,

I have the BC480 eval board and I would like to be able to upload the simplist application to it OTA. blinky_pca10056.hex

I'm using the Nordic Toolbox application DFU.

It see the chip but give a DFU error when I try to upload.

I'm getting DFU file not found.

Any ideas on how I might get this to work?

Do I have to compile blinky in a certain way?

Many thanks,

John A.

Hi John,

The DFU process requires an init file with extra information about the update in addition to the application image.  The init file includes version requirements, the hash digest of binary image, type of upload, etc. which are not found in a intelhex file. I suggest that you go through Hung's guide here to get started:
