How to port the SDK 8.1.0/ SDK 8.0 boot loader to custom board

[Anshul]

I want to implement the OTA update in nRF51822 on my custom board. I am using the bootloader example in the dfu folder for this. When I try this code on the DK, it works fine but when I use the same code on my custom device, the device does not even advertise "DfuTarg". The only change I made is that I re-mapped the Button and LED pin configuration as per my board.

It would be really helpful if someone can give an idea on what else must be done in order to get the bootloader code to work.

Hi, could you provide some information about your layout? Ideally post the entire layout. Are you using external oscillators?

[Anshul]

Yes, I am using external oscillator for both the clocks.

Hi,

You need to tell Keil which board you are using, for more information see the tutorial on the Board Support Package, specifically the section on Adding Support for a custom board

Here's an answer to a previous post on debugging the bootloader that shows how to set up debugging, in case this does not fix your problem.

You also need to make sure that you have configured your oscillators correctly.

Best regards,
