Cannot jump from Bootloader to Application with custom board

Ok. Just wanted to check. The SDK examples are set up to use an external LFXTAL, but it is optional. Just wanted to check if that may be the issue.

Can you try the debug version of the bootloader and monitor the log? What does it say?

BR,

Edvin

I have tested the application standalone, it works well.

Please make clear about the role of LFXTAL, I have a part of the schematic, see an image below

Thanks for your help

Hello,

Have you tested the application without the bootloader on your custom PCB? Does it run as expected?

Can you try the debug bootloader project foun in:

SDK_X.Y.Z\examples\dfu\secure_bootloader\pca10040_ble_debug

And monitor the logging on your custom PCB?

What would you say are the main differences on the custom PCB and the DK? Do you have an external LFXTAL?

Best regards,

Edvin
