I've followed the instructions here to try and get my J-Link debugger to run in bootloader.
I am using a newer SDK and SD (than the post was written for) so that may have something to do with why I can't get the debugger to run.
I'm using: Custom PCB with nRF51422 (256K ROM) chip SDK 9.0 SD 310 version 3.0
For the bootloader I started with the dfu_dual_bank_ble_s310_pca10028 example, and added the DFU support to my custom application.
I can successfully do OTA BLE updates. I want to be able to step through the bootloader code to get a better understanding of how it works, and make a few minor changes to customize it to my application. I can not do this until I can get my debugger working.
Are there updated instructions on how to debug the bootloader, or can someone guide me through the changes from the above example to get the bootloader running?
Thanks, Clint
