Application not running on a Rigado BMD-300

[drumm3r]

Hi all

Being fairly new to the nRF ecosystem I'm trying to get some basic code up and running on a custom board which uses a Rigado BMD-300. I'm using one of the examples in the SDK, and this runs fine on the Development Kit I have (PCA10040) but not on the BMD-300. I have updated the configuration of the clock sources as per this post (https://rigado.zendesk.com/hc/en-us/articles/225674668-Example-files-will-not-run-on-my-hardware-but-do-on-the-Eval-board-) 

However although the device programs and verifies fine (from both Segger Embedded Studio and nRFgo Studio) I see absolutely nothing - no flashing LEDs and nothing being advertised. Power seems fine, but I don't see a peep from the custom board.

I'm a bit stumped - what should I try next!

Thanks!

Use the debugger to see if the code is getting stuck or crashing somewhere ...

[drumm3r]

Ok, very good point! It seems that although the debugger throws no errors at all (seems to program fine then run) it isn't actually running the code. I can't step through the code, and it doesn't hit any breakpoints at all.

It is weird how I see no errors though!

AFAIK, there are not separate SoftDevices for working with and without an external crystal - it's just a matter of configuration ?

[drumm3r]

I see. In that case could you point me towards this configuration? I've been searching the forums and although I've found references to the changes needed they all assume you know where to look to actually make these changes!

[awneil]

Sorry - I've always worked with a crystal!

[drumm3r]

No problem - all this digging around at least means I'm getting more familiar with the setup! Thanks again for all your help

The sdk_config file configures which clock source that is used by the project. You can configure it to use the RC by setting it to 0: 

// <e> NRFX_CLOCK_ENABLED - nrfx_clock - CLOCK peripheral driver
//==========================================================
#ifndef NRFX_CLOCK_ENABLED
#define NRFX_CLOCK_ENABLED 0
#endif
// <o> NRFX_CLOCK_CONFIG_LF_SRC  - LF Clock Source
 
// <0=> RC 
// <1=> XTAL 
// <2=> Synth 
// <131073=> External Low Swing 
// <196609=> External Full Swing

I can't believe I missed this. Thank you very much!
