Issue with configuration

[NJ_B]

Hii guys ,

      I am using custom board bluetooth module based on nrf52  which is CBTMN10. I believe I am able to dump example code on my custom board bluetooth module using NRF52 -SDK ,but I am not able to test it on mobile application of nrf Toolkit.

The followings are my queries,

1. How am I supposed to know whether the source code has been dumped on my custom device?

2. Do i need to do any modification on software side like configuring the crystal or something?

A1.You may use nrf connect - programmer  to make sure SD,MBR & APP code is exist or not. But if you want to apply the nRF toolchain. You have to make sure the BLE service is real follow the ble_peripera examples.

A2. Almost the SD clock source is configured as LF:

nrf_clock_lf_cfg_t clock_lf_cfg = NRF_CLOCK_LFCLKSRC;

// Initialize SoftDevice.
SOFTDEVICE_HANDLER_INIT(&clock_lf_cfg, NULL);

If your clock source is internal or others, you may configure the code and sdk_config.h

If your customer board  hardware is not the same with DK, of course you have to define the same I/O, driver as your customer board.

Thank you for replying,

When I try to program with nrf_programmer i get this in log

14:45:08.597

Application data folder: C:\Users\sai\AppData\Roaming\nrfconnect\pc-nrfconnect-programmer

14:45:08.840

Using nrfjprog library 10.12.1, pc-nrfjprog-js 1.7.6

14:45:28.611

Unsupported device. The detected device could not be recognized as neither JLink device nor Nordic USB device.

And i am not able to see device memory layout.

Please use the old version of nrf connect(before 3.6.0). Because it has bug that you mention (device could not be recognized). I also had replied the bug here few weeks ago. Another way you can read by nrfprog command line output to a file.

Hii Henry,

I need few clarification on this

1. Do i need to upload any bootloader code on my CBTMN10 chip which is based on nr52810 module?

2.Which firmware should i upload QFAA with BB0 or QCAA with B00?

3. What if upload any SoftDevice? Will it cause any problem while programming?

Hi 

You need to use some kind of J-Link programmer and connect it to the SWD interface on your module. 

If you have a Nordic development kit (like the nRF52DK or nRF52840DK) you can use this as a programmer, since the DK's come with a debug out port. 

The first picture in this case illustrates how to do this:
