That was a while ago, so I don't remember anymore what was the solution.
But one of the issues with how keil works is that you have to add the paths to the library in more than one place to get it working. Also you must have the correct version of the library itself otherwise it wont work either.

I am suffering from the same error as you in the past.

.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol nfc_t2t_emulation_start (referred from main.o).

I tried to integrate on the same sdk, but an error occurred. If you add some C files to the project window as in the record_text example, i do not see "undefined symbol" errors, but got a new error that "nfc_t2t_lib_keil.lib could not open." Could you explain how I solved it? Help is urgent ...

Hi, I did try that before but I did not have much luck.
I tried now again, and I got it working but only on SDK14 for some reason.
Ok, seems it works now, thanks for the support.

You can check the IC revisions, SDK, and SoftDevice compatibility matrix for nRF52832, nRF52840, nRF52810, and nRF51 series. The softdevices supported by each SDK version is also given in the top of the introduction chapter in the documentation.

The supported softdevice hex-files are located in components\softdevice\SoftDevice\hex subdirectory in the SDK.

I did try with the softdevice too, but I have a feeling I've been using the wrong version.
Where can I find the correct softdevice hex for each sdk?

You are missing the step where you are flashing the softdevice. Which example are you testing with?

Hi,

I got another devboard, and nothing works.
This means that I'm doing something wrong.
Can you list all the steps required to get the example working, what I did was:

-Download the sdk zip
-Unpack it
-Go into the example folder
-Open the PCA10040 keil project
-Modify NRF_SDH_CLOCK_LF_SRC and the parameters below in sdk_config.h
-Click build
-Click Load
-Open RTT Viewer
-Connect
-(nothing happens)
-Restart the board, and reconnect RTT

Are you sure you mounted the crystal correctly? Please try with another board if you have available.

RE: Merging two examples in SDK14

Dajgoro Labinac — Tue, 06 Mar 2018 14:29:55 GMT

I get nothing at all even with that.
I'm starting to think that my devboard might be deffective since I placed back the crystal and redownloaded a fresh copy of the SDK14 and nothing works on it anymore.

RE: Merging two examples in SDK14

Please use this method to check error code. If the device restart, you might not get any info on RTT. Is logging enabled on RTT for your application?

RE: Merging two examples in SDK14

Dajgoro Labinac — Tue, 06 Mar 2018 13:06:10 GMT

I get nothing at all via rtt, just black screen.

The identical code works on the devboard, I removed the crystal from the devboard and I got it working once, but I can't get it working anymore.

Jørgen Holmefjord — Tue, 06 Mar 2018 11:39:12 GMT

Did you try debugging as I suggested above? What is the error code (if any) and where is the application stuck?

Hi,
Thanks for the reply.
I've talked to Sigurd about the issue, and he gave me new settings which have NRF_SDH_CLOCK_LF_XTAL_ACCURACY is set to 1 and nothing changes.
I don't think the issue is with this settings, something else is probably causing it not to work, and I can't figure out what. I could try removing the crystal from the devboard and see if I can get it working then.

RE: Merging two examples in SDK14

You should set NRF_SDH_CLOCK_LF_XTAL_ACCURACY to 0 or 1. This parameter is used for both external XTAL and RC oscillator in s132 v5.0.0 softdevice (which is used in SDK 14.x.0). Setting it to 7 will cause the softdevice to expect accuracy of 20PPM, which the RC oscillator cannot provide. This is from s132 v5.0.0 release notes:

New functionality

SoftDevice
- The RC oscillator accuracy can now be set to any of the defined NRF_CLOCK_LF_ACCURACY values, and there is no default anymore. In other words, the nrf_clock_lf_cfg_t::accuracy parameter now has the same functionality when used with the RCOSC clock source as with the XTAL clock source (DRGN-8666).

Hi,

Thanks for the reply.
In the SDK11 I did the following modifications to the example, and that is all thats required to get it working on my board which does not contain a 32.78kHz crystal and DC-DC converter:
SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_RC_250_PPM_4000MS_CALIBRATION, NULL);
And:
NRF_POWER->DCDCEN = 0;

On the SDK14 example I modified the sdk_config.h like this:

//==========================================================

// <h> Clock - SoftDevice clock configuration

//==========================================================
// <o> NRF_SDH_CLOCK_LF_SRC  - SoftDevice clock source.
 
// <0=> NRF_CLOCK_LF_SRC_RC 
// <1=> NRF_CLOCK_LF_SRC_XTAL 
// <2=> NRF_CLOCK_LF_SRC_SYNTH 

#ifndef NRF_SDH_CLOCK_LF_SRC
#define NRF_SDH_CLOCK_LF_SRC 0
#endif

// <o> NRF_SDH_CLOCK_LF_RC_CTIV - SoftDevice calibration timer interval. 
#ifndef NRF_SDH_CLOCK_LF_RC_CTIV
#define NRF_SDH_CLOCK_LF_RC_CTIV 12
#endif

// <o> NRF_SDH_CLOCK_LF_RC_TEMP_CTIV - SoftDevice calibration timer interval under constant temperature. 
// <i> How often (in number of calibration intervals) the RC oscillator shall be calibrated
// <i>  if the temperature has not changed.

#ifndef NRF_SDH_CLOCK_LF_RC_TEMP_CTIV
#define NRF_SDH_CLOCK_LF_RC_TEMP_CTIV 2
#endif

// <o> NRF_SDH_CLOCK_LF_XTAL_ACCURACY  - External crystal clock accuracy used in the LL to compute timing windows.
 
// <0=> NRF_CLOCK_LF_XTAL_ACCURACY_250_PPM 
// <1=> NRF_CLOCK_LF_XTAL_ACCURACY_500_PPM 
// <2=> NRF_CLOCK_LF_XTAL_ACCURACY_150_PPM 
// <3=> NRF_CLOCK_LF_XTAL_ACCURACY_100_PPM 
// <4=> NRF_CLOCK_LF_XTAL_ACCURACY_75_PPM 
// <5=> NRF_CLOCK_LF_XTAL_ACCURACY_50_PPM 
// <6=> NRF_CLOCK_LF_XTAL_ACCURACY_30_PPM 
// <7=> NRF_CLOCK_LF_XTAL_ACCURACY_20_PPM 

#ifndef NRF_SDH_CLOCK_LF_XTAL_ACCURACY
#define NRF_SDH_CLOCK_LF_XTAL_ACCURACY 7

And also disabled the UART initialization because I'm not using it.

After that I would click build and program the board.

Am I missing a step?

Are you getting any errors? If not, what is the symptoms showing it is not working on your board? What did you change in sdk_config.h? Note that the clock settings for the softdevice is configured in the parameters described on this page, not using the clock driver config. Pleae try to debug the application and report back any error codes you are seeing.

I finally got it to work on the devboard, but now I need to get it working on my board, on which everything works fine with the SDK11.
On my board I don't have the 32.768kHz crystal so I need to enable the RC oscillator, also no DCDC converter.
I did try setting the sdk config file, but its still not working.
I removed the UART initialization since the RX pin is left floating, but that did not change anything.

Ok, I got it to compile, but something is not working, something else is now wrong.

RE: Merging two examples in SDK14

Dajgoro Labinac — Thu, 01 Mar 2018 12:49:05 GMT

Yes, trying to copy over parts of the sdk_config.h now, but its a bit non obvious what I need and what I don't.
To add the libraries I added the paths to three different places, including the "Manage project items..." dialog.
Is there a single place where I can just put the library paths without having to duplicate the path?

Hi,

you need to define your configuration in sdk_config.h as same as nrf_drv_config.h
