Merging two examples in SDK14

[Dajgoro Labinac]

Hi,

I've been working with SDK11, and now I have to move my project to SDK14 due to some issues with the old SDK.
In SDK11 I could just use Keil's "Manage Run-Time Enviroments" dialog to add whatever libraries I needed, and it worked.

Now I've started moving all my code to SDK14 and things don't work as they did, and now I'm trying to get the same code working.

I've started by taking the ble_app_uart example and adding to it the record_url example. I merged the required code, I went in the project options
under C/C++, ASM and appended the library paths there, but it still does not work, I keep getting:

linking...
.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol nfc_t2t_emulation_start (referred from main.o).
.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol nfc_t2t_payload_set (referred from main.o).
.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol nfc_t2t_setup (referred from main.o).
.\_build\nrf52832_xxaa.axf: Error: L6218E: Undefined symbol nfc_uri_msg_encode (referred from main.o).
Not enough information to list image symbols.

I even tried merging the makefiles.

Also where did the nrf_drv_config.h file go?
Where do I now enable peripherals?

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.

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.

[Jørgen Holmefjord]

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?

[Dajgoro Labinac]

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.

[Jørgen Holmefjord]

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

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

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

[Dajgoro Labinac]

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?

[Jørgen Holmefjord]

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.

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.
