Setting up project/jtag/libraries/nfc

[Dajgoro Labinac]

Hi.

This is a bit of a combo question:

I recently got the nRF52 10040 and I'm trying out the included examples on uVision5. I only managed some examples to load on the board, while most others result in an error saying: Error: Flash Download failed - "Cortex-M4"

I don't understand the problem. I just load examples from the example browser, some work, some don't.

Since I got the ble uart peripheral app working I tried transferring the code from the nfc url tag example, but then libraries were missing. In the project explorer of the nfc example there is a nRF_NFC element which I need to add to the other project. I tried fiddling around but cannot find a way to add new elements there. In the end I managed to add it by manually putting it into the project files via notepad. How to add such elements via the IDE?

How is the NFC tag supposed to work? In a video from nordic it works by just putting a device near to the antenna and it starts an app or url. I tried doing that, but nothing ever happens. I tried using nfc tag reader apps, nothing is ever found. Can the NFC be configured as just a regular tag that does not do any particular action, just like a regular plastic tag so other apps can read the data?

1) Make sure that you are using examples configured for the PCA10040 (located in a pca10040 folder). For examples using Bluetooth, you will need to flash the SoftDevice S132. Use nRFgo Studio(Win32 / Win64), and use the "Program SoftDevice" tab. You can find the SoftDevice in

SDK_INSTALL_FOLDER/components/softdevice/s132/hex/

After you have done that, use Keil to flash the example application.

2) Adding files to a project can be done in Keil like this: Right click on a file group in the window Project and click on "Add existing files to Group". As shown in the picture. You also need to include the path for the files added; Options for Target->C/C++->Include Paths.

3) The NFC antenna works as an NFC tag. The open URL example is located in

SDK_INSTALL_FOLDER\examples\nfc\record_url

Here the smartphone/tablet will try to open the URL "www.nordicsemi.com" in a web browser. Make sure that you have turned on NFC on the phone. If you just want to display text, take a look at the Text Record Example.

Thanks for the reply!

For the first problem, seems using that tool manages to load the hex file properly, and now the nfc example which would not load works!

As for the second problem, my project explorer does not look like the one you have shown. In the included link there is a picture of how it looks on my screen, the structure is different and there is no such option. Screenshot

Is this SDK 12.1 ? What version of Keil5 are you using?

[Dajgoro Labinac]

Its uVision 5.21.1.0

Look like maybe you are using CMSIS package? This was deprecated with SDK 11. Please download SDK 12.1 from here.
