Hi Ed,

Sorry for the late reply.

[quote user="CktDesigner"]However, when compiled, and Debug->Go is clicked, execution halts at line 455 of init.c with no particular error reported. [/quote]

After this step, press "Restart" () in the debug section, then "Go".

[quote user="CktDesigner"]1. What is the difference between the preview and production versions of nRF5340-(p)DK?[/quote]

The hardware version is different. There are differences (like more peripherals, different number of MPU regions, different size of flash regions in SPU) are between hardware version.

[quote user="CktDesigner"]2. Is there a link (that I have missed) that documents the SoC peripheral drivers/libraries for the nRF5340 under nRF Connect? In particular, I am using the TWI and SPI transaction managers and I2S drivers in my nRF52840 applications.[/quote]

I don't find the document like that either, but I will suggest the internal. This case https://devzone.nordicsemi.com/f/nordic-q-a/58966/is-there-any-sample-for-spi-based-on-nrf5340 shows how to use SPI on nRF5340.

[quote user="CktDesigner"]3. Is the online documentation for nrfx v2.4.0 (in the Infocenter) still relevant for nRF Connect / Zephyr (I assume so)? Assuming so, are the libraries (such as TWI/SPI transaction managers) available under nRF5 SDK usable under SDK Connect/Zephyr?[/quote]

Check here: http://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/kconfig/index-nrf.html#

[quote user="CktDesigner"]4. Is there a link that defines all of the CONFIG_* settings that can be populated in prj.conf?[/quote]

See this doc http://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/kconfig/index.html

[quote user="CktDesigner"]5. Is there a chart/link that cross-references which CONFIG_* settings are required for particular device drivers? For example, if I want to use TWI (or TWIM) peripherals, which CONFIG_ settings are required/optional?[/quote]

You can take a look at this tutorial https://devzone.nordicsemi.com/nordic/nrf-connect-sdk-guides/b/getting-started/posts/nrf-connect-sdk-tutorial---part-3-ncs-v1-4-0

[quote user="CktDesigner"]6. Even after "rebuilding" a solution, often when I click Debug->Go, the "Project out of date" dialog box appears. Is there some setting in SES that needs to change when using nRF Connect to avoid this?[/quote]

If you already rebuild the solution, you could ignore it and not build again.

[quote user="CktDesigner"]So there seems to be an issue running some of these sample programs on the 0.8.0 version of the nRF5340-PDK.[/quote]

Do you flash the Bluetooth: HCI RPMsg sample to the network core and bluetooth/peripheral_hr sample to the application core?

Do you get the log from the terminal tool? See How to connect with PuTTY for the required settings.

Hi Amanda,

One other thing... I tried the bluetooth/peripheral_hr sample and had the same issue. So I tried it on the nRF52840-DK board I had and it worked. So there seems to be an issue running some of these sample programs on the 0.8.0 version of the nRF5340-PDK.

Since I'm using these as a primer on using the nRF5340 and Zephyr, I notice that Zephyr provides drivers for many peripherals (I2C, SPI, etc.) but these are also provided in the nrfx library from Nordic. Which set is recommended by Nordic (I assume that nrfx is more complete and will work better!)?

Thanks!

Hi Amanda,

Thanks for your response!

My nRF5340-PDK is version 0.8.0

I deleted the project build directory for "Hello World" and re-created the project making sure to select nrf5340pdk_nrf5340_cpuappns as the target. I also edited the prj.conf file to include the statements you provided (and in the link you pointed to).

However, when compiled, and Debug->Go is clicked, execution halts at line 455 of init.c with no particular error reported. If I click the Run icon, it halts again at line 80 of fault_s.S Not sure how to proceed...

A few additional questions:

1. What is the difference between the preview and production versions of nRF5340-(p)DK? Note that when I first powered on the board, it prompted me that new firmware was available (I assume for the debugger) and I allowed the download to occur. Is this OK? Are there physical differences in the board design?

2. Is there a link (that I have missed) that documents the SoC peripheral drivers/libraries for the nRF5340 under nRF Connect? In particular, I am using the TWI and SPI transaction managers and I2S drivers in my nRF52840 applications.

3. Is the online documentation for nrfx v2.4.0 (in the Infocenter) still relevant for nRF Connect / Zephyr (I assume so)? Assuming so, are the libraries (such as TWI/SPI transaction managers) available under nRF5 SDK usable under SDK Connect/Zephyr?

4. Is there a link that defines all of the CONFIG_* settings that can be populated in prj.conf?

5. Is there a chart/link that cross-references which CONFIG_* settings are required for particular device drivers? For example, if I want to use TWI (or TWIM) peripherals, which CONFIG_ settings are required/optional? (Even when using nRF5 SDK and sdk_config.h (with or without the CMSIS wizard) with the nRF52840, it is sometimes trial/error to figure out which settings are needed)

6. Even after "rebuilding" a solution, often when I click Debug->Go, the "Project out of date" dialog box appears. Is there some setting in SES that needs to change when using nRF Connect to avoid this?

Many thanks!

Hi Ed,

What is the HW version on the withe sticker of your PDK? Is it 0.8.0 or 0.9.0?

nRF5340 is only supported by the nRF Connect SDK.
See the explanation in this post.
b. Refer to how-to-use-rtt to add the following to the prj.conf under ncs\zephyr\samples\hello_world as:
```
CONFIG_SERIAL=y
CONFIG_USE_SEGGER_RTT=y
CONFIG_RTT_CONSOLE=y
CONFIG_UART_CONSOLE=n
```
c. Press reset. and go again. It will stop at main.c line 118 : err = bt_enable(NULL);
d. The application sample like peripheral hr only can run with nrf5340pdk_nrf5340_cpuapp or nrf5340pdk_nrf5340_cpuappns. If you want to run the sample with nrf5340pdk_nrf5340_cpunet, please see network-sample.
