How to resolve a build error in Zephyr while building the Edge Impulse precompiled sample for Thingy 53.

[Sachin Rawat]

Hi

I was working on an application sample for some days named "Machine learning" which is located at nrf/application, but facing a huge amount of issues connecting the board to edge impulse studio.

So while searching for the answer I found  https://devzone.nordicsemi.com/f/nordic-q-a/93706/nrf-edge-impulse/394830 this ticket, and in this ticket, they have given "edge impulse precompiled for thingy53", link of that is https://github.com/edgeimpulse/firmware-nordic-thingy53 

1. Should I need to use this sample instead of a machine learning sample for working with edge impulse?

I have downloaded and tried to create a build using this sample, but I am facing a build error 

D:/firmware/zephyr/drivers/ipm/ipm_nrfx_ipc.c: In function 'vipm_nrf_0_set_enabled':
D:\firmware\zephyr\include\devicetree.h:305:40: error: 'DT_N_INST_0_nordic_nrf_ipc_IRQ_IDX_0_VAL_irq' undeclared (first use in this function)

D:/firmware/zephyr/drivers/ipm/ipm_nrfx_ipc.c: In function 'gipm_init':
D:\firmware\zephyr\include\devicetree.h:305:40: error: 'DT_N_INST_0_nordic_nrf_ipc_IRQ_IDX_0_VAL_priority' undeclared (first use in this function)

I have not made any changes to the sample and I am unsure why this error is occurring in the default sample.

Can you help me resolve this issue?

Hello, 

So while searching for the answer I found  https://devzone.nordicsemi.com/f/nordic-q-a/93706/nrf-edge-impulse/394830 this ticket, and in this ticket, they have given "edge impulse precompiled for thingy53", link of that is https://github.com/edgeimpulse/firmware-nordic-thingy53

The Thingy:53 comes pre-installed with the firmware to work with the nRF Edge Impulse app for iOS and Android. This is the Edge Impulse (edge_impulse_1.0.0_thingy53_nrf5340.zip) found in the precompiled package found under the downloads tab for Thingy:53 product page.

I was working on an application sample for some days named "Machine learning" which is located at nrf/application, but facing a huge amount of issues connecting the board to edge impulse studio.

In order to connect this sample to the Edge Impulse Studio you will need to forward data using Edge Impulse own data forwarder. To forward the collected data using Edge Impulse’s data forwarder, you must install the Edge Impulse CLI. See Edge Impulse CLI installation guide for instructions. When building the nRF Machine Learning application for Thingy:53 is requires to use NUS to communicate with an additional development kit that is able to run the Bluetooth: Central UART sample.

Please see Data Forward Requirements for more information.

Kind regards,

I know, I have heard this many times, but it is actually different in practical

The already flashed thingy53 is having different hex in it

and this precompiled is different, I have tested it. The LEDs are not showing the same behaviour as well as the edge impulse code from the downloaded precompiled code is not even advertising

I have completed all the steps as described in the https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/machine_learning/README.html

As well as followed this https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_edge_impulse.html#adding-edge-impulse-model-to-the-ncs

https://docs.edgeimpulse.com/docs/development-platforms/officially-supported-mcu-targets/nordic-semi-thingy53#updating-the-firmware

But nothing works for me.
The error on cmd when I run edge-impulse-daemon is indicating that I am not able to provide the API key, device ID, and device type. 

And can you please help me in resolving that error too?

Hello, 

Using the out-of-box configuration of nRF Machine Learning, built for the Thingy:53 and connecting it to my nRF52840DK running Bluetooth: Central UART, I get the following output when connecting to Edge Impulse

Note that I have tested the connection in the background to a PuTTy terminal to verify data. This is enabled by long pressing the button on the Thingy:53 putting it in Data Forwarder modus.

Do you have a user on Edge Impulse Studio? If so, do you have a project to where you have collected data and trained your model? Adding the API in your project should download this model and add to your project.

What version of nRF Connect SDK are you running?

Kind regards,
Øyvind

Fabulous, This is what I want. 

Okay, now I know what will be successful connectivity will look like.

Please help me more by by sharing

1. What are the complete steps or add on you have done in the default sample, so that you are not facing the error like API key, deviceID and devicetype.

2. Please share your prj.conf, and show me the actual line what you have passed as an cmake argument for API key(you can make this ticket private in order to share the confidential  data but I need the actual thing)

Øyvind said:

Do you have a user on Edge Impulse Studio?

Yes, I have and it is private account.

Øyvind said:

Yes, I named it as 

Øyvind said:

What version of nRF Connect SDK are you running?

ncs v1.9.1

This is what I get when I tried 

Your assistance would be greatly valued.
