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?

    But I have already added the API key as cmake argument, and changed the project ID on the URI as well.

    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)

    I built the application following the documentation. No alteration done to the application.

    Please see your applicaiton.

    I used v2.2.0. Is there a reason for using v1.9.1?
