Software for EVAL-CN0566-RPIZ is not operational.

Category: Hardware
Product Number: CN0566

To whom it may concern,

 

I purchased an Analog Devices EVAL-CN0566-RPIZ on November 25, 2024 (Web Reference No. 2002571687; Order #1001171453), and the order was received on December 4, 2024.  I finally had time to open the package on December 28, 2024 to begin setup and evaluation of the received hardware.

 

I was disappointed that the 6-inch USB-to-Mini USB cable was not sent with the unit to connect the ADALM-Pluto to the Raspberry Pi, so a replacement cable was purchased from Amazon Prime.  Next, the DFRobot HB100 Gravity: Digital 10.525GHz Microwave Sensor (Motion Detection) was Dead on Arrival and had to be replaced with a new unit ordered from Digikey.  The replacement HB100 worked perfectly when connected to a power source.

 

The September 6, 2024 edition of the EVAL-CN0566-RPIZ Quick Start Guide (https://wiki.analog.com/resources/eval/user-guides/circuits-from-the-lab/cn0566/quickstart) was followed to begin the setup and evaluation of the hardware.  This document was approved for release on Sept 6, 2024 by ADI Engineer Mark Thoren.  It appears as though Mr. Thoren did not work through the document to validate its contents before releasing the document.    The instructions in the document have problems that I need assistance resolving, which is the reason for this post.

Regardless, the first step after the hardware is assembled is to load Kuiper Linux 2021_R2 onto the SD Card.  However, the security certificates for Kuiper Linux 2021_R2 have expired, so the required software cannot be downloaded from Github.  Therefore, Kuiper Linux 2023_r2 had to be used for the system software.

 

The following script documents the updates to Kuiper Linux 2023_r2:

IF you are very sure you're only going to be operating headless or by command line and want to speed the boot / shutdown process, run:

sudo systemctl disable x11vnc.service

And then set the Pi to boot to CLI in either the GUI or CLI Raspi-config tool.

A module that was compiled using NumPy 1.x cannot be run in

NumPy 2.0.2 as it may crash. To support both 1.x and 2.x

versions of NumPy, modules must be compiled with NumPy 2.0.

Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

 

If you are a user of the module, the easiest solution will be to

downgrade to 'numpy<2' or try to upgrade the affected module.

We expect that some modules will need time to support NumPy 2.

As you can see, the code downloaded from Github (https://github.com/thorenscientific/rpi_setup_stuff/raw/main/phaser/phaser_sdcard_setup.sh) is not compatible with Kuiper Linux 2023_r2, so the code must be updated or modified to work with Kuiper Linux 2023_r2.  Where on Github can I download the correct revision of the code to work with Kuiper Linux 2023_r2, or can anyone provide me with step-by-step instructions to make the necessary changes to the code?

I am looking forward to your timely reply.

Respectfully,

  • Hi Scott, in the future you can just post the error that you're seeing.  And oftentimes a search for that error on ez.analog.com will uncover the solution.  Mark does an outstanding job helping us use Phaser and its software.  Sometimes libraries change and some engineering debug is necessary.  Mark has addressed the numpy issue found with the new version of Kuiper here:

     ADALM-PHASER Example Python Code Not Working 

  • Dear Jon,

    Thanks for the reply, but I did not find a solution to my problem in this post ( ADALM-PHASER Example Python Code Not Working).  Is the solution to my problem for Kuiper Linux 2023_r2 located in another post?

    Thanks,

    Scott

  • Hi Scott,

    I just updated the wiki page, adding a link to the 2021_r2 Kuiper release:

    https://wiki.analog.com/resources/eval/user-guides/circuits-from-the-lab/cn0566/quickstart?rev=1736188126#sd_cardsoftware_setup

    What happened was newer versions of Kuiper also have a newer version of Matplotlib.

    Did you try this, noted toward the end of the  ADALM-PHASER Example Python Code Not Working thread?: 

    sudo pip install --force-reinstall numpy==1.22

    This should get your 2023_r2 card working.

    Also could you clarify "However, the security certificates for Kuiper Linux 2021_R2 have expired, so the required software cannot be downloaded from Github"? Is this a problem downloading the image, or running the setup script?

    -Mark

  • Dear Kevin,

     

    I downloaded and installed Kuiper Linux 2023_r2 from https://swdownloads.analog.com/cse/kuiper/image_2024-11-08-ADI-Kuiper-full.zip, which was used for demonstrating that it is not compatible with the Python codes, so an update is needed.

     

    Kuiper Linux 2021_r2 can be obtained from https://swdownloads.analog.com/cse/kuiper/image_2023-04-02-ADI-Kuiper-full.zip, and cannot be updated with the Gihub link because the security certificates have expired.

     

    Every available version of Kuiper Linux can be obtained online at https://wiki.analog.com/resources/tools-software/linux-software/adi-kuiper_images/release_notes.

     

    The URL you provided, https://swdownloads.analog.com/cse/kuiper/image_2023-04-02-ADI-Kuiper-full.zip, cannot be used since the security certificates have expired, so downloads from Github are refused for this reason.  This is why I used Kuiper Linux 2023_r2.  What do I need to do to make Kuiper Linux 2023_r2 compatible with the Python codes for using the system?

     

    Respectfully,

     

    Scott

  • Hi Scott,

    Try running this command:

    sudo pip install --force-reinstall numpy==1.22

    This will downgrade the numpy version and should fix the compatibility issue.

    -Mark

  • Also I just downloaded 2021_r2, burned a fresh SD card, and ran the setup script. It went cleanly, with no errors.

    Can you paste the exact errors you're seeing that are related to expired security certificates?

    -Mark

  • Dear Kevin, Mark, and Jon,

     

    Please accept my apology for the late reply, but the snow and ice storm in Western Kentucky have impeded work on several projects.  Arctic air arrives today, so the next few days will be a lot colder than normal, so hopefully, we do not lose power or Internet access.

     

    Let’s start by benchmarking the system before the change you suggested on Monday, January 6, is implemented.  Here is how the original system behaves for the following two commands:

     

    cd ~/pyadi-iio/examples/phaser

    python phaser_find_hb100.py

     

    analog@phaser:~ $ cd ~/pyadi-iio/examples/phaser

    analog@phaser:~/pyadi-iio/examples/phaser $ python phaser_find_hb100.py

     

    A module that was compiled using NumPy 1.x cannot be run in

    NumPy 2.0.2 as it may crash. To support both 1.x and 2.x

    versions of NumPy, modules must be compiled with NumPy 2.0.

    Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

     

    If you are a user of the module, the easiest solution will be to

    downgrade to 'numpy<2' or try to upgrade the affected module.

    We expect that some modules will need time to support NumPy 2.

    Can you provide any information for how to use the Python codes with the default Kuiper Linux 2023_r2?  Do you have step-by-step instructions for compiling the Python codes to work with the default Kuiper Linux 2023_r2 configuration?

     

    Thanks,

  • Dear Mark,

     

    I downloaded a copy of Kuiper Linux 2021_r2 from https://swdownloads.analog.com/cse/kuiper/image_2023-04-02-ADI-Kuiper-full.zip, and uploaded the image to a SD Card using rufus_4-6 (https://rufus.ie/downloads/#google_vignette). 

     

    Here are the startup screenshots and dialogue for Kuiper Linux 2021_r2:

     

     

     

    Running the first command creates the expired security certificate problem:

     

    Wget https://github.com/thorenscientific/rpi_setup_stuff/raw/main/phaser/phaser_sdcard_setup.sh

     

     

     analog@analog:~ $ wget github.com/.../phaser_sdcard_setup.sh

    Does this help with resolving the problem with attempting to use Kuiper Linux 2021_r2?  If not, what additional information do you need from me?

     

    Thanks,

  • A little googling led me to two non-EZ forum discussions with potential solutions to the Github certificate issue:

    DeandrePetersen at https://github.com/orgs/community/discussions/112148 suggested:

    Ensure that the system date and time on your machine are correctly set. If the system clock is incorrect, SSL certificates may appear as not yet valid or expired. Correcting the date/time settings should resolve the issue in many cases. If the system date/time is correct, check the expiration date of the SSL certificate associated with the server you're trying to connect to. If the certificate has expired, it will need to be renewed or replaced. Ensure that the SSL certificate presented by the server is properly signed by a trusted Certificate Authority (CA) and that the entire certificate chain is valid. Sometimes, an incomplete or misconfigured certificate chain can cause validation errors.

    Another option I read over at https://forums.fogproject.org/topic/11343/certificate-of-github-com-is-not-trusted is you can add "--no-check-certificate" to the end of your wget command.
