iMX6ULL SPI Bus Enabling

[BlackCableSociety]

Hello,
Until now I used some Colibri iMX6ULL 512MB WB IT V1.0A with an Image that I built a long time ago (around 2018, Angström) with a number of cryptic commands from a toradex documentation. That time I was able to enable the SPI bus by changing the status in the imx6ull-colibri-eval-v3.dtsi. This Image is not working correctly with a Colibri iMX6ULL 512MB WB IT V1.1A, the Wifi module is not usable.
The Wifi is essentail for my application as well as the SPI bus.

I tried my best with the current documentation:

Build a Reference Image with Yocto Project/OpenEmbedded | Toradex Developer...

There were a number of “challenges” during the process. I am using a virtual machine with a Unbuntu 22.04 and had to resize it for the image building process (got some errors, deleted some files, resized, restarted process…). My current status for the
“bitbake tdx-reference-minimal-image” command is this output:

1. How to fix this?
2. Where is the .dtsi file to find to enable the SPI bus?
3. Which files do I need to copy to a USB stick to install it on the module with the ToradexEasyInstaller?
4. Where can I find these files?

I would not like to be a Yocto expert, my intention is to develop/improve my C application for the module.
Hopefully the old fashioned way with eclipse is still working with the new image and Colibri V1.1A (for the old one it works, Colibri V1.0A). I need some advice, please help.

Best Regards
Erik

Hello Erik,

Thank you for reaching out with your questions about the Colibri iMX6ULL 512MB WB IT V1.1A module. Let’s address each of your concerns:

1. Fixing the Yocto Build Error:
   The error message indicates that ‘cmake’ is not installed on your Ubuntu system. You can resolve this by installing ‘cmake’ with the following command:

   sudo apt-get install cmake
   

   After installation, please try running the bitbake tdx-reference-minimal-image command again.

2. Enabling the SPI Bus:
   To enable the SPI bus, you need to modify the device tree source file. Look for the imx6ull-colibri-eval-v3.dtsi file in your build environment. Ensure the SPI node’s status is set to “okay” like this:

   &ecspi1 {
       status = "okay";
   };
   

   After making these changes, rebuild your image to apply them.

3. Files for Toradex Easy Installer:
   Once your image is built successfully, the necessary files will be located in the deploy/images/colibri-imx6ull/ directory of your Yocto build environment. You will need the .tar file for the Toradex Easy Installer.

4. Using Toradex Easy Installer:
   Copy the .tar file to a USB stick. Then, boot your Colibri module into recovery mode and use the Toradex Easy Installer to flash the new image onto the module.

I hope this helps you get your system up and running. If you have any more questions, feel free to ask.

Best regards,
Toradex AI Assistant

Colibri iMX6 ULL - Enabling SPI bus support

Hello, I am working to figure the steps needed to enable SPI on a Colibri iMX6ULL (512MB NAND FLASH). So far, I have tried adding spitools and spidev-test to my image recipe, however, when inspecting /dev/ I see no SPI devices. Troubleshooting using dmesg shows the following: root@colibri:~# dmesg | grep -i spi [ 13.925870] platform 2008000.spi: deferred probe pending [ 21.694301] mcp251x spi0.0: MCP251x didn't enter in conf mode after reset [ 21.722929] mcp251x spi0.0: Probe failed, e…

Flash/Update kernel on viola board

It have been a while since I last worked in embedded and never worked with toradex modules so I am a bit lost to set up flexcan on a Colibri iMX6ULL with a Viola carrier board. I was able to install the torazon linux image BSP 3 with easy installer via vnc. I was able to setup the sdk and build a hello world app and run on the board. I was able to create a recipe and use bitbake to build a package for the hello world app. I was able to follow the instructions at CAN (Linux) | Toradex Develop…

Thanks, but cmake is installed (3.22.1-1ubuntu1.22.04.2) the error is still there. Do you need additional log files?
