Hello All,
I have an Apalis IMX8 Quad Plus with an apalis toradex evaluation carrier board. I am using Yocto, easy installer to write image
I build yocto apalis acorcing to bellow link
https://developer.toradex.com/linux-bsp/how-to/build-yocto/build-a-reference-image-with-yocto-projectopenembedded/
and make image minimal using
bitbake core-image-minimal

but when use

 ls -l /dev/apalis-spi*

result of it is::

ls: /dev/apalis-spi*: No such file or directory

but when i write to emmc

it works without anyy error

thanks in advance

Greetings @hhami,

The SPI entries /dev/apalis-spi* are symlinks to the actual SPI devices. These symlinks are added in our images via yocto recipes as seen here: 99-toradex.rules « apalis-imx8 « files « udev « recipes-core - meta-toradex-bsp-common.git - Toradex BSP layer, recipes common to all modules

The image recipe core-image-minimal is not a Toradex provided OS image. Which is why the resulting image built from this recipe does not have these syminks in /dev. Perhaps you meant to build the recipe tdx-reference-minimal-image, which is the recipe for our minimal reference image?

Best Regards,
Jeremias
