I’m sorry for my stupid question.
I want to set the PIN’s description at the boot:
for example I want to set the SODIMM 28 as GPIO input and in my image this PIN is set as rawnand.DQS, you can see the PIN description option in the attached image. : /community/storage/temp/2562-screenshot.png
If I change manually the value with GPIO-TOOL as GPIO and INPUT.
I can read right the value of the PIN using teh follwoing lines:
for your information the BSP Version 2.8 will soon reach end of life and will not be supported anymore. Please consider moving to BSP3.0.4 (LTS) or our newer production release of BSP 5.1.0.
It is also recommended to change your application for handling the GPIOs. Using the sysfs environment for handling will be discontinued from the mainline kernel. The current approach for this is by libgpiod .
Your approach still works. As alex already stated you need to set proper pinmuxing, where you can also enable the pullup resistor. See attached the changes you need to do in the device tree.
thank for your support.
Now, I’m starting to use the new production release toradex_5.4-2.3.x-imx.
I changed my tree and copy the zImage and imx6ull-colibri-eval-v3.dtb
I tried the Colibri-iMX6ULL_Reference-Multimedia-Image-Tezi_5.2.0-devel-202102+build.7
but I had any errors on the boot image, so I used the Image Colibri-iMX6ULL_Reference-Minimal-Image-Tezi_5.2.0-devel-202102+build.7
I want to auotogin at the start of the device
what do I do to autogin?
Coud you suggest me any other image compatible with toradex_5.4-2.3.x-imx.?
I see your using the Downstream kernel, which is a good choice.
Some instability is to be expected from the monthly builds. Did you try to use a newer “nightly” build?
It would be interesting and helpful for us, if you could state the errors you encountered while working with Colibri-iMX6ULL_Reference-Multimedia-Image-Tezi_5.2.0-devel-202102+build.7. Can you post some information on them?
Let me know if you had success with the nightly build.
I tried a night version (Toradex Embedded Linux Reference Multimedia Image 5.0.0+build.3)
and it’s starting correctly without the login request.
However I don’t have the SPI device: the can is disbaled and the spi is enable, in this case I don’t have CAN driver on dmesg log (see this attachmentlink text) and I attached the git diff log link text
Could you give me why I don’t have the SPi devices?
