radxa zero 3e, yocto linux 6.13, imx287

nkos

@veye_xumm yeah, I know that and I mentioned it in my question

And, as I mentioned, I cannot use it, so the question is not about the list of currently supported kernel versions, but how to use your camera on yocto, especially: how to adopt dtsi for 6.13 or how to use 5.10/6.1 kernels with yocto and radxa zero 3e

veye_xumm

@nkos Understood, I will arrange to interface with the new version of the kernel. It will take a few days.

nkos

@veye_xumm that would be great, thank you very much in advance

nkos

@veye_xumm could you please tell if there are any updates?

veye_xumm

@nkos Apologies for the delay. I've just returned from the National Day holiday and will follow up on this matter as soon as possible.

@nkos Our driver code is developed based on Radxa's BSP, and the BSP development documentation can be found at the following URL:
https://docs.radxa.com/en/zero/zero3/low-level-dev/kernel

To address the issue you raised, we attempted to set up a Yocto development environment for the Radxa ZERO 3. Unfortunately, we were unsuccessful in this endeavor.

Later, we noticed Radxa's documentation regarding building Linux images with Yocto:
https://github.com/radxa/yocto-manifests

In the "List of Radxa Boards supported" section, the Radxa ZERO 3 is not listed among the supported development boards.

Therefore, we do not recommend using Yocto to build a Linux image for the Radxa ZERO 3.

I wonder if there are other options to build newer kernels for radxa zero 3e. Building yocto to adopt the driver to a particular kernel version looks like an overkill and I cannot ask you to do that

Just in case you're interested, I've prepared a small guide showing how to build yocto for radxa zero 3e:

https://kostovsky.me/blog/yocto_qt_on_radxa_zero_3e/

I'll try stock radxa distro

@nkos I will attempt to build a 6.x version system based on the original BSP approach.

@veye_xumm hi, did you have any chance to take a look at this? it would be nice to have an easy option to modify and build driver with up to date kernel on current radxa debian and/or on yocto

the main goal I'm trying to achieve is to configure any registers that aren't available in your kernel's driver (a lot of them)

for example, the flash delay relative to the input trigger (if it's possible at all, it could be very useful in laser devices; negative or positive - not so important)

@nkos

Sorry, regarding the attempt to port the camera to the Radxa Zero 3 + 6.x, we tried to set up the standard build environment but were unable to compile successfully. I posted a question on the Radxa forum, but have not yet received a follow-up response.

As for the method you mentioned to configure our registers, we recommend that you do not use the driver. Instead, please use our mv_mipi_i2c.sh script.
