Can I get imx462 mipi camera driver?
Is it true that imx462 and imx290 are the same?
I think I need to use various mipi cameras. Can you tell me how to develop my own drive?

First of all, I would appreciate it if you could tell me the imx462 standard driver or provide an existing driver if you have one.

@george Thank you for your reply.I would appreciate it if you could explain in more detail.I know how to boot from USB, but how do I format emmc?

If you look at the serial log while installing Ubuntu, you will see a message saying that the emmc partition is broken, and it will stop.What should I do?This problem occurred after installing Ubuntu using balenaEtcher.

@jack_admin The attached log records are all. Even if I reboot again, I only see the log with the same content. Is it possible to control the booting state from serial mode? Other boards can enter control mode using key values. What should I do with cm5?

@george I updated the OS by connecting to the top of the USB3.0 blue connector.

If you write ubuntu22.04 to emmc in UMS mode and reboot, serial data will appear as above.
And only the logo appears on the screen.
It continues to be like this.What should I do?I would like to ask for your advice.have a good day.

@george It went into UMS mode and ran several times in Windows, but only the logo appeared.Thank you for your reply.

@george Thank you for your reply. have a good day.

I installed ubuntu 22.04 version 20230606-ubuntu-22.04-preinstalled-desktop-arm64-cm5-evb-v11.img on emmc on CM5 EVB according to the manual. When I turn off the power and reconnect it, only the logo appears.
I've had power issues before, so I'm using a 12V 3A adapter.
I heard that there is a way to check with serial, so I would appreciate it if you could tell me how to do it.

@george Thank you. Have a good day.

@george Thank you. Please tell me the download address.

An error occurs when converting the yolo v8 model to onnx and then to rknn.
The error message is -> "DatainEntries overflow, need to tiling more, datain_entries: 2114, limitation: 2048"
Although converted to rknn, the model fails to load.Is there a way to reduce the model size?

I tried referring to several sites, but none of them gave reasonable information.
Even if I try to use a Docker image, I cannot download it from Baidu.
Please share your advice and materials. Thanks for reading.
have a good day.

There is a source that uses the YOLO v8 model to find objects and draw boxes using the video received from the webcam. I would like to convert it to the RKNN model and run it. Please tell me how.

@george Thank you for your reply.

I'm trying to install pytorch and torchvision, but when I find and install torch-1.8.1-cp37-cp37m-linux_aarch64.whl and torchvision-0.9.1-cp37-cp37m-linux_aarch64.whl, it says the platforms are different.
I'd like to ask for your advice.
thank you have a good day.

@george Yes... it has been resolved. It was a cable connection problem. thank you

@etrin The problem occurred because the monitor HDMI cable was not connected properly.

Now I fully understand the problem. Please refer to this part for others as well.
