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.
