Part Number: SK-AM62

Hello,

I'm using the E3 SK-AM62 which has an I2C switch between the I2C-2 pins on the Expansion header and also uses a load switch on to enable 3.3V on the expansion header.

I've been having a hard time getting the load switch enabled and talking to this I2C switch. I'm currently on the 08.03.00.19 SDK.

Load switch:

This is on the IO expander on I2C-1 at address 0x22. There is a driver that has already claimed the device here, but it only has one chip GPIO (gpiochip289) associated with it, and I can't really figure out what this is connected to. In either case, the IO expander does not seem to have any of the IO that's described in the users guide actually enabled or configured. How do you actually turn on the load switches on the EVM to enable 3.3V out on the expansion header?

I2C Switch

There is a new I2C switch on I2C-2 to switch between the CSI connector and the user expansion connector. The schematic describes this at I2C address 0x71 but nothing is there, I cannot get i2cdetect to find any device there and it doesn't seem to be timing out which would indicate a bus issue/ driver contention. Any ideas on why I can't talk to this switch at all?

Will there be a how to guide that explains this better in the future?

I have connected the SK-TDA4VM board with fusion board and IMX390. I am following the SDK documentation on enabling the camera: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-sk-tda4vm/08_02_00/exports/docs/getting_started.html#imx390-raw-sensor.

However, I cannot get camera stream from the IMX390. What can I check?
