I am having a problem with I2C bus 7 timeout when I have the TX2 camera interface board installed and two Allied Vision Alvium cameras. With Jetpack 5.0.2 installed and the T2X interface connected I get I2c timeouts when I run sudo i2cdetect -y -r 7. If the board is removed then the scan runs fast and detects only the audio chip at x1A.
