I got a question about Nvidia AGX to support new GMSL camera issue.
We have a GMSL camera, where it’s serializer chip’s I2C address is 0x40.
But I notice there’s an existing I2C 0x40 and 0x41 at /dev/i2c-1.
We did use a TCA9546 for a I2C Mux, and remap the 4 deserializer and serializer channels to bus 30. e.g. /dev/i2c-30, /dev/i2c-31, /dev/i2c-32, /dev/i2c-33.
But when I tried to access /dev/i2c-30, the “upstream” i2c devices like 0x40, and 0x41 are still exist at my /dev/i2c-30. This makes my GMSL camera (0x40) undetectable.
Does any one solve this issue before ?
