Hi,everyone!

I just read the datasheet of j106. And i found that TX1 use three i2c bus (device 0\2\6).

But in the list of csi connector.
CSI-A use I2C0_CLK(E15) I2C0_DAT(D15)
CSI-B use I2C0_CLK(E15) I2C0_DAT(D15)
CSI-C use I2C_CAM_CLK(E15) I2C_CAM_DAT(D15)
CSI-D use I2C_CAM_CLK(E15) I2C_CAM_DAT(D15)
CSI-E use I2C_PM_CLK(A6) I2C_PM_DAT(B6)
CSI-F use I2C_PM_CLK(A6) I2C_PM_DAT(B6)

Dose it wrong? CSI-C and CSI-D should use I2C_CAM_CLK(C6) I2C_CAM_DAT(D6)?

Regards,
YMY

The i2c bus is used for communicating with camera sensor it doesn’t need to have any relationship wit the CSI BUS.

Hi shaneCCC

I need I2C bus to congifuration the register of imx219（pi camera ）.
and I see it use I2C bus in imx219’s driver.

and I see the I2C address of A\C\E is 0x10 in the dts ofj106.
the I2C address of B\D\F is 0x12(it use I2C address translator ).
I think if ABCD in the same I2C bus, it will be address conflict.

Thanks!

I believe they may connect to a i2c expander. You should as ask to get schematic to check it.
