Camera board • I2C Address of V2.1 (IMX219) and V3 (IMX708) Cameras

Hi

We'd like to use the Raspberry Pi V2.1 (Sony IMX219 image sensor) and V3 (Sony IMX708 image sensor) cameras.

We'd though that the IMX708 should appear at address 0x1a on the I2C bus and the IMX219 should appear at 0x10 but on our NXP i.MX 8M Plus board (Debix Model A with Debix I/O board) we get 64 appearing at the following address instead when both the RPi V2.1 and RPi V3 cameras are connected - we were wondering if anyone had any suggestions that could help us understand why both image sensors seem to appear here and not at 0x1a and 0x10? Could they initially appear in a sleep mode and need to be sent a wake up signal to become active?

There weren't any drivers or device tree loaded for the IMX70 or IMX219 when we ran i2cdetect:

i2cdetect -y -a 30a30000.i2c
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: 00 -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- -- 64 -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

Thank you very much for your help!

Will
