Re: i2c0 dual camera and HAT eeproms

I thought that on B+ the CAM is connected through i2c0 on GPIO 28,29
and that during boot the firmware first looks at GPIO 0,1 for an EEPROM and then switch the i2c0 to GPIO 28,29. As i2c0 can't be enabled on both 0,1 and 28,29 at the same time.
Correct me if I'm wrong

Re: i2c0 dual camera and HAT eeproms

Thanks for the quick reply. I was thinking that during boot the firmware expects to have only an eeprom conected to ic20. So I only have to make sure that GPIO0 and 1 don't get turned off after the boot process. PS: Why exactly must the two cameras be conected to two different i2c0 pin Because if I ...

i2c0 dual camera and HAT eeproms

Hi all i'm actually working on a project using the compute module. I try to provide a RPi B+/2B compatible pin header and two camera (CSI) ports. From the documentation I know that each camera must have different i2c0 pins. My configuration is: CAM0 CD0_SDA to GPIO28 CD0_SCL to GPIO29 CAM0_IO1 to GP...
