Hello
We use C3708 for our CPU ,after we detect i2c in Linux shell.We found that there is an address we don't define, but always show in our i2c result.That address is 0x08. I want to ask what is that address? Is this address that originally existed in the C3708?
Thanks~~

The board you are using is a Third Party board or it is manufactured by your own company?

Hello @Adolfo_S_Intel
The board is made by ourselves .We confirm that we don't define this address.
So we want to know if this address may exist in C3708?
Thanks~~

Hello, @Jing1127 ,
Do you see the device in the /sys/bus/i2c/devices/ if so, as suggested by this article: https://www.kernel.org/doc/html/latest/i2c/i2c-sysfs.html it might be possible that the device folder has a name file or information about the type of device.
Also can you confirm what do you see with the commands:
i2cget -y -f 0 or i2cget -y -f 1
Best Regards,

Hello @Adolfo_S_Intel
Sorry for replying so late.
I use the command # ls /sys/bus/i2c/devices/,and it show as below.
I try some command and found as below.
Is that 0x08 is address of LNXCPU or device in C3708?
Also I try the command i2cget -y -f 0 as below.
But it seems like 0x08 is not exists.
Thanks~~

Hello, @Jing1127 ,
Can you show me the contents of /sys/bus/i2cdevices/i2c-0/?
What do you see on the LNXCPU:08 folder and what do you see on the device:08 folder?
I would suggest you also consult within the Linux community.
