Hi NVIDIA

We detected 0x50, 0x56, and 0x58 under I2C1 using i2cdetect in Thor Dev Kit
0x50 is Thor’s internal EEPROM and 0x56 is Dev kit’s EEPROM, may I ask which device’s address is 0x58?

Hello @rain1_wang,

Is it possible to obtain the output of these:

i2cdetect -l
i2cdetect -r -y 1
grep -R "0058" /sys/bus/i2c/devices/ 2>/dev/null

Here you can get some guidance on this tool use: https://developer.ridgerun.com/wiki/index.php?title=How_to_debug_with_i2c-tools

Hi,

Address 0x58 corresponds to the identification Page of the CVM EEPROM.
Address 0x50 and 0x58 access different memory regions of the same physical device.
This is expected behavior.

Thank you,
