I have an Adafruit DC Motor hat with a CAT24C32 EEPROM. Product ID: 2348.
I enabled i2c0 in config.txt.The EEPROM is connected to I2C0 and has 3V3 on pin 8.
i2cdetect -y 0 shows no devices (all --).
/proc/device-tree/hat does not exist.
With a logic probe on I2C0 SCL and SDA, the signals look Ok, like the EEPROM datasheet, except always NAK.
Am I doing something wrong?
I enabled i2c0 in config.txt.
Code:
> grep i2c /boot/config.txt dtparam=i2c_arm=ondtparam=i2c_vc=oni2cdetect -y 0 shows no devices (all --).
/proc/device-tree/hat does not exist.
With a logic probe on I2C0 SCL and SDA, the signals look Ok, like the EEPROM datasheet, except always NAK.
Code:
> i2cget 0 0x50 0 bWARNING! This program can confuse your I2C bus, cause data loss and worse!I will read from device file /dev/i2c-0, chip address 0x50, data address0x00, using read byte data.Continue? [Y/n] yError: Read failedStatistics: Posted by tomdean — Wed Feb 25, 2026 5:46 am
