I have connected MLX90640 IR sensor to i2c1 bus of Jetson nano. But its not detected most of the times. The detection ratio is like 1 out of 25 times. I have probed the i2c lines while using “i2cdetect -y -r 1” command to detect the MLX90640 device on i2c bus, but i found that SCL is pulling low & not releasing at all.
Initially without any operation on the i2c bus, both SDA & SCL is with 3.3 v.
Any operation on the i2c bus makes the clock signal low & never released.
Added 2.4k pullup resistor on MLX90640. But the issue is still not solved.
Tested some other I2C device (Potentiometer ) on jetson nano & its detected successfully.
Tested MLX90640 on beaglebone & its detected
