Hello,
I'm using a Raspberry Pi Zero with a buildroot Linux distribution on it. I have also I2C Hall effect sensor (Si7210) connected to it. It has worked fine so far, but right now each time I connect the sensor board to RPi, I get the following errors while using i2cdetect on my bus:When using the i2cdetect tool with no sensor connected or with a different sensor connected (Si7021 this time)... it works fine though.
Any idea what can be the problem here?
Thanks in advance for any help!
