I2C problems

[jlazkano]

Hello,

I try to connect some I2C sensors. Yesterday the MPU 9250 works for some hours, but now I can not get it working. The I2C app say "I2C enabled stoped":



When I disable the I2C interface in the Raspberry Pi setting, I get this in dmesg:

PHP Code:

[  534.089750] OF: overlay: WARNING: memory leak will occur if overlay removed, property: /soc/i2c@7e804000/status

[  537.206176] i2c-bcm2835 3f804000.i2c: i2c transfer timed out 


And this when I enable it again:

Is something wrong with my Raspberry Pi 3B device? How could I start the I2C module?

Kind regards.

Hello,

I burn the OpenPlotter image in a new SD and try to configure the I2C sensor, same result:



Is my Raspberry Pi broken?

Could I debug it deeper?

I will appreciate your help.

Regards.

Hello,

I still have the I2C not running message, but I fixed the MPU sensor detection with this commands:

PHP Code:

sudo systemctl enable openplotter-i2c-read.service
sudo systemctl restart openplotter-i2c-read.service 


Hope this will help to someone else.

Regards.
