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:
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.
