IPhone6 I2C2 bus is not working properly
First we power our phones
Then the probe of the oscilloscope is connected to the test point of I2C2 SCL and SDA
Press start button
At this point, we can see that the current state is very different from the abnormal state of I2C0 and I2C1
The working current of the mobile phone is close to the starting current
The oscilloscope has no waveform
At this point the phone is not switched on
And then we connect the phone to iTunes
Get the reader firmware
We'll see a 4005 error message
