I have two problems.
One is that the Kindle 4 will not boot.
The screen is frozen and the computer is disconnected.
I have a serial port connection and this is the log file.
What is the problem?
Another problem is that keyboard input is not available on the serial port.
So I can not get into u-boot.
The current values are tx 3.26v, rx 1.97v.
Why does not keyboard input work?
One is that the Kindle 4 will not boot.
The screen is frozen and the computer is disconnected.
I have a serial port connection and this is the log file.
What is the problem?

Why does not keyboard input work?
