Used windows to run putty after installing drivers.
Ran, configured => Nothing shows on the console.
The screen still shows the same "Please wait" screen.
Could this be because the device is in recovery mode? (which shows in lsusb)
Is the serial port activated only when the device boots normally? |
The serial port is activated when the boot code burned into the SoC is executed - then it is never turned off.
It gets passed (or re-used) by each part of the boot process.
First the SoC
Then u-boot
Then the kernel
Note: Linux is a "Unix like" system, it
**will not** run without an operator's console (which is what the serial port is).
Since you only show a diagram, rather than the actual work -
My first suggestion is to re-check your work.
Pay attention to connection problems (or shorts) at the serial port connection pads.
Be sure you have Putty correctly optioned.
(The serial port never changes its speed, that is one thing you need not worry about).
The with the Kindle
powered down <<-- means un-plug battery, the only way to power off a Kindle.
Temporary jumper Tx - Rx on your adapter board, you should see every character you type in Putty echoed onto Putty screen.
If that is so -
And nothing is wrong physically with your connections -
Then the Kindle is not running (after you remove the jumper and re-connect the battery).
