Continued from prior post above.
There are two builds of u-boot installed on your device:
A small memory footprint one (which is the first one that runs) -
A large memory footprint one (bist - Built In Self Test).
Since I have to invent these directions as we go (and I don't want to disassemble my PW-3 just to fix yours
) . . . . .
I want a file with everything we can possible learn at this point.
Please do the following:
- Get the setup to the point where you can see the u-boot> prompt.
- Use the 'settings' menu(s) of the terminal emulator (minicom?) to enable a capture file (log file).
- Ensure the 'normal' USB-to-PC cable is disconnected from the Kindle.
- Press and hold the power button on the Kindle for at least 30 seconds.
This will trigger a full POR (Power On Reset) and re-boot.
- When the u-boot> prompt appears again on the terminal emulator, do:
- Enter: help (or just ?)
- Enter: printenv
- Enter: bist
- When the bist prompt appears, do:
- Enter: help (or just ?)
- Enter: printenv
- Use the terminal emulator settings menu(s) to disable the capture (log) file.
- Open the capture file with a plain text editor (gedit, geany, whatever openSUSE provides).
- Search for your device's serial number, replace all except the first 6 characters with XXXXX s.
- Save the modified capture file.
- Enter: gzip whatever-filename-you-used
This will compress the capture file and append a '.gz' to its filename.
- On your next post to this thread, select the 'advanced editor' (quick reply -> go advanced)
- Type whatever might be helpful (we are writing for future lost souls).
- Scroll down, past the text entry box to the 'manage attachments'
- Use the 'manage attachments' to upload the compressed capture file (with the obscured serial number).
- Thanks.
For comparison, here is a list of the bist commands from a very early PW-2:
