Enable the emulator's capture to file feature.
In (Linux) minicom it is in the configuration panels as "Capture File"
In (Windows) ??? I am not sure, it will depend on the application but should be somewhere - perhaps in configuration - session - logging.
Sorry, knowing what you may be using under Windows would not help me, I would have to look up that application's docs - I don't know windows.
This may give what is required at this point:
- You have communications established over the serial port ;
- You have set up recording the communications to a (capture, log, transcript, whatever) file ;
- Use the: "Hold power switch forever" method of getting the Kindle to do a complete restart ;
- Save the recorded result file ;
- Start another recording file ;
- Repeat the complete restart.
Twice? In two capture files?
Yes.
Because I think the DX is one of the machines which alternates between the two boot image files on the machine with each hard re-start.
The image files look as if they have two (2) complete sets of U-Boot environment and kernel images.
All stored in a device physically different than the device that has your broken system image.
zip or tar/gzip the two files, attach to post.
I expect they will tell me what to either do next or what to ask for next. |
File is attached, just one. Took awhile. I'm on a Mac, OSX 10.8, using secureCRT to capture the session. Using FTDI TTL-232RG-VREG1V8-WE converter. Only one file because the system is in a loop and can only be interrupted at the U-boot point. The file has basically one iteration of the loop. Hope the information is helpful in spite of this.
I have a new problem that just ate up an additional couple of hours. My serial port has gone silent. With no changes to hardware setup, I suddenly have nothing coming out of the DX. Tried on two other computers with same result. Holding down power key seems to have no effect, though with enough random keypressing I have got into a reboot to happen, and even a recovery console once, but on DX screen only, silence from serial port.
To cover the obvious, I have examined my soldering and nothing has changed as far as I can see. Rebooted, tried on different computer, checked drivers, checked sanity. Research tomorrow.
