The 1st step into CAS+ flashing
« on: March 17, 2011, 02:58:43 pm »
After being silent for more than 4 years as if they were under NDA, less than a hour ago a TI-Nspire CAS+ "talked" for the 1st time in the World!

Next step: flashing a production TI-Nspire CAS boot2.

I really think the BOOT2 will not work, especially considering this "OMAP5912" business. The hardware is compmletely different between OMAPs and the Zevio... (and TI-Nspire CAS+ probably is an OMAP - I found an unused function in boot1 that appears to be left over from OMAP)

Don't worry Goplat: I have something like 10 TI-Nspire CAS+ with either OS 1.0.554 either OS 1.0.526.

I can brick some of them by trying to flash a Boot2, an OS, or a diags through RS232.
(but I'm pretty sure a newer production OS won't work without flashing a newer production Boot2, as the OS is not located at the same place in the filesystem).

Basically, the debug interface has finally been unlocked, and now what used to be only seen in the emulator is now seen directly from the hardware! ;) Flashing refers to rewriting the whole OS (and potentially the BOOT2), allowing us to use the *entire* hardware! :D

(I might be wrong - please correct me if that is the case.)

The debug interface had allready been unlocked (check HackSpire), but never on a TI-Nspire CAS+ to my knowledge.

As far as I know, this only lets you reflash:
- the OS
- the boot2
- the diags software

It seems boot1 can be reflashed, but only through the diags software.

critor,
Try the key sequence to bring up the diags menu.
You indicated nothing happened  on another post, and you had to reboot.
Does this bring up the Datalight shell ?

No... The calculator just does not turn on and I have to remove the batteries.
Note according to the above log, there is no valid diags image on this CAS+.


But, I've managed to get the boot log of 2 rare older CAS+ prototypes (loan from DataMath.org).

You should have a look as it could help us to understand more on the CAS+, and to dump them some day.

Datalight Command Shell for Nucleus

A:�‘¤œ‘̘">

This one seems much different.
It's running the antic OS 1.0.1.0.334T built on May 1 2006.

* Note the OS seems to be unpacked at each boot.

* Note there is no DHCP messages this time. I cannot exchange data through USB, neither with the Computer Link 1.0 (it doesn't find the calculator, and the network CAS+ interface is failing getting an IP), neither with other CAS+ calculators (no error message, the "Send" menu item seems to be "fake"...)

* Strangely, a phoenix directory is mentionned, although it is not visible on later CAS+ which are only listing the following folders:
/
/phx
/phx/documents
/phx/tmp

* Where is the OS? There's nothing in the above folders (except /phx/documents), but the file system capacity is 27.8Mb, and more than 5Mb are used...
- Hidden directories?
- Something related to the bad blocks reported in previous logs?

* At the end of this last boot, Datalight shell is mentionned, and I'm getting something which could look like a prompt, although I'm in the (very buggy) OS, and although I didn't press any special key.


Goplat, Bsl, everybody... At this point, your guess can be as good as mine.
We might succeed at flashing/dumping, but it will be together.

Thanks for reading.

Does the really old one allow you to enter commands into the command shell via RS232? It would be so awesome if it let you dump that OS to RS232 with "TYPE /phoenix/install/TI-Nspire.tnc" (or wherever it's located on the CAS+... some exploration using the DIR command might be necessary)

critor,
Try this:
As the system is rebooting enter "+++" and return
This is the Hayes modem control sequence to break into command mode , which
hopefully is the shell .
If this does'nt work I will work offline with you on this.
Before there was high speed Internet, there were the days of RS232 and modem commands.
There is a key sequence to break into x-modem file transfer , but its been a while since I have done this.
Look for "modem control sequences" online to learn more.

I can enter commands on my oldest CAS+.
Tried "dir", "ls" and things like that, but only got things like:

Code: [Select]
A:Ôœ‘dœ‘—">01 00:00:50.000 0 | Initializing xmlrpc library


A:Ôœ‘dœ‘—">

A:Ôœ‘dœ‘—">
Command not found!

A:Ôœ‘dœ‘—">
Command not found!

A:Ôœ‘dœ‘—">
Command not found!

A:Ôœ‘dœ‘—">

Error = -1

A:Ôœ‘dœ‘—">

Error = -1

A:Ôœ‘dœ‘—">

What should I type?

Looks promising, at least! You can type "?" or "help" for a list of commands. Maybe the current directory name has gotten corrupted (explaining the weird prompt), so try "cd A:\" to fix that.

"dir" command isn't showing anything interesting in the A: drive.
Moreover, there seems to be some problem with the folder names encoding...

But I can access a "c:" drive:

There are interesting folders, but nothing inside apparently...

(sorry for double-posting)

No there are things in the folders.
They're just hidden.

Have a look:
Code: [Select]
C:\phoenix\>

C:\phoenix\install\>

1980-01-01 00:00:00     <Dir> .
1980-01-01 00:00:00     <Dir> ..
1980-01-01 00:00:00    639280 devfiletree.zip
1980-01-01 00:00:00        17 manifest

Free Space: 18773504 bytes


C:\phoenix\install\>

I don't think it's big enough to be the OS though.


Unfortunately, "?" or "help" aren't triggering anything (unknown commands).
