Hi @cobalt

is it possible to update the OS of the kArmTI (or the Android emulator nspiroid) directly with the *.tcc-file?

Why would you want to do that, in the first place?

In the kArmTI-Menü "Link" there's the option "Send OS Update" which let's me choose a file.
But if I choose the *.tcc-file ist says "transfer failed. check the connection and try again". So this doens't seem to be a function to update the OS?

That kArmTI-Menu "Link" option "Send OS Update", is there only to send 'special files' like, for eg. to install the previous version of ndless (outdated by now), eg,
for ndless-v3.1-beta-r557, you can get the following from its  'How to Install':
-----------
Locate the file ‘ndless_installer-.tno|tnc|tco|tcc‘ in the ‘calcbin/‘ directory of Ndless which matches your device type:
    * .tno: classic TI-Nspire
    * .tnc: classic TI-Nspire CAS
    * .tco: TI-Nspire CX
    * .tcc: TI-Nspire CX CAS
Send this file as an OS upgrade to the calculator.
------------------------
Please take note of a few things:
1. the OS update must match the version of the OS you have installed in kArmTI, eg for CX CAS the update file has to have the .tcc extension.
2. that OS update file, needs to be a specially prepared OS update file.
3. before you use that menu option you need to ensure that the USB link is in a 'connected state', ie, by using Menu 'Link->USB Link Connect' before hand.

As a final remark, I would only add that the easiest way to upgrade the OS file that kArmTI is using, is simply to download that new OS version from TI's download site or from TI-Planet and proceed as you would when preparing a new flash file to run on kArmTI (or Nspiroid for that matter). I've written a few notes (pdf's) on how to get you started with kArmTI, whose links you can still find in the topic's first page.

I hope this helps you with your doubts.
Have a nice day.

@cobalt: Hi again,

I might have some good news for you. If you are curious about OS 4.2 you can try it out on kArmTI (I'd recommend v1.81).
The only thing you need is your old Boot1cx.img (v3.0.0.99) which is good to boot OS4.2.

Please try the following method:

1. From TI download this file : TI_NspireCXCAS_4.2.0.532.tcc
2. Make a copy of it and rename the copy to TI_NspireCXCAS_4.2.0.532.zip
3. Open up the zip archive and extract the file boot2.img, (i.e., simply drag it out from the zip archive).
4. (Optional) Rename boot2.img to Boot2cx.img.
5. You may now throw away TI_NspireCXCAS_4.2.0.532.zip

Now we have all you need (i.e., the needed files) to have a go around the new OS4.2 on kArmTI v1.81, namely : Boot1cx.img, Boot2cx.img and the TI_NspireCXCAS_4.2.0.532.tcc.

Have a look at this post: https://www.omnimaga.org/ti-nspire-projects/karmti-ti-nspire-emulator-with-skin-16585/msg403896/?PHPSESSID=vjq7ejsjqc2bsgq0e9smakmc32#msg403896
and check the boot picture, it may help you further.

So far (little free time, ATM), I've only tested kArmTI v1.81 running OS4.2 on windows 7 and apparently it runs just fine.

Good luck with your TI OS4.2 explorations.

@SpiroH: Great! Thanks for your help. I succeded to install 4.2 on kArmTI 1.80. So far I've just tried the 3D-Graphing which works fine.

Good, I'm glad you succeeded. You're welcome!

The latest kArmTI 1.81 crashes on my Windows 7 immediately after starting. The Calculator Interface appears only for a split second and disappears immediately, even after creating a new flash file with kArmTi 1.80 and it's running OS 4.2 and renaming the *.bin into TI_NspireCXCAS_4.2.0.532_N128.bin like you did in the screenshot.
It crashed also with the old boot2.img and old OS when I tried it last week.

Hmm, that's weird, it has never happened on my window 7 system.

Suggestion: Please try to delete this registry key  HKEY_CURRENT_USER\Software\ScrapLab\kArmTI_x86_v1.81 and try again. It should work with a clean registry key, if not please report it back again.

My passion is to help EVERYONE readily “get” and have confidence in their ability to do math.

Using TInspire CAS as a Tool enables students struggling with math to succeed; hard working students to shine; and gifted students to increase their understanding and problem solving skills.

Attached you will find the MyDocument.zip file that contains a complete set of ‘tns’ files for my Kindle eBook, TInspire Guide Algebra Fundamentals, and the addendum I wrote for my Graphing Calculator Tutorial, published by Cengage. Hope that using the emulators and TI handheld you find the files and associated libraries useful.

Use the following three steps to maximize your use of TInspire CAS as a tool. See the versatility of SpiroH’s emulators in steps 2 and 3 by how they deliver the wide range of files and libraries found in the included MyDocument.zip file.

• Access the tool anywhere. SpiroH’s nspiroid and karmTI emulators allows Android tablets, Android phones, and additional Windows options to be used. SpiroH’s nspiroid emulator for Android devices is discussed in a different thread.
• Step-by-step traditional and TInspire solutions. Use the Kindle’s TInspire Guide Algebra Fundamentals eBook and/or accompanying YouTube videos on your phone, tablet, and Windows /Mac /Chromebook computer to fill the gap between traditional and automated solutions. Free two chapter sample of the Guide and the complete set of the Guide’s YouTube videos can be found at ComputerLearningService website. All the Guide’s files and libraries are included in the MyDocument.zip file.
• Practice, Practice, Practice. Use the MyDocuments.zip BCAddendum TInspire ‘tns’ chapter files and MyDocuments.zip MyLib library files to assist you with a review of algebra and Finite Math instruction (Finite Math instruction being Algebra and Statistic applications). The BCAddendum is based on the Interactive Skill Builder CD Graphing Calculator Tutorial for Tan’s series of textbooks for the Management, Life, and Social Sciences. Study these problems and their solutions to see how to use CAS as a tool in assisting with traditional manual solutions.

BCAddendum files for the TInspire were built to be self-contained so they can be referenced anywhere at any time on any TInspire CAS device or emulator without needing the CD or its textbook.

4. Windows 10
   I do not own any Windows 10 machine, so no tests were made.

Works well...
Thank you for your release...

... checking from time to time to see how this very nice application evolves.....

Vogtinator has implemented in Firebird v.0.30 "Suspend and resume to/from snapshot files, the feature I had requested here some time ago. Now you don't have to wait for the calc to boot, it's instantly available."

It works quite well and I was wondering if you would port the implementation on kArmTI.
You UI is very nice and usable, but with the suspend/resume, Firebird is not much more convenient to use despite the more primitive interface.

Hi gchiozzi!

Welcome to Omnimaga. Sorry for the late reply and thanks for the kind words about kArmTI.

...
But is there a way to exit the emulator in "stand by" mode, like when I just switch off the real calculator, so that when I switch it on again everything is back, including the status of the scratchpad?
...

Well, i'm afraid not. However, as a work-around, you can always minimize kArmTI on the taskbar and later restore it, pressing again the on key. Then it should restore all previous contents. If not try to switch it off (ctrl+on) before minimizing it. It's not quite the same, i know, but maybe it helps.

Dear SpiroH
I'm using Firebird (https://www.omnimaga.org/ti-nspire-projects/new-ti-nspire-emulator/), can use touchpad on it.

Good day. You will forgive me for my bad English, it is not my native language, but be something. I am new to the forum and I am looking for your help to try to install this emulator KArmTI to my pc, whose characteristics are:

System Type: x64-based PC

OS Name Microsoft Windows 10 Pro

Intel (R) Core (TM) i5-4570 CPU @ 3.20GHz, 3201 MHz, 4 main processors, 4 logical processors

I already followed the steps indicated by the user SpiroH, but unfortunately I can not execute the KArmTI.
Here are the files you download trying to run the program:

TI_NspireCXCAS_4.2.0.532
KArmTI_v1.81
Boot2cx.img --- size of 1288 kb
Boot1cx.img --- 512 kb size

Please, I require your valuable collaboration to be able to execute the KArmTI, if you could help me with a much more detailed tutorial I would be very grateful. Thank you and stay tuned.

@khiconmtv: You are free to use whatever you like, OFC, no problem!
Sorry, I'm pretty busy now with other (mostly professional) stuff.

Apparently it was already able to run  kArmTI and the emulator works correctly. But now I would like to know if there is any way to activate the touch pad, to handle the calculator with the cursor. thank you very much.
