TI-Bank has newsed about a bug with OS 2.1, which permanently freezes you TI-Nspire basic ClickPad if you've got boot2 1.1.
http://ti.bank.free.fr/index.php?mod=news&ac=commentaires&id=882
If you've owned your calculator for a while and already installed OS 1.4 or newer, you probably have boot2 1.4 and aren't concerned by the problem.
But if you've just bought your calculator, it may come with boot2 1.1...
And when you connect it to your computer, that stupid TI-Nspire Computer Link tells you to install OS 2.1...
Some minutes later, your TI-Nspire is totally useless.
This is a major bug that many Nspire owners most likely ran into since July, when OS 2.1 came out.
-
Let's put the blame where it belongs - this is not a bug in OS 2.1; this is a bug in the old version of BOOT2.
When BOOT2 1.1 has finished loading the OS, it calls the memset function, to clear the memory that was used to hold a copy of the TI-Nspire.cer file. But they mistakenly passed to memset the size of TI-Nspire.img instead. If TI-Nspire.img is greater than approximately 5800000 bytes, then memset ends up trying to write past the end of memory, so it crashes. OS 2.1 is the first OS large enough to make this bug visible.

TI-Bank has finally newsed about the bug with OS 2.1, which permanently freezes you TI-Nspire basic ClickPad if you've got boot2 1.1.

If you've owned your calculator for a while and allready installed OS 1.4 or newer, you probably have boot2 1.4 and aren't concerned by the problem.

This is a major bug, and sadly, no english calculator site has newsed about it.
We were too busy in july taking care of the downgrade protection...
As Omnimaga is one of the most visited english calculator site, I thought you could make a similar news, as it is important to inform current/future Nspire users.
That's really bad. Hopefully, I'm not having that kind of problem.
Will Texas pay you if it crashes your calculator forever?

I believe all TI calcs come with 1 year warranty. Nevertheless, this problem will not completely destroy your calc, it only forces you to send an OS below 2.1 to update boot2 before you can send 2.1.
-
Most likely they would send you a replacement or ask you to send the product in to be repaired. I'm not exactly sure how TI handles damaged products that are under warranty.

So that doesn't happen with the 2.1 CAS because it doesn't have the TI-84+SE ROM and is a little smaller ?
-
I think I'll move this to news section. It's a shame that TI hasn't done anything about this, considering the amount of people who most likely ran into the same problem
And yeah I was a bit busy myself at work so I've been a bit slower on news and I tend to take a few days before noticing some posts.
Has this been reported to TI-(doesn't)CARES, btw?
(Btw I edited the first post a bit so it fits news better and also fixed a spelling error on "already". I hope you don't mind)
-
thanks. I still have boot2 1.1

I am sure that they got a helpful generic bot created answer
-
yep happened to me. apparently i was one of the first to get it. (lucky me :p) http://ourl.ca/7711
-
So, more TI epic fail?
-
I think I actually ran into this, but I just went down to 1.6 I think it was, and all was good afterwards.
-

Interesting.
This also means that the boot2 update is installed by the new OS? This is the worst order.

Yes. The boot2 is updated by the new OS, after the 1st successfull boot.

Correct.
For the curious: The main reason 2.1 is so much larger than 2.01 is that it has support for the Chinese language. (If you scroll all the way down on the languages list, the last two options are simplified (mainland) and traditional (Taiwan) Chinese, respectively.) Chinese has, in general, a different character for each word, so it requires a very large font (853 kB) in case someone wanted to use it in a document:
-
Could TNOC (http://ourl.ca/6632) be modified to fix this problem (remove the Chinese font from 2.1)?
-
That could be possible, that is actually a great idea :D
-
No, it's not a separate file.

Whoah i would like to know how to type chineseon the tinspire, i so want to, and i tried to but it kept typing english
and another bug found out add it to the many flaws that have aklready been discoverd
-

First, you have to choose it as the language (from the home menu, go to "5:Settings & Status" and "1:Change Language..."; it's the last two options)
Press the flag button to toggle between Chinese input on and off. When it's enabled, a "δΈ" symbol appears in the upper-right.
Type in the word you want phonetically (in Pinyin for Simplified Chinese, in Bopomofo for Traditional Chinese), then press the number for the correct character.
-
thanks i just didn't know how to activate it

Wow I see why it's so large... I wish there was a way to get rid of some languages. On the 83+ series, you can get rid of every language app if you want then re-install them later.

Well, serves TI right for releasing an anti-dev OS :P
I wonder what OS 2.2'll be like.
-
Yeah, when I bought my calc at Staples, it had a 1 year warranty. However, for the 2nd year extended warranties, you had to mail it to TI directly. I think now over here you just get one from Staples again or something. It might have changed, though.
As for OS 2.2, the only info I could find is http://tibank.forumactif.com/actualites-f25/infos-futur-os-22-t6083.htm
There were also rumors about a paid SDK somewhere, but I'm not sure how legit they are. Basically, for now it seems like it will mostly be the addition of 3D graphing stuff.
-
Uhh! 3D graphing? That would be very useful. No TI or Casio has that right?
-
The TI-89 does. All of the TI calculators have additional software that can be used for 3D graphing, though. For the 83+ series, Graph3 by Detached Solutions is the best I'm aware of.
-
KermMartian also wrote one and there are about 10 others, but I think the two best are by Detacheds and Kerm.
-
I didn't know... this website is great! I have learned more in a few hours than ever! (about calculators...)
Where's it in the TI-89? I have a friend that has one but doesn't really know how to work it...
-
Glad you like the website! :)
As for 3D graphing, I don't know where is it, though. I never used a TI-89 calculator for maths. ;D
-
Me neither... I use the TI-84+ (to program in class ;)). Are those 3D graph apps for the TI 84 available on TI-Calc?
-
To get to 3D graphing, there's an option under MODE that says Graph Mode. Switch that to 3D, and the y= editor should change to z=.
