Unfortunately, that's the thing. Most of the times when it reboots, I am not even operating the calculator. There have been a few times it reboots when I'm using it, but it's completely random from what I've observed. I will try and attach a video of the rebooting process.

A video of the rebooting itself won't be helpful sadly enough. Does it happen after a "long" time left alone on its own?

It definitely reboots a decent while after I open the application, not necessarily a long time when left alone. Even if I was using the device without idling it, it would still reboot. It's almost as if it reboots after a certain time on average. Unfortunately, that's probably the only description about any triggering steps that I can give. I am trying to understand what else may cause it.

As a follow-up, I looked into a few posts online. I found that in problems regarding crashes, the nspirelogs were asked sometimes. This is the one file that i WAS able to find. Hopefully, it is of some use in being able to identify the error.
Thank you

I'm not used to nspire logs. I can extract instruction addresses from exceptions* files:

Locating where they are in RAM (OS copy or khicas image) may help.
The files with high numbers corresponds to version 5.3 of the OS, the files with low numbers to version 5.2, this suggests that you have downgraded your nspire, probably with backspire, is this correct?
Did you run the lua gui application or the shell interface version of KhiCAS?
I don't know what Data fault status means, it is most of the time 1, a few times 5.

Yes, I did use backspire to downgrade from 5.3 to 5.2. I did so when I saw a KhiCAS version on your website corresponding specifically to 5.2, so I thought it could fix my crashes. Unfortunately, the reboots are still happening with the same frequency... I run the lua application as it seems more user-friendly and is similar to the stock nspire UI as well, allowing me to carry on my calculations in a quicker way.

could you check if the crash happens with the shell version ?

It doesn't seem to happen on the shell version! But the interface does seem like it will take some getting used to. Thanks a lots for your time!

Then it's an interaction crash with the OS GUI, perhaps when the OS tries to enter sleep mode.

There is a learning curve with the shell version, but you can do much more.

Je viens de mettre en ligne un update de KhiCAS pour
