As seen on datalight website, flashFX doesn't seem useful on the nspire. Flash managing? I don't understand what that means. The Flash Filesystem may be the one thing used, it provides the wear leveling and file management. JFFS2 should have been great, but it's silly to expect such things from TI. --[[User:Squalyl|squalyl]] 11:40, 7 August 2007 (CEST) | As seen on datalight website, flashFX doesn't seem useful on the nspire.

OS update
Silly question, but what happen if during an OS update one (or all) battery is removed ? I don't think even what can say TI that downgrade should be impossible. On TI-68k is "theorically" impossible too --Godzil 10:10, 6 August 2007 (CEST)
- Good point. According to bloo (I haven't tried yet to flash it myself), the whole OS is received before it is written to flash memory, so this greatly limits the risk there was with TI-68k. But still, the write may take a few seconds. If the update process was well built, the new version could be written safely next to the current one, then the old version would be deleted. The boot should be able to start the first non corrupted copy. I will probably try your idea to see, it may be dangerous but we need to take the risk (and the warranty is there anyway).

- I tried, Operating System#Upgrading_the_OS contains the description of the behavior (there is a recovery mode, similar to TI-68k boot menu). But this doesn't tell us if it could be used to bypass the downgrade protection as long as there is only one version of the OS available. --ExtendeD 23:46, 6 August 2007 (CEST)
hmm, theoretically impossible. If it gets a new OS, then it is pulled, couldn't we just put an older OS on there when it asked for an OS reinstall?
- As I mentioned above we can't test without at least two OS versions. The version of the last OS installed could also be stored in certificate memory (or the TI-Nspire equivalent) to prevent this. --ExtendeD 09:46, 7 August 2007 (CEST)
3rd party components
As seen on datalight website, flashFX doesn't seem useful on the nspire. Flash managing? I don't understand what that means. The Flash Filesystem may be the one thing used, it provides the wear leveling and file management. JFFS2 should have been great, but it's silly to expect such things from TI. --squalyl 11:40, 7 August 2007 (CEST)
- Unfortunately you are wrong this time ;) Here is what I have just come across: After extensive research, Texas Instruments found the combination of Datalight FlashFX® Pro intelligent flash manager and Reliance™ fault-tolerant embedded file system, to be the right choice for their TI-Nspire family. --ExtendeD 14:27, 7 August 2007 (CEST)
