[Tuto] [EN/FR] Install/Installer nBoot + ControlX (+Linux)

[GalacticPirate]

Amazing I find that the latest official boot splash is the nicest looking I'll try that as soon as my Nspire is fully charged -- Thank you!

Don't try on real hardware, StarTrekVoyager.

Something's wrong with the emulator, here.

[GalacticPirate]

OK, I'll let you see what's wrong. I wouldn't have installed it immediately anyways

nBoot1 is working with all 4 boot splashes.

nBoot2 is apparently only working with the CX1 and CMEVT boot splashes (which are similar).
Unless I've done something wrong, it must use some values somewhere, which are different with the CX2 and COLOREVT boot splashes...

There's been an initial nBoot release, let's call it nBoot1.
And then an update some days later, let's call it nBoot2.

nBoot1 was outputting garbage on the screen for some seconds during a cold boot.
nBoot2 does fix this.

You may check the differences, here are nBoot1 and nBoot2, packaged with the the CX v1 boot splash :

manuf+graphics_nspirecx1+nboot1.img.tns

manuf+graphics_nspirecx1+nboot2.img.tns

Both images are working on the emulator.

And now, here are nBoot1 and nBoot2, packaged the the CX v2 boot splash :

manuf+graphics_nspirecx2(cr3+)+nboot1.img.tns

Edit : file removed
2nd image doesn't boot on the emulator...

Ok, was some stupid IPS generation error.

I've updated the nBoot manuf images file :
viewtopic.php?f=57&t=18920&p=216699#p216699

Once again, you should confirm it works on emulator first.

And now comes an easy on-calc solution !

Here is an experimental 4.4.1 alpha build of BtMg + nsNandMgr :

nsNandMgr4.4.1alpha.zip

It's supposed to let you reflash your boot splash without corrupting/removing nBoot !

When you try to flash the manuf image you've opened, it prompts you for the type of flash you'd like to perform :

• Extended flash : That's the behaviour that was implemented in previous versions.
  Both SPI and splash zones will be overwritten.
  So you'll get :
  
  • the boot splash of the manuf image you've chosen
  • an nBoot installation if you didn't have nBoot and nBoot was included in the manuf image you've chosen
  • an nBoot update if you did have nBoot and nBoot was included in the manuf image you've chosen
  • an nBoot uninstallation if you did have nBoot and nBoot wasn't included in the manuf image you've chosen
• Basic flash : That's the new behaviour which needs to be tested, on emulator first.
  It will only reflash the splash zone.
  But nBoot does partially overwrite the splash zone setup and data.
  So if you did have nBoot, this option will preserve its alterations to the splash zone.
  Note that it may not work with future nBoot updates...

By downloading any manuf image and performing a basic flash, you should now be able to install any of the 4 official boot splashes known so far without corrupting/destroying nBoot.

is there upgrades for hardware revisions after V?
