(knowing it's practically impossible to crack the 2048 bits RSA keys to sign third-party OSes)
2048 bits o.0
On topic:
No freaking way! This is so awesome, I don't even have words for it! Really hope this finishes. If only I could help in some way :(

Maybe with ndless USB support we can have a hook up a hard/flashdrive and use that as filesystem?

With a working Linux port, we won't need Ndless' USB support: Linux will be running on bare metal ;)
(assuming the USB controller has a Linux driver, otherwise it will have to be made for this Linux port - in which case, the work on USB support for Ndless would prove useful for reverse-engineering and reimplementing)

We're not there yet, but agreed :)

Well, with 'all due respect for you sir', i wouldn't rely on that. Impossible is nothing remember?
...Maybe with ndless USB support we can have a hook up a hard/flashdrive and use that as filesystem?
Well, he can always try to use a ram disk to install the initial file system: http://lwn.net/Articles/210046/  and more http://www.ibm.com/developerworks/linux/library/l-initrd/index.html
Good luck. ;)

It's unlikely to be possible to 2048-bit RSA keys before two or three decades (if it ever becomes practical), i.e. a complete eternity in the field of computing ;)
Even factoring RSA-1024 is currently pretty much out of the question, though the leading researchers of the field believed in 2009 (when they factored RSA-768) that factoring RSA-1024 could be done by 2020 (but probably no sooner than 2015).

Well maybe TI will share the key with us... sooner or later... but I'm not too sure of that :\

That's a pretty good idea, i'd say. Maybe in the end TI will give up on their OS and just install an open-source os, like Google (well rebranded mind you), and still make a lot of money. Who knows what the future has in store for us? ;)

Even back when they made open-minded calculators (which was the case when I started programming said calculators), they didn't provide the RSA private keys for the OS. Nowadays, where they think that not giving such keys protects their assets for standardized testing, why on earth would they provide the private keys ?
Don't set your hopes anywhere with TI's openness ;)

We're off-topic, though ;)
Back to topic:

* on the "nspire" branch of the nspire-linux repository, I can see the following commit:
Code: [Select]
commit a1c7b431150faccea6866e6ff66ddebbc29b1d3c
Author: Daniel Tang <[email protected]>
Date:   Thu Oct 4 00:59:18 2012 +1000

    working framebuffer

When you have set everything up correctly, we're eager to see a picture ;)

* it's clearly a good thing to make everything built-in, but you should select a single compression type, probably XZ (slowest, but best compression ratio, which is desirable for us because and the amount of available Flash memory is pretty limited, especially on the Clickpad & Touchpad):
Code: [Select]
CONFIG_RD_GZIP=y
CONFIG_RD_BZIP2=y
CONFIG_RD_LZMA=y
CONFIG_RD_XZ=y
CONFIG_RD_LZO=y

CONFIG_ZLIB_INFLATE=y
CONFIG_LZO_DECOMPRESS=y
CONFIG_XZ_DEC=y
CONFIG_XZ_DEC_X86=y
CONFIG_XZ_DEC_POWERPC=y
CONFIG_XZ_DEC_IA64=y
CONFIG_XZ_DEC_ARM=y
CONFIG_XZ_DEC_ARMTHUMB=y
CONFIG_XZ_DEC_SPARC=y
CONFIG_XZ_DEC_BCJ=y
# CONFIG_XZ_DEC_TEST is not set
CONFIG_DECOMPRESS_GZIP=y
CONFIG_DECOMPRESS_BZIP2=y
CONFIG_DECOMPRESS_LZMA=y
CONFIG_DECOMPRESS_XZ=y
CONFIG_DECOMPRESS_LZO=y

Thank you for relaying the info to here Lionel :)

Hat of to Tangrs, for taking the time to work on this.
If this port gets successful (and I have a feeling it will), it will change the entire Nspire scene.

Also, the OS can be "hot-launched" - basically, it can replace the currently running Nspire OS. :)

Great job on this! :D Reminds me that I should be contributing more to the ndless side of things... ;)

I have a busybox ramdisk booting successfully and it dumps me to a shell. Next up, I'll be working on a key pad driver.

sorry about that, but the youtube embedding feature is really picky. you have to use the link obtainable by pressing the share button and selecting long link or it doesn't recognise it.
and that's pretty fantastic =D
