Maybe I'm testing too much?
Now I'm worrying about my reset-button and flash..
Oh, now I remember what we have to support, too:
Charging the battery while running linux!
It doesn't work yet.

Did it happen to you, too?
If not, my device really hates me (even the reset-button doesn't work always)

Yeah, you should fix that  I don't know how, maybe don't map it at all?

My bad luck proves you right.. I just had to test the NAND again -.- At least it took longer

Hmmm. I see. In that case, move the disable from classic.c to common.c. You put "/* Renable bus access to everything in case the OS disabled them */" there already. I just changed "0" to "1<<7". Maybe it doesn't work and I was just lucky the last few times?

But it works!  At least there weren't any problems after 1<<7.

But one problem does still exist: Edit: After reboot in linux the touchpad doesn't work anymore with nucleus, you have to reboot.
But it doesn't boot anymore and you have to run NAND-Tests everytime you reboot in linux.
I'll try disabling access with 1<<7 to 0x900B0018
With 1<<7 it doesn't damage the flash anymore, but the touchpad does still work only after a reboot. I don't think the touchpad problem is too easy to find, but the flash problem has to be solved asap! I didn't lose my data yet, but why is linux doing something with the NAND at all?

Though, some one did ask about it in a mailing list in 2008 and probably succeeded in writing one. I read: It sounds like it isn't 'NAND' at all, as far as you're concerned. It's
a disk drive of some form. Usually these things present themselves as
IDE, so you'd use the IDE driver. If it has its own 'special' interface
then you probably want a dedicated block driver for it; nothing to do
with the MTD subsystem at all.WTF? Flash controller with IDE interface for ARM SoCs?

Vogtinator, you have royally screwed your desktop. You extracted an ARM linux install on top of your x86 linux root. You're lucky that it still boots, likely thanks to various configuration differences between the two. Nope, it didn't boot. Had to restore the files from another laptop: "export list=`tar -tf xconfig.tar.bz2`; for i in $list; do echo $i; rm /mnt/$i; rsync -lptgoDvzP /media/$i /mnt/$i; done;" The NAND chip itself is supported and always has been. But the NAND controller isn't Is it the same on all nspires? Nice, I look forward to seeing it Here you go:

Look what I found out: http://www.linux-mtd.infradead.org/nand-data/nanddata.htmlThe NAND is already actually supported by linux! I was a bit frustrated because of this silly synaptics_i2c polling too slow, so I did a bit of research. Edit: After reboot in linux the touchpad doesn't work anymore with nucleus, you have to reboot. But it doesn't boot anymore and you have to run NAND-Tests everytime you reboot in linux. I'll try disabling access with 1<<7 to 0x900B0018 Edit2: The TOUCHPAD WORKS! I'll upload a video later/tomorrow

Partitioning would be great, but maybe the size of the flash is hardcoded? BTW: Buildroot builds are working now. I downloaded one, ran "tar -xvf xconfig.tar.bz2 -C ." and was surprised, MY PWD WAS "/"  Yeah, I've overridden my opensuse installation. Now an arm system was (not) running on my laptop. After 5 hours playing with backups, I now have a booting system without audio Why does this *** tar overwrite my files? The touchpad works, but it's lagging a bit and too slow, I'll continue with my work after my system is fine again

I'll get cracking on the hardest device then - the NAND. Yay! But we don't have any filesystem driver for it.. But the driver shouldn't be TOO hard, the emulator source should be enough, maybe there's already a driver for our chip available?

If you're using an initrd (which needs decompression as well), it doesn't make any difference. I'd say XZ, but do we really have to discuss about 0.5 MB (the kernel won't be much larger in the future)? lso, in other news, I2C is working on all touchpad platforms. Now we just need a driver for the touchpad. Just a heads up, since we're using the I2C bus now, we should define a I2C driver instead of a platform driver. Can I do it? I already have most of the code as you already know

Great!
I hope I have some time this weekend to continue working on a touchpad driver, was pretty busy last week.
Serial debugging is really good for that, the screen is way to small to read tons of lines of debugging messages..

It's up to the mainstream and the businesses. Whatever works best for them. No, people want to continue using software they're already used to. Best example: All I can tell you is that I run win8, and I use it exactly the same as win7.
