Ok, I'm sorry, I wasn't using the old kernel, I probably replaced the old unintentionally. Now USB works perfectly, thanks !


Edit : how to make my rootfs (xconfig) writable ? It is on a USB key, it works, but the partition is readonly.


Edit 2 : If it can help you, output of 'mount' :
rootfs on / type rootfs (rw)
/dev/root on / type ext4 (ro,relatime,size=29488k,nr_inodes=7372,mode=755)

Is it normal to have two things mounted on / ?

Probably your FS got corrupted somehow, run fsck on your desktop to fix it.

I have no idea why it is shown that way, but a directory can only be mountpoint of one device at a time, the newest mount is what you can see in the directory.

How do you install the filesystem into the USB device ? I formatted the partition in ext4, and uncompressed the .tar.xz with root privileges.Is this the right way ?

I don't know actually. I tried various devicetree options, but none of it seem to work as expected. I only tried OTG, though, as the host controller doesn't work reliable with "high speed" and the OTG one can switch to high speed without disconnecting.

Why not ask on one of the kernel mailing lists?

Would it be possible to run Raspbian on the nspire?

If Raspbian is armv5 compatible, yes. But it's probably armv6.

You can, if you want to :P

Yep, it's ARMv6, I thought it was ARMv5. bummer.

Using raspbian makes very little sense. All of its packages are optimized for FPU support, which I don't believe the nspire has. There are ports of debian to armv5 platforms that you could potentially use, though.

Take a look at this page: https://www.debian.org/ports/arm/#about

The Marvell port in particular is ARMv5, and potentially others are as well.

The only real benefit obtained by using debian is the package manager, though, which takes up an impractical amount of space with package caches and such.

I know nothing about kernel dev, either you or tangrs (where is he?) should ask.

Happy new year to everyone :)

I've gotten back into the TI-Nspire scene after a long year of uni and dealing with personal stuff. Currently working on the USB driver and almost getting seamless switching between USB host and gadget working :3

Here :)

You could get Debian or any Linux distro that supports ARM to work on it. Personally, I've succeeded with Debian but I believe Arch Linux should be possible too. Rasbian wouldn't make sense since the TI-Nspire doesn't have hard float support.

Great to see you back :)

Hopefully the USB gets working soon.

Today is a good day :D

The USB OTG and seamless switching support patch has been accepted and will be merged into the next Linux version.

Does this mean USB will work with the latest kernel?
