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?

Yep, it should work out of the box in the next major release 4.1-rc1 onwards.

Wondered how linux on nspire is doing after a year of not looking into it, and just found this.... Awesome!!  :hyper:  :thumbsup:
Hopefully nothing more will prevent Arch Linux from booting then

If anyone wants a kernel build, I can make one when I have time.

If you happen to do so, could you enable cgroups please  :)
(Arch won't boot without it, but I reckon it would be nice on the nspire: Small, clean base to start from, fast package manager, prebuilt rootfs on archlinuxarm.org)

Also thought about doing it, but tangrs github repo is only legacy code. (and frankly I'm short on spare time right now :/ ) Where would you take the code from, linux-next?

Is https://tiplanet.org/nspire-linux-builds/ updated?
I don't think so, at least with dtb version downloaded two days ago usb was still broken.

Yay, progress!
I built a kernel using the fairly old config and modified it a bit so it should work with systemd. Highly untested, might work just fine or ignite your calc.

nspire-linux-builds haven't been updated in a long time, but it's being worked on, there are some minor issues.
Automated builds are planned.

Well, it bootet without any smoke or flames :D Actually without any issues at all

uname -a says 4.0.0-rc6, but tangrs states that his code will land in 4.1-rc1 (accordingly I couldn't get any usb action either). But it's nice to see the calculator running the newest kernel of all my linux devices (plenty)   :3

I'm not sure where tangrs' code is right now, but I guess in linux-next. Not certain how adventureous it is to build from that though

Great, so the config is working for systemd.

Whoops, I cloned the wrong repo. Well, the minor nspire-linux-builds issue is now solved, there will be new builds soon.

It should compile just fine, there are automated tests running. (I know this because my first submission wasn't compatible with a specific arch not defining a macro...)

Yeah, it's sitting around in linux-next at the moment. It will (hopefully) get merged when the next merge window opens.

You can download the patches and apply them manually to your tree. It should apply cleanly to the 3.9 or 4.0rc kernel tree.

Patch #1
Patch #2
Patch #3

http://tiplanet.org/nspire-linux-builds is running again, with linux-next builds and up-to-date buildroot images.

Mhmm.. Has anyone got usb working with the builds from http://tiplanet.org/nspire-linux-builds ?

Uname says 4.0.0-rc7-next-20150410, but my usb thumbkeys won't work for some reason. lsusb ends without any output, no reaction on dmesg and no new device in /dev either.. (doesn't matter whether I connect otg before or after linux  boot)

I can't guarantee that my otg adapter works (a little wonky construction), but it did with the old kernel and when pluggin it in while in Nspire OS it complains properly about a device connected it can't handle

lsmod end with "/proc/modules: No such file or directory"
