One issue I've run into, is that after a short amount of time, the keypad starts to glitch. Meaning that I have to press a key a few times to get it to be typed, or sometimes it will be entered several times. Any solutions? thanks.

I can confirm that this happens on clickpad calculators. It is often triggered by the clear key for me as far as I can tell. USB keyboards work just fine.

A quick update: the IRQ controller driver for classic models has just been mainlined.

I updated the Hackspire Wiki page at http://hackspire.unsads.com/wiki/index.php/Linux#Newer_device_tree_kernel_status. Is the rest of the page up to date?

Also, can you tell what should be added to the dts files for the entries that say "Should be a matter of adding a few lines to the device tree"?
I am using an Nspire CX, and I finally got the device tree kernel to build and run a few days ago.

The kernel in this video is still the old version (without DTB support, not mainlined),
so you'll have to use one of these builds (expanded) and extract one of the xconfig filesystems onto a usb drive. Run "startx" and it should work.

You can use nlaunch to skip the OS, but as it's a bit more complicated I'd try to get it booting manually first.

You said you have a working kernel, right?
You'll just have to get USB drives working and boot from it: Append "root=/dev/sda" to the  the "kernel" line in your .ll2 file.

You'll need a linux system for this. The partition should be ext4 or ext3 formatted and the .tar.bz should be extracted like this:
Code: [Select]
tar -xvzf xconfig.tar.bz2 -C /media/Replace /media/ with wherever your drive is mounted.

do i need the initrd file in my linux folder on the calculator?
If not, the only files in my foulder should be the linuxloader2.tns, the zImage and the startscript

thats how my bootscript looks like:
(its one from an earlier post)

Code: [Select]
kernel linux/zImage.tns
cmdline root=/dev/sda earlyprintk debug console=tty0 console=ttyAMA0,115200n8 rootdelay=10
boot

is that right or must i change something?
