On a linux pc, run the following:
Code: [Select]
mount -t ext2 -o loop initrd.tns /mnt
cd /mnt/etc
vi inittab
cd /
umount /mnt

I've done it and commented the line.

The error does not show up anymore :).

But now, I have new problems, like linux asking me to login again and again after a few seconds/minutes, and I can only type a few characters like + or enter.
Also, why is home mapped as ctrl and not the "ctrl" key?

Wrong keyboard mapping...? I think you don't have a CAS CX...

can someone tell me how to connect an usb drive to linux on my nspire cx?

You can buy a OTG USB cable with a mini USB 5-pin A connector on one side and ot the other side there should be female USB plug.

Or, if you are impatient and if you can solder: (my selfmade solution) You desolder a double-USB-plug from an old mainboard and connect all 8 pins in a way that you get 4 parallel connections. That was the hardest part. Then plug in the end of a mini USB A connector (you can use the cable which came came with your CAS for exchanging data between two calcs; plug in the thicker end which says 'A' and leave the other end unconnected) and start linucx. While linucx running, deconnect the mini USB A cable and connect the standart cable (I mean the cable which you can connect to your CAS and to your PC) plug it in the CAS and the 'adapter' which you soldered before. The other port of your 'adapter' should get connected to a powered USB hub and then you can connect all your devices to your hub.
If you are booting from a USB stick you maybe should increase the rootdelay.

Try to use
Code: [Select]
cmdline root=/dev/ram init=/bin/bashnow you should be able to run commands without being thrown out.

I don't. I have a CAS Clickpad.

Try to use
Code: [Select]
cmdline root=/dev/ram init=/bin/bashnow you should be able to run commands without being thrown out.

About the ctrl key, during different boots, I got home being ctrl, ctrl being ctrl (after pressing "del") and sometimes none of them being ctrl.

Also, the "del" key seems to be the main problem. If I press it, the keyboard map goes wild and I still get kicked out quickly. Otherwise, It's working quite fine.

PS: tried again making sure I do not press "del". Home seems to be the "begin", "page up" or whichever key which goes back to the beginning, ctrl apparently does nothing, and "maj" works only one way. I long as I press it, everything is in CAPS and pressing it again makes nothing.
PSĀ²: there are a lot other odd mapped keys as well

I solderd a cable but i don't get the usb to work it connects but i don't know how to boot it :s

I also had strange behaviours although never the exact same one with the latest two kernels (I was using the ones from 23/12 before).

Also, this time, pressing home showed me a screen with some information, and I spotted "Failed to execute /bin/bash. Attempting defaults...."

That's just a warning, no prob at all.
Do you get a shell?
If not, try console=tty0

I did get a shell (already had console=tty0 ), but with the crazy keyboard, meaning I could only type a few characters like * or +.

I've been thinking again...
It looks like "clear" is in fact the ctrl key, but like "maj", you can't disable it (thats why the keyboard acted strangly).
But in this case, * and + cannot be typed.

So, I rebooted and waited a little. This time, the keyboard was strange in the other way, only a few keys like * or + worked.

Would this run on an Nspire running Linux?
