Hello !
I'm considering using linux on my nspire.
What do you think of the idea of running a pdf reader on it ?
Would it be usable ?

Thank you for your work ! It's really interesting to be able to run linux on the nspire.

Why not? The only question would be where to store them.
But that's no problem if you want to have to use an usb drive the whole time.

Are you saying that an usb drive isn't necessary to run X+xpdf ?
I came to understand that the usb drive was necessary to run X. Was I wrong ?
I only want to have Linux+X+Xpdf+ about 20Mo of PDFs ...

I wondering if it would be okay to solder and usb drive inside the nspire ...

Yes, I think so.
Xpdf seems to be the right application to port.

When you say port ... you say compiling right ? Nothing hard or too long ?
I'm running out of time on this matter ...

But sadly theres no real lightweight alternative (couldn't find some by quick search) :-/

Nope, it can be as quick as typing CC=arm-none-eabi-gcc make && make install if you're using linux

Sorry in advance for being an absolute noob....
how do you run X?

Usually `startx`, if the tool exists.

apparently it doesn't

Hello.
I would like to confirm that I understand well the usb support matter ...

1) I plug the usb while in the Nspire OS then boot linux => the nspire is the host and will keep the host status until I reboot it.
2) I plug the usb after booting linux => the nspire is the device and the usb (computer ?) is the host. I can't use an usb key in this mode.
3) I use the cx_usb_otg kernel parameter and the host/device status of the nspire depend of the cable I'm using (if it is an OTG cable the calc will be a host and if it a normal cable the calc will be a device).

Is it right ?

Okay, thank you
The lack of the otg feature isn't a problem for me.

And, by the way, you confirm me that my usb key isn't detected because I have done something wrong when soldering my miniUSB <=> USB cable ...

Sorry, I don't understand your edited answer ...
- If I use OTG, the calc mode will be device if I use a 4-pin mini-usb cable or host if I use a 5-pin (with a bridge between pin 5 and pin 4) mini-usb cable. And the mode can be switched without rebooting the calc.
- If I don't use OTG, the usb mode will follow that rule (and will not follow the "cable rule") :

USB support is mostly working. The only thing missing is a USB PHY driver. The USB controller driver is currently unable to switch seamlessly between USB host and USB device mode because of this. Unfortunately, nothing much is known about the USB PHY.
That's probably the same reason why sometimes USB devices aren't recognised in USB host mode - the USB PHY hasn't changed the USB hardware to host mode.
To work around this, we get the Nspire OS to set the right modes in the USB PHY before booting Linux.
For USB Host mode: insert a USB OTG cable's A end or a USB device into the calculator while still inside the Nspire OS before running the bootloader.
For USB Device mode: connect the Nspire to a computer while in Nspire OS before running the bootloader.

Or there is something that I don't understand ?

I don't see why It should work with a type A instead of a type B when TI uses type B connectors ...
I'm not even sure that we can use a type A male connector with a type B female connector ...
I think that the parameter is "cx_usb_otg" because it's written on hackspire

edit :
Okayyyy
It's written usb type A in my quotation !!!
There is definitively something that I don't understand  

edit n°2 :
So, if I understand well, it is not possible to use an usb key without an OTG usb cable ?!?
If I put a 4 pin mini-usb cable, nothing happens to the usb PHY who keeps is previous state which is device mode ... It makes me very unhappy  
But I still don't see why I have to use a type A usb instead of a type B usb ...
