No errors appear in dmesg log on my pc...

But a line 'quiet_error: 36 callbacks suppressed'

Is it possible that some sticks have a buggy firmware and create lots of "XactErr" errors?
And sometimes it says the port is reset by eheci-platform....

I first thought, this would be a connection problem of my selfmade USB power-thing, but with another stick it works well.

Ahhh I understand. :D

And how can I tell linux to use a partition as swap, maybe adding 'swap=/dev/sda2' to cmdline options in the bootscript?

I changed nothing with my bootscript...

'No partition table' means when formatting the stick, yuo can chose GUID, MBR, Apple, and nothing. I used nothing.

Ok, now it works... Just tried copying it with dd from an older root fs which had a .ext2 ending.

What was wrong withe way I created my oler root fs before?
-Ereased everything
-Created none/a GUID/a MBR partition table
-Created a ext4 partition
-Copied the data from Vogtinators archive on this partition


Edit: everything is fine. I tried it without partition table, now running.
I think I was too tired yesterday...

I did all this already...

Cable is plugged in while still in OS mode, then booting the kernel via ll2 script (the rootdelay is set to 10). I plug my stick in when message appears and then it recognizes my hub and the stick as sda.
After serveral seconds I get the kernel panic.

I can't even mount the stick when I boot the kernel with an initrd and then plug my stick in and type 'mount /dev/sda' or something like this.

Is there a special extension you need for the usb drive? like ext*, MS-DOS or something else?

with a unix system, just copy it with dd on the drive, tripple-check your spelling, otherwise all your data will get destroyed.
the dd command formats it in the right format, I think ext2 in this case.

edit: sorry, this is just possible if the file has a .ext2 ending. othwerwise just format your stick with ext4 (or any other ext*) and copy all the data in the folder . in ther archive on the stick.

What must I write to tell linux to use a partition of my stick as swap? (it is formatted as swap)

ps: my usb power supply is finished (the circuit part). It works quite good, I just have to buy more powerful batteries (~500mAh). I can even connect my little USB HDD, one without external power supply, all power is given by the USB, in my case my circuit. I will publish pictures soon. The HDD eats up to 0.6A.


OMG: If I get a kernel panic beacuse it can't find my root fs on my stick, after a couple of minutes some text output about EHCI controllers is running over the screen until i hard reset my calc... I thought, a kernel panic would total crash the kernel and nothing will happen anymore?

Just tried my first attempts with USB booting, fails with kernel paic about no root fs... Any ideas?
-Stick properly formatted and data on it
-right files used (vogtinator's)
-Stick is recognized (as sda)

And I thought, the patch would be in the new linuxloader...

kernel /linux/zImage.tns and it tells me that the kernel does not exist or is empty

kernel linux/zimage.tns

(no slash before linux)

My idea behind the multi-touch question was that we could make a virtual screen in the X server that is bigger than the actual screen, and we could scroll in this virtual screen with a special gesture or when we click the pad and move or something like that. So we don't have to use mini scroll bars on the sides.

And somewhere in the web I saw a resitive touchpad witch could regocnize up to five fingers and different pressure...
But not five independent positions? My old laptop with resistive touchpad could determine the count of fingers I was pressing with (Scrolling, rightclick). Gestures like zooming weren't possible.
I am not sure, it could also have been another type of touchscreen...

I found a video where a touchpanel can recognize more fingers:


We should get back to our main topic....

Wrong :P Only capacitive and optical touchsensitive interfaces are capable of recognizing more than one position.
Ouch. But I thought of the right type... ;)

Is that possible under linux where not the standart driver from the OS is used?
Nope, only position, velocity and proximity can be read.
http://hackspire.unsads.com/wiki/index.php/Keypads#Touchpad_I.C2.B2C
So this is limited by the firmware in the touchpad itself?

As the Touchpad is a resistive one, it should recognize more than one contact with finders...

Yeah cool.
We could make a lie detector...
No, a built-in cheat detector during exams :-P

Bad idea. ;)

edit: What, if we overwrite everything in memory what is not used by linux, will the OS (which should be not there then anymore) still protect the LED from flashing?

I just measured the outputs and inputs of some GPIOs connected to the pins on the bottom port, and it's correct.
They're even sensitive for fingertips..

Yeah cool.
