Hello,

1 . when I build the live USB using “unetbootin-window” tools.

If I use ISO file “ kubuntu-elphel-3.iso” dowloaded from http://community.elphel.com/files/live-dvd/   it’s OK .

But if I use ISO file “kubuntu-elphel-4.iso”  to create liveUSB, it will notify a message when booting “invalid or crashed kernel”.

Can I use kubuntu-elphel-3.iso to build software without any problems?
If I want to use kubunto-elphel-4.iso to build liveUSB ,how to fix this problem. 
Do not have Windows at hand to test unetbootin. But just tried creating a live USB in kubuntu 11.10 with both: its built-in usb creator and unetbootin - it works.

You could try another program or burn the ISO image on a DVD disk.
At the same time you should not have any troubles with building software in kubuntu-elphel-3.iso.



2. in kubuntu-10.04 LTS environment built from kubuntu-elphel-3.iso

I can’t upgrade firmware using “search elphel camera” and “net Flash” either.



I noticed that is because the driver for on-board ethernet not installed

(I can asccess internet on win7, the same PC, it prove that the hardware is OK)

in terminal console, if I type “ifconfig” I can see only loopback interface, there was no eth0 interface. If I type lspci command I can see it can recognize the ethernet from “atheros” (it display atheros AR8151 on window)


I dowloaded the driver for onboard called “AR81Family-linux-v1.0.1.14.tar”

I did as follow:

tar -xzvf AR81Family-Linux-v1.0.1.9.tar.gz

cd scr

sudo su

make install

modprobe atl1e

exit

but still canot install driver ,it say “there are no kernel source”

I search google they said I need :

sudo apt-get install linux-headers-generic

sudo apt-get install build-essential

then I type : sudo apt-get install build-essential , it said something like “already install” .

but when I type : sudo apt-get install linux-headers-generic ,

it said something like “connecting to ubuntu server…”

actually, I’m trying to install ethernet driver -> I could not access internet to get update.



My question: could you show me how to install ethernet driver without connecting internet? If I can not install driver for onboard ethernet I can not upgrade firmware!

So, typing in terminal:
ifconfig eth0 192.168.0.15should be reporting: "No such device"

I cannot help you with installing linux drivers on you PC because I can't reproduce the problem. Could you try it on another PC.

Also, there's a way to update camera firmware from the camera, you will need:
1. new firmware image2. NFS (Network File System) server installed on PC
Then if you go http://<camera-ip> -> System Preferences -> Firmware - that page checks if NFS is available, contains a valid image and does an update.
A folder name example for image files:
/nfs/latest80/ Best regards,
