linuxcnc 2.5 upgrade on 8.04 hardy offline

I'm having trouble getting my 5i25+7i77 pc running. I think i need to install 2.5 on the machine to configure the mesa card but the pc is not online. Been trying the last day & a half to get those files on a usb to upgrade the hardy live installation. I couldn't load wxwigets so the usb software would work. using ubuntu 10.10 on a laptop to get the info but it won't install curl.......which is needed to install widgets and on and on. Ten new steps for every one i take. Is it really this hard to get some info on a usb stick with linux?? please help!

a hardy installation is now not supported , i would take a leap and upgrade to the latest
because sooner or later your going to have to , it may of course mean you need to change hardware or motherboard
as i dont know what your using at the moment .

it would be far better to move the pc to have access to the internet when upgrading or installing
why not install the latest hybrid.iso which has version 2.6.3 , that should install from a usb stick

I need a way to get this pc working with a 5i25+7177. Are you saying that it won't work? I intend to get a new pc soon for all this but i'd really like to see the machine up and running with what i have for now. Just got a usb wireless to see if I can get the pc online. Hopefully that will help. Let me know what you think.

Your existing PC may or may not work depending on whether it works with
a much newer linux version (and can boot from a USB stick or DVD )
You probably will just have to try (back up your config files first)

I don't really understand how the hardy isn't possible. There are instructions on linuxcnc.org for doing exactly what i want to do and a file to do it with. Any suggestions?

Hi

I produced some zips to do just this on a specific small computer some years back.
It would only run 8.04, because it was uni-processor and very limited memory and processor power

They are still on my site

mgware.co.uk/CNC/NCBOX/manual/commands.txt
is the instructions

You haven't actually said what you want to upgrade from, so these are both zips, which allow upgrade from 2.3 to 2.5

mgware.co.uk/CNC/NCBOX/manual/2.3-to-2.4.7-upgrade.tar.gz

mgware.co.uk/CNC/NCBOX/manual/2.4.7-to-2.5-upgrade.tar.gz

I have not used them in a while, but they worked perfectly well last time I tried, you will just need to add the latest 2.5 version, when I did this it was 2.5.2 I think.

regards

we are not saying it's not possible , what we are saying is 8.04 hardy is essentially end of life from 2.6 onwards , so just beware that to be up to date with linuxcnc and have some of the newer features , at some point your going to need to perhaps upgrade something along the way ,

and the fact you said you did not have internet access makes upgrading a bit more of a challenge ,

Thank you for your input. I was able to get 10.04 loaded somehow. It wouldn't work before which is why i used hardy......go figure. So, now i have the machine doing the latency test....looks good. Im wondering if there is a step by step instruction from this point. I won't be near the machine till tomorrow but wondering where to start/finish with configuring the pc. I'm using the mesa 5i25+7i77 with brushed servos. I'll start going through the documentation but any help to move this along is appreciated.

simple enough use pncconf to produce a working file , then if you need to modify it , edit by hand
make sure the field power is powered up before the pc , or you'll find gpio pins are missing

Wow. I had been running 8.04/2.5/P4 on a lathe and was delighted with it.

Then the hard drive conked out. No problem, I thought, I had a spare hard drive and was able to save most of the critical Linuxcnc config files before the old hard drive ceased functioning all together.

So I installed 8.04 on the new hard drive, attempted to update to 2.5 and no joy. Apparently those Hardy repositories are no longer available?

Following the advice here to forget about 8.04 and move on, I gave Wheezy a whirl on a live USB. Latency 222,571. WTF?

I know the official response is that I'm supposed to upgrade my hardware but money is tight and the P4 was a good machine with 8.04/2.5.

For now I'll try running 2.3 or whatever came standard with 8.04. Maybe eventually I'll have time to give Arceye's 2.4 & 2.5 patches a whirl. I'm kinda bummed.
