Hello all:

I had purchased recently a dev board from IC-Board AP-7000 base (also known as grashopper) with pre-loaded linux on board.

Since I live in the 'AVR8 smoking' side of life and my bit-pushing knowledge is limited to Windows, C for AVR8, some OS9 and a heavily dust covered limited knoldegde of MS-DOS, I'm totally lost with Linux.

Hence my question to the wisdom of this forum: is there a good link to some document like 'Linux for dummies', 'Learn linux in 1nanocentury', 'Linux Quick-Start' or similar where I could begin to learn the basics to do somethin with this nice beast?

Thank you very much in advance,

Guillem.

It is worth noting that because Linux is so open, you can eventually find most things online somewhere.

Often it is easy to learn from a dedicated source.

There are quite a few books on the topic, the difficulty is finding one that meets your current level of understanding.

Before you go spending momney on books check out the following resources listed on the wiki at:

https://www.avrfreaks.net/wiki/in...

I would highly recommend that you set up a Linux desktop PC to play with so you can learn about init levels, scripts, /dev filesystems etc with a screen and keyboard and not via a terminal.

Have a look over the issues dealt with in the Wiki for the sort of things you will need to focus on to learn.

It might be worth trying to play with LEDs as a first step without playing with Kernels etc

Right now, my goals are:

1- Mount an SD Card unit. HW is damn simple (six or seven wires). I understand this is a relatively simple project, although not as simple as LED blinking.
2- Connect a 5" LCD TFT I've adquired to IC-Board and try to show something. I think this is not easy for me (HW is again simple).
3- Connect a 7" LCD TFT we use (as component in our production line!) as display (HW can be complex, since there are two options: simple paralel 18bpp, or LVDS trhough a serializer).
4- Integrate the module into our production line to test the TFT's...
5- Develop my own PDA ;)

Anyway, I agree that I first have to try to walk before run, thus I will add some simple steps between projects 1 and 2. I will also ask our IT dept. to have a Linux powered PC, although this can be somewhat complex (big companies want to control each PC). And at home I don't have (still) a free PC to do that. Would Cygwin be usable?

Linux under Windows on VMPlayer makes a good sandbox to play in. Various virtual machine downloads are available, one is http://www.sics.se/contiki/instant-contiki.html.

I've just managed to do some things with this board now, so thank you all for your help about this issue.
