ST Linux with Busybox

Hello.

Im trying to use a wifi usb dongle stick in a satellite box decoder I bought this christmas. This box is a mvision HD 7000 Linux. I have managed to find out about kernel version inside.

I can uncompress the driver but the problem I have is that I cannot compile it running "make" included, no updates engine are installed in the box, tried apt-get,yum,etc.. It seems like they have uninstalled the updates, and compiler plus many other things, How can I get them back, how do I simply install this driver, can I do it compliling it from other linux?

-bash-3.00# uname -mrs
Linux 2.6.23.17-stm23-STAPI-A21-grayrose sh4

-bash-3.00# cat /proc/version
Linux version 2.6.23.17-stm23-STAPI-A21-grayrose (marin@jujube) (gcc version 4.2.4 (snapshot) (STMicroelectronics/Linux Base 4.2.4-62)) #1 PREEMPT Fri Jan 4 11:33:12 KST 2013

-bash-3.00# man
BusyBox v1.15.3 (2011-03-29 11:30:33 KST) multi-call binary

I have root access and the folders installed are:

bin
dev
dev.static
etc
lib
media
mnt
proc
root
sbin
sys
tmp
usr
var

Could you give me some help with this?.
Thanks.

Welcome to LinuxQuestions.

There is nothing to get back and nothing was uninstalled since the decoder is not a standard computer with a typical desktop linux distribution.

busybox is a minimal shell designed for embedded systems. I would guess the decoder box uses a single board computer that runs from flash so there isn't enough memory for any sort of extra stuff like source code or headers to compile a program.

If you knew what type of processor the decoder uses it might be possible to set up a cross compiler on a regular PC linux distribution. Without knowing anything about its internal workings I would say they there is no simple method.

I am moving this thread to the embedded forum to get the exposure it deserves.

Thanks for your reply Michael.

I find quite interesting your reply, and Im really looking forward to be able to cross compile from a PC to then send a driver for my wifi stick. I found the developers webbage were I can download this distro, but how do I know which arch etc..?

Architectures:
ARM
ST200
ST40

I believe the hardware is as shown in about page:

Model name HD-700L
Software Version 0.5
Plugin API Version 0.0.11
Loader Version 1.3.1-8
Micom Version 0.03
Mainboard Version R02
Nim 1 FE900

I found some instructions with cross compiling sh4 architecture , my question is : May I be able to comile a driver I found zd1211-vendor.tar.gz and copy it to the decoder box once is compiled?, or should I compile a full kernel with the driver embedded?.

Thanks
Best Regards.
