Hi all, I have two questions I hope you can help me with. The first is, im trying to port an existing microwindows application onto uClinux... ive successfuly compiled it using the nios II toolchain but when I run it it just spurts out rubbish on the screen. Its hard to explian properly but it doesn&#39;t do as its supposed to do!!! The second thing is in the uClinux application settings I tried to select nxlib under microwindows but it won&#39;t build properly. There are no errors given it just won&#39;t build. Does anyone have any experience on this? Thanx

Your error descriptions are really unusable :). I did install nano-x and nanomw and did a simple application using it and it does work as expected. Did you install the system completely according to the NIOSWIki and upgraded to the newest version using git ? Are you able to run a nanomw test application like nxview that comes with the system ? -Michael

I can get the demos working fine (tried tetris and clock)... just not my own application which was originally written for another version of linux (ive updated makefiles etc and rebuilt using nios toolchain) I&#39;m using the SLS distrubution that is linked on the Altera website. I tried the distribution on the nioswiki but I couldn&#39;t get the framebuffer to work. Unfortunatly its very hard to describe whats happening. It just prints garbage on the screen when I try to execute my application. I can just make out bad command amongs the gibberish.

SLS distribution ? Are you using the NEEK hardware ? If so, you might want to try my "binary Neek" distribution in the NIOSWiki. Same is based on a newer uCLinux version, and it comes with a simple working graphical application that I wrote. Of course the source code is available. -Michael

Hi, Where is this binary neek? (Yes I am using NEEK). The SLS dist can be found here: http://www.slscorp.com/pages/bspdownload.php (http://www.slscorp.com/pages/bspdownload.php) Their dist does seem quite unstable...SD drivers won&#39;t work and nxlib creates a build error... I wouldn&#39;t have used it but i can&#39;t get lcd display going on the dist on nioswiki

If you want to get support here, you need to switch to the current uClinux distribution as described in the NIOSWikl ( http://www.nioswiki.com/operatingsystems/uclinux (http://www.nioswiki.com/operatingsystems/uclinux) , using theses instructions: http://www.nioswiki.com/installnios2linux (http://www.nioswiki.com/installnios2linux) - including the notorious git stuff), You&#39;ll find my "binary NEEK distribution" here: http://www.nioswiki.com/operatingsystems/u...x/tryoutuclinux (http://www.nioswiki.com/operatingsystems/uclinux/tryoutuclinux) . -Michael P.S.: It&#39;s a shame that due to the server crash and the forum rewind to 2007, all information on all this in thousands of forum messages is lost. :( .

Microwindows on uClinux

Hi all,

I have two questions I hope you can help me with.

The first is, im trying to port an existing microwindows application onto uClinux... ive successfuly compiled it using the nios II toolchain but when I run it it just spurts out rubbish on the screen. Its hard to explian properly but it doesn't do as its supposed to do!!!

The second thing is in the uClinux application settings I tried to select nxlib under microwindows but it won't build properly. There are no errors given it just won't build. Does anyone have any experience on this?

Thanx

Both distribution are just for demoing what can be done. You can't really "use" them, as they are built using very outdated stuff. and are not supported by anybody. No help, upgrades or modifications will be available.

For decent tests you need to build your own distribution using the current version of the "distribution builder" from the git (as described in the Wiki).
