I am experiencing a very bizarre problem with vxWorks and I am hoping that someone might be able to offer some suggestions on where to start looking to determine the root of the problem. VxWorks is being used on a Synergy Microsystems VME SBC which is PPC based. The problem seems to arise at random times after rebuilding the OS image. For instance, by commenting out a single 'printf' stat...

I've been asked to write some articles about developing an example Linux-based embedded app on x86 and porting it across to a PowerPC platform. When I was contacted by the people that want these articles, I said that I hadn't worked much with PowerPC because PPC-based SBCs are so expensive that they've generally been thrown right out of the race at the start. Unfortunately, that still seems t...

Hello, friends! I'm searching for some cheapest SBC to run a web and sql servers in my home local network. It should perform a query to 100,000-records phone directory. I do not think that the whole PC is a suitable solution - I want it to be silent and power-efficient. At the same time, I don't want it to execute the query for 5 minutes - it should be fast enough.

I'm evaluating the Beagle Board for a small application. Any comments on software tools and build environments are welcome. My project involves interfacing to a small display and a keypad (between 6 and 10 keys) and communicating via ethernet to a master controller. This board may be overkill for my needs but it is cheap ($150). Comments welcome.

We are getting ready to start a new product and we are leaning to ThreadX for the RTOS (our second choice in montavista) . We want to base our architecture off of PC/104. I wanted advice on a SBC that is PC/104 (or has a PC/104 bus on it) that is very easy to get ThreadX, NetX and FileX up and running on. The board needs to have Ethernet (that NetX will work with) and USB. Order of prefe...

I have access to some 486 (and 386) single board computers that I'd like to utilize for some one-off projects.

I have, BTW, programmed plenty of embedded stuff using other processors. Can any of you folks who have done so tell me something about my options in...

I've also tried deleting the MasterIdDataChec...
