content: I'm looking for "raspberry pi compute module" alternatives.I need it to run linux, have eMMC Flash, LAN, display (just for basic interface) and few other IO pins and J-TAGPreferable, just plug-able SMALL board.I googled out some options but I'm not very satisfied. Any suggestions?

content: Well, i believe all that could be done with embedded ethernet controller that has IO pins and web server but i need more comfort. Having Linux is so much easier.Basically what i said:Passive device, that from time to time gets some input via LAN/(HTTP), make some http requests and displays some basic info. And maybe control one switch. And all that with Linux, because i would need some simple web configuration on the device.That is about it.This is great but very expensive and seems to be focused more on (OpenGL) support. I don't know...https://store.gumstix.com/index.php/category/43/

content: If you don't mind putting up with Nvidia's proprietary libraries for the graphics side of things then this:https://developer.nvidia.com/jetson-tk1No OpenCL yet, but they of course support CUDA for parallel computing, OpenCV for computer vision and OpenGL for graphics.https://developer.nvidia.com/get-started-jetsonI asked for one for xmas to my wife, let's hope she didn't get me something related to "The Jetsons" instead. But it's cheap enough that if she doesn't get it I might, or wait for the 64bit version of the Tegra K1 if they make one.

content: Quote from: nardev on December 15, 2014, 04:02:41 amThe gumstix COMs are expensive, but they're also very powerful and very flexible. Dozens of GPIOs, SPIs, I2Cs, McBSPs, integrated HDMI, Ethernet (without requiring a USB Ethernet module), wifi (without requiring a USB wifi module), and a GHz CPU. If you need that kind of power and flexibility they're very nice. If you don't, then you're wasting money. Power consumption is relatively high as well due to the compute power. Without wifi or ethernet and with the CPU clock dropped to the minimum, you're still looking at upwards of 1W idle power. However, given their I/O flexibility, DSP core, integrated HDMI, ethernet, wifi, and COM form factor, they can be a very good choice if the application demands it.That said, from the sound of it, you don't need nearly that much power. You need a network interface, http server, and a GPIO or two. This is really uC territory plus an http server, and I'm afraid I don't have a lot of experience in that realm. Good luck to you.

content: There a lots of modules around. The biggest problem is that the board support packages usually are riddled with bugs. IMHO the best thing to do is to use the kernel and a standard Linux distribution like Debian or Ubuntu. With >1GHz, lots of memory and an Sata hard drive or SSD the embedded Linux system is fast enough to compile in the system itself. Cross compiling is a real PITA.
