I have some experience developing on Linux systems and am looking to get my hands really dirty with Embedded Linux soon. What would be a good list of books someone could read to get a good grasp on Embedded Linux systems? Building Embedded Linux Systems seems to be a good starting point. Are there certain books or chapters of books tha...
I'm developing an application that runs on a small Linux-based SBC (~32MB RAM). Sadly, my app recently became too large to run under GDB anymore. Does anyone know of any good, lightweight debugging methods that I can use in embedded Linux? Even being able to view a thread's stack trace would be extremely helpful. I should mention tha...
I want to play around with some embedded linux. I want it to be able to run on an x86 processor (for start, it will be running on my regular PC). I have looked online, but the ones I have found seem hard to setup or lack proper documentation. So what are some good embedded x86 compatible linux distros that are easy to setup or have good ...
hi all, I need to display images on an embedded system. The board configuration is as follows: It is AT91sam9263-EK, with Linux 2.6.20 kernel running on it. Are there any image processing libraries for this board.The processor is ARM926EJ-S. thank you all ...
I have PHP installed on ARM91. It works fine until I use session_start. Then I get the following Warning: session_start(): read returned less bytes than requested This does not seem to be a permission problem - the sess_* files are created. When you try to put anything into such session, it creates sparse file (17GB size) for the session...

I am attempting to use objcopy to convert an xml file to an object file that is then linked into and used by another shared library on RHEL5. I convert the file with this command: objcopy --input-format binary --output-target i386-pc-linux-gnu --binary-architecture i386 baselines.xml baselines.0 The object file is created and using rea...
I am evaluating Embedded Linux GUI toolkits for an upcoming project and have put together a must have “feature list” to help me with the decision: Color gradients in graphics (for menu headers buttons, icons, etc…) The ability to draw complex wave graphics with say a background grid, notations. The ability to swap between to landscape ...
I am working on an embedded linux kernel project for a 83xx powerpc using a 2.6.24 kernel and having some issues extracting information out of the open firmware DTS file for a i2c device driver. For a memory mapped device I would add normally add entry in the DTS file that specified the address / IRQ parameters etc. Then in the associat...
Hi All, I might be approaching this all wrong but... I have a linux kernel device driver that handles an external interrupt and currently performs a printk() when it occurs. What I would like to do is tell a user space app that this event has occurred so it can wake up and do some stuff. Is it possible (/simple /good practice) to s...

I set-up the Kamikaze toolchain (from openwrt), and compiled Linux 2.6.30.x kernel for an AMCC PPC405ex kilauea reference board. However, for some reason I am doing something wrong in uBoot, as I am not able to run the kernel from an squashfs image. The image loads fine over tftp and uncompresses, but the console output does not start. ...

I know basics of electronics like transistors, flip-flops, multiplexers.. etc. I love software and would like to create something like E book reader. Is it possible for a software engin...
Hello all, I am working with an electronics appliance manufacturer to embed LAN based control systems into the products. The idea is to serve up a system configuration/control interface through a web browser so clients never need to install software. We can communicate with the appliance by sending and receiving serial data through the ...
