Building RTEMS (Real-Time Executive for Multiprocessor Systems) for Coldfire using Opensource Tools

It really took me a couple of days to set things straight for a successful build. Here are the steps that I followed. Before starting, make sure you have ca. 1GB free space as the temporary files can easily consume a lot of space. I built everything on andLinux running on a Windows XP host. […]

Increasing the disk size in andLinux

Stop the andLinux service and make sure no colinux daemon is running. Download dd for windows and put in the same folder as base.drv or wherever your “/” drive image is located. The following command extends a 4 GB partition to 16 GB: dd bs=16384 if=/dev/zero of=base.drv seek=262144 count=786432 The seek=262144 tells dd that it […]

andLinux Error: “cannot connect to X server”

If you encounter this error, you should check the following: that the given IP address, which indicates your display, is reachable, either using ping, telnet, or some other approach that Xming.exe is running. You can check it using Windows Task Manager. If everything seems working, then you may try killing the Xming.exe from Task Manager […]

Installing QEMU on andLinux

Follow these steps: apt-get install gcc-3.4 ln -s /usr/bin/gcc-3.4 /usr/bin/gcc34 cd /usr/src apt-get install libsdl1.2-dev apt-get install libsdl1.2debian-all wget tar -xvzf qemu-0.9.1.tar.gz cd qemu-0.9.1 ./configure (This selects all available targets) make make install

Solving: Samba not working in andLinux with domain users

If Samba share fails to mount during boot-up and you are a domain user, do the following: Edit /etc/smbpasswd Change the first line to username = <Domain>/<Username>. e.g., devel-net/andy The password in the second line should be the domain password Now restart the andLinux service. The share should mount okay.
