I started looking into the graphic card programming especially Nvdia CUDA stuff. After getting the SDK compiling under Fedora 12 (so far only possible with compat-gcc) first examples could be tested. It is quite impressive how fast and nice some tests look like. To get somehow familiar with the framework, I wrote a simple memcpy Continue reading →

During the vacation time a lot of code changes were made. Now it is time to write a little bit about the changes. The first thing was to write a Cypress USB to wishbone interface which gave the possibility to connect wishbone compliant modules to USB. As testcase the wishbone lcd driver should help to Continue reading →

Since Fedora 9, the init process is managed by upstart. To get a serial console with a login prompt the old method doesn’t work anymore. The old method is to add the following line into /etc/inittab: s0:3:respawn:/sbin/agetty -L 115200 ttyS0 vt100 This spawns a agetty for the ttyS0 in runlevel 3. The new method is Continue reading →

The variable “@local_domains_maps” in the configuration only has my domain. This brings the failure that Continue reading →

Ok, now the second part of this cypress story. The source which is provided by cypress contains some demo projects, for my test design which should put the board into a peripheral mode, the demo “de2″ is a good starting point. After some browsing through the code I saw that this demo puts SIE1 (Serial Continue reading →

There are a lot of possibilties to manage the qemu kvm monitor and serial ports. Here is one solution to provide these two ports for a user which only has a chroot home with a small busybox (with microcom). First of all qemu-kvm has to know how the interfaces should be exported. This solution uses Continue reading →

Starting situation is an installation of Windows XP and Fedora 9 on the hard drive. The goal is to start Windows from Linux with the KVM virtualization solution. First step is to create a second hardware profile inside windows, this is necessary because windows should be bootable from the virtual machine and native hardware. Then Continue reading →
