Scope I got myself an Armadeus APF51 board for some work combining a fullblown ARM processor running embedded Linux with a recent Xilinx FPGA. I wrote down some setup notes for possibly future need while setting it up for work, and they are below. There is not really something undocumented here, but it’s more convenient [...]
The problem The Xilinx Microblaze soft processor, which is implemented on the FPGA’s logic fabric, is indeed a stable and fully capable processor, but its rather low clock frequency — 70-100 MHz on a Spartan-6 — makes it a problematic candidate for data capture and frame grabbing. When running Linux on Microblaze, the current kernel [...]
If you want to get to it, just go to the Xillybus mini-distro for Microblaze’s page. This distribution is a software kit, which allows you to run a functional Linux system on the SP605 or ML605 hardware evaluation kit (for Spartan-6 and Virtex-6, respectively). All components necessary to build it will be available for download [...]
As usual with those fancy Gnome themes (as came with Fedora 12 in my case), the basic assumption is that you’re a not-so-clever user, so not too many choices should be left for you. So pick one of those premade alert sounds. Picking your own sound file? Noooo. That’s way too much freedom for a [...]
Merely for myself, so I’ll remember how to do it. I’m not good with git. If I’m doing stupid things, please comment below. Rule #1 If you’re about to do anything with git being unsure about the consequences, always protect yourself with $ git branch bettersafe $ git commit -a $ git checkout whatever Assuming [...]
This is part IV of my HOWTO on running Linux on Microblaze. The outline is as follows: Part I: Introduction and setting up the Microblaze processor Part II: Compiling the kernel Part III: Preparing for boot and booting Part IV: Compiling user space applications (this page) Compiling user space applications We shall now look at [...]
The setting I got an AudioCodes MP202B as a phone line adapter from my Israeli ISP, Netvision. The normal way to connect it is putting it between the computer and the ADSL modem, so it does the “dialing” (sending username and password). This was a no-no for me, because I have a little home network [...]
Making a custom ISO image. It turns out it’s no so difficult to make a custom LiveCD / LiveDVD / LiveUSB, even if that includes making small hacks in the target system’s outline. Just follow this guide. Creating the liveUSB Create a liveUSB from a liveDVD image with liveusb-creator. Download the ISO image, don’t let [...]
Writing udev rules is well-documented all over the web, but I still wrote down my own quick summary, so I have it handy for the next time. Following this excellent guide, I plugged in the USB stick and went $ udevadm info -a -n /dev/sdd Udevadm info starts with the device specified by the devpath [...]
This is just a raw dump of PCIe communication. I wrote a small sniffer on an FPGA and ran some data in a loop to and from the peripheral. The sniffer’s own data was stored while sniffing, so it doesn’t appear in the stream. The whole thing ran on a Linux machine. I thought that [...]
