SCALE writes "In marking 10 years of the Southern California Linux Expo (SCALE) and 20 years of Linux, the SCALE team wants to incorporate an open-source approach to this year’s expo logo designs for publications and for swag.
With this in mind, the SCALE team announces a contest to select the artwork for use on this year's conference materials.
The designer of the winning submission will win a free pass to SCALE 10x, including airfare within the continental United States, as well as a three-night stay at the Hilton Los Angeles Airport. SCALE is a community organized Linux and open-source conference held annually in Los Angeles, CA.
SCALE's call for papers is open through November 17th as well, we invite the Embeded Linux community to submit session proposals to our newly announced kernel and developers tracks."

| Articles: Universal (free) remote control library for embedded systems |

Martin Strubel writes "I'd like to announce a first preliminary and free OpenSource release of our device control library (DClib) and its mainly used protocol (netpp - network property protocol).
The DClib (device control library) and its netpp (network property protocol) extension is a framework that simplifies any remote or embedded control protocol greatly by using an XML device description language to describe register maps and generic device properties and turning this into compact source code that can be compiled as a remote control server backend for the specific device target."
Read on for a better description or check this video to see a simple command line application to remote-control netpp devices.

adpnic writes "There is an anomaly in the uClinux TCP stack involving two ports. To explain this assume that port A is using 142.42.6.114 with a MAC of 08:00:00:00:00:02 and port B is using 192.168.0.1 with a MAC of 08:00:00:00:00:01. If you are connected to port A and arp 142.42.6.114 it responds with 08:00:00:00:00:02 as the MAC. If you ARP for 192.168.0.1 it also responds with as the MAC 08:00:00:00:00:02 . The converse is true on port B. If both ports are connected to the same switch you will see a response from both ports. e.g. ARPing for 142.42.6.114 will get a response from the port B with 08:00:00:00:00:01 and the port A with 08:00:00:00:00:02.
We have tried this with both MMU and MMUless versions of uclinux. Also with a NIOS II configured with the altera TSE MAC and the OPENCORES 10/100 MAC. Has anyone else seen this problem? If so, is there a fix?"

Xadas writes "Hi,
i'm writing my bachelor thesis and need to program an application that is able to store processdata into a MySQL / Oracel database. Does anyone have experiance in using a database with uClinux ? Maybe a how-to or some sample application ?
I'm using the Lantronix XPort Pro ( Coldfire ).
A possible solution is crosscompiling a library like libzdb, but i don't know how to integrate a new library into uClinux.

| Articles: Multiple access to a single driver |
|

jponnoua writes "Hello,
The development board I'm using is a Coldfire (MCF5235) and the kernel is 2.6.
I've developed a CAN driver (char driver type) but until now one service only was using this driver. A second service using the CAN driver has been developed, so I need to modify my driver for multiple access. I was thinking about using minor number to identify which module is adressing the CAN driver. However, I don't know what kind of call would increment the minor number. In my case, I'm making one insmod for the driver, and one CAN_open for each service. The result is that the minor number is always 0 (or start value). It is not incremented. How can I increment this number?
So I've declared a static int Device_Open as global variable, and into the open function I increment it by one (into the release function, I decrement it by one). In that way, I'm able to do what I want but I'm not sure it's really nice do to in that way. What do you think?
Best regards,
Julien"
