Re: [rtl] [off-topic] Via C3
I am having the same problem with 2.4.18 on an amd k6 - 266. I tried setting the processor to the k6 setting but with the same results. Could this have anything to do with using some older tools. I am currently using an rtlinux 3.0 CD installation with 2.2.18, and just downloaded the new kernel and compiled.

[rtl] Off Topic - Network Broadcast
I'm sure this is an easy question for anyone who is a network expert... We have a local network with embedded computers. What is desired is to send a packet that all the embedded computers will receive. Is there such a broadcast command ? Is there a good book with an example ?

Re: [rtl] Off Topic - Network Broadcast
Yes use the broadcast address. Depending on what protocol you use this will be something like 255.255.255.255 for IP or ff:ff:ff:ff:ff:ff for ethernet or something like 0.0.0.0.ff.ff.ff.ff.ff.ff for IPX. a good reference is UNIX network programmming by W.

Yes, there are broadcast tcp/ip messages. The "standard" books are by Stevens. Either Unix Network Programming or Advanced Programming in the Unix Environment (2 vol).

Don't use proto 90-00 and send random broadcasts to it, that definitely will confuse a number of other systems. 90-00 is the loopback protocol, which is implemented in a lot of places. If you're going to pick a protocol number for random protocols, pick one intended for that purpose. A nice one is 60-00, which is a DEC number and was assigned by DEC to "Customer use". So you can reasonably safely use it for uncontrolled use. Certainly you should be able to count on it not being used by any "real" products. paul -- [rtl] --- To unsubscribe: echo "unsubscribe rtl" | mail [EMAIL PROTECTED] OR echo "unsubscribe rtl Your_email" | mail [EMAIL PROTECTED] --- For more information on Real-Time Linux see: http://www.rtlinux.org/rtlinux/
[rtl] off-topic: need automatic reboot information
Hello, I have an off-topic question that I think the people on the list might be able to give me some hints or point me to the right direction. I have an interrupt service routine that interrupts the operating system (currently Win 95) very often (on the order of 2000 times per second). In addition, there are other programs running that has file access, fixed point and floating-point calculations, and memory allocation and freeing that are happening when the processor is not being interrupted. The computer is not happy since it would reboot itself from time to time. Could someone let me know when and how a typical operating system (RT-Linux, Linux, and Windows ) or BIOS decide to reboot the computer ?

[rtl] off topic
Hi i have a question not really regarding rtlinux in special. we have to communicate with our a/d adaptor which is realtime capable on its own. the problem is that the task which is installed directly on the adaptors cpu was compiled under DOS/WINDOWS. The task running on the pc (now under linux) was compiled with egcs - which has a 4-byte alignment in contrast to the 1-byte alignment from DOS compilers. so all our structures are different in size and we only transfer bullshit to and from the a/d adaptor. does anybody know the command line switch or pragma to change the default alignment of gnu cc or egcs??

Try using the following declarative construct for every involved
struct:
__attribute__ ((packed))
Test program (prints '8' without the attribute, '5' with it):
struct s {
unsigned int i;
char c;
unsigned int j;
} __attribute__ ((packed)) a;
main()
{
printf("offset = %d\n", ((unsigned int) a.j) - ((unsigned int) a));
}

At the company I work for, there has been a discusion about relability of CAN interface. I am awared of some implementations for flight simulators, but I have no data concerning real thing. That is the origin of my question. I may say that I am interested in CANbus driver and interface card to. Which OS? CANbus driver source also? Are you looking for a CANbus driver that has been approved by the FAA for use on commercial aircraft? What are the special requirements for your application? Are you interfacing with pre-installed equipment? At the moment we need some general info, since we are exploring posibilities to connect old aircraft cockpit (for instruments driving purposes, as well as data aquisition) via CAN bus. We would like to use Linux as OS. Another (possible) requirement is that I would like interface with hardware to be done as a RT-linux task. - Kal. Gordan Sikic wrote: Hello!
