Hy people, Please, I have again an error with Oberon System 3 R 2.3 Compilled. (I pray thay the new version is most better than this). During run-time I receive this simple mesage: XO> Main.StartRobot ~ ...::: Starting robot controlers... [BEGIN | EXCEPTION] - Trap kind: Instruction-Fetch from No-Execute Segment - Task Entry: Shells.ExecutionHandler.Run - Task Id: 15 - Task Status: Halted - Trapped Procedure Frame: Robot.Robot.StartController - Current Instruction Pointer: 008D1D0CH - Relative PC: 44084 - Stack Dump (Imprecise) Follows: Robot.Robot.StartController PC: 44084 @for = 3 i = 4 robot = 100B6EC0H Main.StartRobot PC: 8100 err = 269018688 Shells.ExecutionHandler.Run PC: 3812 e = 1008E640H Tasks.Terminate PC: 48240 [END | EXCEPTION] XO> And, off course this command has stayed as: 15 "Cmd: Main.StartRobot" THREAD HALTED normal For a language/system considered Real-Time this is a problem... I can not stop this halted command and loose the controll of the system because some flags indicating wrong information... The big problem is: what does this menas: "Trap kind: Instruction-Fetch from No-Execute Segment" ??? Using the option "* \Nnf"of the compiller, I discover that it is pointing to the statement: robot.controlFBTask.Start; in the middle code of Robot.StartRobot. This mesage does not help because this error only occours after I change the controller type of the robot and this only occours with one specifically type of controller. Using the others controller this error does not happen. So... how can I discover the real point of the problem!? And why Oberon Systems halt real-time tasks when a exception with them occour? Does it have a way to discover during run-time the real-state of a task? thanks in advance, Fernando Passold .............................

Previously I was interested in using parallel port Zip for transfering between machines, but the advance of technology has made IDE HDs so cheap that it's easier to move them between machines. I'm still interested to see code for Zip (or any other devices) par-port drivers. -- Chris Glur.

The commands under the heading "-- Installation image for bootable CD --" in Aos.Tool shows how the CD image is generated. The Partitions.SetConfig command at the end contains BootVol definitions that specify volumes to be mounted at boot time. You could create a boot CD that additionally mounts a hard disk partition. Booting from a floppy might be simpler, since it is possible to write a boot floppy from within Aos. >What is the e-mail address of the oberon mailing list? > oberon(a)inf.ethz.ch See http://www.lists.inf.ethz.ch/mailman/listinfo/oberon for subscription information. cheers -- Pieter >Cheers >Christoph > >-----Ursprüngliche Nachricht----- >Von: Pieter Muller [mailto:pieter.muller@alumni.ethz.ch] >Gesendet: Samstag, 22.

Native & DHCP
by Treutwein Bernhard 25 Mar '03

25 Mar '03

Hello all, does somebody have some hints about configuring Native Oberon for DHCP ? Google finds the XO/2 pages (http://xo2.org/) and the note on http://www.oberon.ethz.ch/betainst.html that "Oberon will also support DHCP soon" -- Bernhard Treutwein Bernhard.Treutwein (at) verwaltung.uni-muenchen.de (work) BdT (at) wildwein.de (home)

So basically it gets you away from > having to have a single type hiearchy? I'm not sure whether I would say it like that. Talking about having a different type hierachy I probably would reserve for Interfaces (See Bluebottle Paco = PC.Compile) BTW, I just learned from Patrik that already NO November 2001 knows about delegates. So AosIO.Mod also for Native can simply use this feature and the problem is gone. Sender* = PROCEDURE {DELEGATE} (... Receiver* = PROCEDURE {DELEGATE} (... Hey, why didn't I just come up with this idea myself and try it without bothering you :-( Cheers, Edgar -- edgar(a)edgarschwarz.de "http://www.edgarschwarz.de" "http://www.edgar-schwarz.de/forum/oberon" Running Active Oberon Make it as simple as possible, but not simpler.

If you just want to save what you can from your dead (non booting) partition I would try to add a second disk and then copy the stuff over. Whether you do this with Bluebottle, Linux, W98 or other stuff you boot from CD or diskette doesn't matter.

I understand that BlueBottle uses/extends much of the native-oberon code ? My 2001 version of n-o shows no applicable *ip.Obj . Where would I see some n-o appropriate/modifyable source code for Iomega Zip drives, with out being *swamped* by BlueBottle ? -- Chris Glur. PS. the recent c.l.o. post about having to throw away your Wirthian code every 6 years makes me more worried about my investment in n-o. Continuity, of course is the main reason for the success of WinTel.

Chris, cg> We need a documented simple method the copy from notebook to pc via n-o. If one of the machines can provide an FTP server from BlueBottle or Linux, PPP would also work over the null modem cable. Did the photocopy of Ch. 15 arrive there yet? Regards, Peter E.

Even down to inspecting & manipulating on partitions, sectors - as I remember. Have you got a spare partition; or one which you can sacrifice ? Apparently not. Under n-o you could make it n-o type and copy the files across. Apparently you don't have a minimal linux boot disk ? Have you got a spare machine which can also run V24.Obj ? Perhaps you can spend a few minutes to document how to modify the existing V24.Panel functionality to : V24Gadgets.Send <file> ? Then perhaps you can make a Configuration.DoText script of:--- V24Gadgets.Send <file1> .... V24Gadgets.Send <fileN> -----end script And go for coffee, it it's a bit slow. We need a documented simple method the copy from notebook to pc via n-o. The nul modem wiring is available. Remember V24 needs to find the port closed/free. -- Chris Glur.
