OLR and data storage.

Hello, In OLR, has anyone found a way to store user data separately from OLR system data? As a specific example, OLR is installed in /home/peter/olr on the HDD. User data is in a SDHC card. The SDHC can be mounted at /home/peter/olr/SDHC. ls /home/peter/olr/SDHC/* shows the contents of the SDHC. System.Directory ./SDHC/* ~ shows nothing. Does anyone have a clever solution? Thanks, ...

Astrobe for FPGA RISC5 Oberon
by Chris Burrows 04 Oct '15

04 Oct '15

I am currently developing a version of the Astrobe IDE which hosts the Project Oberon FPGA RISC5 compiler on Windows. With the work done so far I can now develop RISC5 Oberon software on Windows using all the Astrobe IDE features. When the edit / compile cycle is complete the resulting code can be synchronised with the Project Oberon system running on FPGA hardware via the RS232 connection. A single Astrobe command (Build / Rebuild) can be used to automatically recompile ALL 23 core modules of the Project Oberon operating system - about 9000 lines in total. The whole process (including generating disassembly listings) takes 700 millseconds on my PC. The eventual aim is develop a minimal embedded version of the Project Oberon OS e.g. just the Kernel, loader, filesystem, SPI, RS232 and SD card support. As development is done on Windows the higher-level layers of the OS with the user-interaction features e.g. GUI, display, VGA, mouse, keyboard, compiler, editor etc will not be required. This should be easier to port to simpler FPGA development boards than those currently supported by the full Project Oberon OS. When it is publicly released later this year the software will be made available for no cost. Anyone who is interested can get the latest progress reports and release announcements by following the forum "Astrobe for FPGA RISC5" on the Astrobe discussion forum: http://www.astrobe.com/forum/ Regards, Chris Burrows CFB Software http://www.cfbsoftware.com

Would this work for ETHO?
by eas lab 04 Oct '15

04 Oct '15

Newsgroups: comp.lang.oberon I created an <automatic menu syntax-directed multi-language> writer, [the next stage after syntax coloring] some months ago, and after being diverted to urgent problems, couldn't see how to use it, now that I'm free to continue refining it. Writing *THIS* will help me SELF-explain how it works? It uses wily: the public domain version from plan9, copied from ETHO. Using ETHO terminology: midMouse = MM = Execute the Command [with name = token-klicked-on]. wily doesn't have ETHO's restriction: that a valid command is <M.P>; but let's see for ETHO. So, at the start, the user loads a TextFrame containing only: START.p START.p is a command [M.P in ETHO terminology] which: replaces the textString "START.p" with eg. the 7-lines: "MODULE ModID; CONST ConstDecls.p; VAR VarDecls.p; PROCEDURE ...... BEGIN Statements.p END ModID." And eg. Statements.p is a command that replaces the textString "Statements.p" with eg. " KnownID.p := Expression.p IF ............ WHILE ............ REPEAT ........... FOR ........... END .... ------------------------------ So, essentially klicking any <hot Tokens> replaces it with it's expansion. It's a type of syntax directed menu. Let me get back to wily, and you write an ETHO prototype. Oh, for ETHO you'd use eg: x.START , x.ConstDecls , x.Statements ,x.Expression

build of A2

Hi. I'm trying to make a build of A2. The actions I take from the "Release.Tool". Perform "Release.Build --path="A2BUILD\" A2 ~" Then perform "Linker.Link \PA2BUILD\ \.Obx USB.Bin 0100000H 1000H Kernel Traps UsbHubDriver UsbEhci UsbUhci UsbOhci UsbStorageBoot DiskVolumes DiskFS BootConsole ~" Get a trap: ... StackTraceBack: Linker0.ThisType:17 pc=4585 [000011E9H] = 4568 + 17 crc=1D9B8D61 m=00000000H (NIL) name="@HdPtrDesc" i=0 type=00000000H (NIL) ... Found that Linker0.ThisType takes a parameter m in Linker0.RelocateModules:100 pc=7587 [00001DA3H] = 7487 + 100 crc=1D9B8D61 by call Linker0.ModuleByName(HdPtrDescModule) (*position 28196*) Definition of HdPtrDescModule = "Loader"; I add to linker list of modules module name Loader. Linker make USB.Bin with message: Linking USB.Bin Base=100000, load=1000 Modules:Loader Kernel Traps UsbHubDriver UsbEhci UsbUhci UsbOhci UsbStorageBoot DiskVolumes DiskFS BootConsole Linker0 Ok. #Bytes= 000BC420 Linker.Log Question 1: Error in Linker0 or in Linker.Link call parametr string? Question 2: In StackTraceBack formal parametr name="@HdPtrDesc". The actual parameter is HdPtrDescType = "@HdPtrDesc" (*position 847*) It's the only constant with the symbol "@" at the beginning. Is that right? Dmitry Maslov

So, name length failures are minimized by mounting the subordinate store at a directory with a single character name? Prefix being four characters, "./S/". ET.Open ./S/tmp456789012345678901234567890 ~ works. Therefore the Oberon limit of 32 or 31 characters isn't present. You refer to the Linux liimit of 255 characters? In that case the name of the mount point isn't critical. > Also pattern matching algorithm has a bug. E.G. System.Directory *.Mod~ > does not show Modules.Mod. If someone has a clever implementation, ... I guess one approach is to mimic the Oberon matching algorithm in C but others will have sharper ideas. Thanks, ...

Hi. I downloaded the release A2 6480 and tried to run "Release.Build --build WinAos ~". Received error message: Error(s) in file Win32.WinTrace.Mod Win32.WinTrace.Mod error: A2.WinTrace could not be compiled (checker errors). Win32.WinTrace.Mod@1097 error: undeclared identifier (selector) I tried to compile the "Win32.WinTrace.Mod". Got error message (pos: 1097) "undeclared identifier (selector)" at line: "IF Kernel32.AttachConsole(-1) = Kernel32.True THEN" Win32.Kernel32.Mod did not contain a definition AttachConsole. It's some kind of bug or I something not understand? Where can I read about releases A2, A2Cooperative, A2RPiCooperative, WINAOS, WINAOS generic? Sincerely Dmitry Maslov

Project in memori of Tibor Csuta
by Gábor Zoltán Sinkó 21 Sep '15

Hi! First of all, I'm sorry it might have been looking for you, but my source is not much different. The story is described in four simple. Years ago, I met a man who always kept a minimum of eccentrics, but because of his mind, I always respected him alive. Over the years, not only my friend, my teacher but I kept my mentor and friend is one of the best. Unfortunately, he died ... Maybe you knew they were obsessed preached among the disciples of the Oberon-worth and everything that goes with it. Who does not know Csuta Tibor died in 2015 szeptemer 18th. There was a project that I would like to finish here and to ask for help. The aim of the project was put on FPGA You can have the Oberon. That is, the project Oberon a little updating. I'd like to put down on the grave of a working prototype and put down your will. So I'm sorry if your English is not good (google), I'm sorry if I ask stupid things green, two road in front of you: Or barred from there and makes it very difficult project or take a minimum initial elites that will bother you. First I would like to turn the memory modules currently used to insert the ProjektObron git project, both staying separately. What you might know how to help you make the memories used nowadays where you can find Verilog source code that can be used os. honored Gábor Sinkó Hungary
