Hello World on arm926ejs (continued)

Thanks for your advices.
I have now downloaded from the OKL4 wiki the binary version of the arm-unkown-linux-gnueabi crosstool chain and recompiled from scratch the singlecell example within the binary SDK. The images are well generated but they don't work better on my host than the images I have built in parallel with my own crosstool chain... In both cases a warning exception is raised because no DNS server is found, which is a little surprising when the test is performed locally. "Warning: No DNS servers found" This problem doesn't seem to be blocking and occurs also in other qemu use cases contexts as I can when googling a little on the subject... But perhaps this explain what happens after ? I don't know ! So when I run qemu with the following command: qemu-system-arm -s -M versatileab -start-addr 0x07900000 -nographic -kernel build.micro-debug/images/image.elf the warning is printed on stdout and the process enter in an infinite loop without printing any "Hello World" message... I've tried to debug with gdb by starting qemu with the '-s' option and running gdb, loading the symbol table of the "hello" program and opening a remote target connection to the default local port 1234. After the connection to the qemu process I typed 'c' to continue the execution and then stopped to see the stack... No symbols are readable... Only some ?? and 0x0.... I don't have change the endian-ness ( little by default on PC and ARM ). What is surprising is to see the entry point address settled to 0x7900000 only in the image.boot and image.sim files and not in the image.elf nor in the image.elf.nobits files. Another suprising thing is to see the following message on stderr when viewing the full symbol list of the elf image thanks to "readelf -a" ... 2247: 8000fba0 4 OBJECT GLOBAL DEFAULT 6 hello-_kr_malloc_freep 2248: 8000fec0 4 OBJECT GLOBAL DEFAULT 6readelf: Warning: corrupt note found at offset 0 into core notes readelf: Warning: type: 1, namesize: 00000011, descsize: 00000300 hello-sys_siglist 2249: 8000fba4 4 OBJECT GLOBAL DEFAULT 6 hello-__malloc_bss ... You can also find here attached the elf header so as the system traces when I run qemu with the image.elf file....( I have splitted the end because it is a periodic repetition of getimeofday and select calls... ). Concerning the compilation of qemu, I have tried both with gcc-3.4.6 et gcc-4.2.4. No differences when loading the image.... The compilation process of qemu-system-arm seems to be ok because I have tried it with another SDK ( namely for the kzm platform supporting arm1136js processors ) and the hello elf image runs well for this target. In that case, the readelf -a command doesn't raise a warning as for the arm629ejs target ! To sum up the hello world is ok on my host for arm1136js but not for arm926ejs, and I think something goes wrong with the SDK for arm926ejs... Did you have tested the singlecell example after recompilation from scratch of the crosstool chain and of the SDK-arm926ejs ? Could you please try the image I have sent to you in the preceding message to check if you encouter the same troubles with it ? On the other hand I could try a 'reference' image.elf file the singlecell example on arm926ejs that you can send to me in order to test if the problem is due to my system environments or not ( ubuntu hardy and gentoo based-systems ).

Hugues,
Checking round here, the SDK for the versatile is not set up, in the _debug_ kernel, for use with qemu. It (the debug kernel) is configured for use on the hardware (with JTAG). This needs to be made clear on the wiki. To get the example going, you should use the make line make BUILD=production and then change the qemu line to refer to build.micro-production/images/image.elf (or image.sim) That should allow you to see the examples running. Going back to your original email(s) I understand your intended target _is_ versatile. If you want to contact me off-list we can go through in more detail how to build either from the source or re-build the SDK to have it set up as you want. One other thing. We haven't seen the readelf errors that you are seeing (running on the image you provided). I suggest you try the arm-unknown-linux-gnueabi-readelf in the toolchain.

Now after having tried the Hello World example successfully, I wonder if its possible to configure precisely the temporal scheduling of a multi-cells system.

I that possible to add such kind of temporal constraints ? exemple: to force the chatterbox to be scheduled during the first demi-period and the echo during the second... Perhaps you have some other examples more focused on temporal partitioning ? Another quetion I asked me is to know how it is possible to respect a strict temporal partitioning while having a synchronous communication mechanism between two different partitions. In other words, synchronisation without buffering implies some kind of "context switching" from one address space to the other each time an OKL4 IPC call occurs... How is it possible to respect a fixed temporal partitioning with that kind of communication mechanism ( for example to force execution of adress space 1 the first milliseconds and of the address space 2 after etc... ) ? Here is an extract of a presentation of OKL4 from Gernot Heiser Message-passing in OKL4 is always synchronous (rendez-vous) • Message gets transferred when sender and receiver are both ready • The party attempting the operation first blocks until the other is ready ïƒ Implications: • Implicit synchronisation • No buffering of data in the kernel • Data copied at most once I have another general question on the relationships between the OKL4 API and POSIX... Is it possible to have some kind of "adaptation layer" between POSIX and OKL4 in order to enable a POSIX source code to run on top of an OKL4 address space ? Another question deals with the support of linux-based drivers... Do we need to install an OKLinux OS inside an address space to be able to use a linux-based driver... In that case how can we share the driver between different adress spaces ?

Thank you Peter for your answer, I have tried to compile the OKL4_3.0 archive with the command line you gave to me and got the following error: Executing: licence_tool --type=sdk --mode=expand /home/hugues/tools/okl4/okl4_3.0/build/SDK/object/sdk/sdk/okl4 sh: licence_tool: not found scons: *** licence_tool returned error, perhaps it's not installed? So I suppose I have to install some kind of license tool and don't know how and what are the underlying conditions... Thanks in advance, Hugues.

Hi all, is it possible with OKL4 to respect a fixed temporal partitioning like in ARINC 653 ? For example with the GreenHills Integrity operating system we can plannify a strict scheduling for our application by a file descriptor to allocate each time slice to a specific partition, as the one joined to this mail... Would it be possible to imagine the same kind of example running on top of OKL4 ? Regards, Hugues.

Hi Hugues,
Please comment out the following lines (1797 and 1798) in tools/kenge.py: if ret != 0: raise UserError, "licence_tool returned error, perhaps it's not installed?" to work around this issue.

Dear Hugues,
we have done work in that area here at NICTA/ERTOS. The code is by now outdated (that was student work on an old kernel version which so far hasn't received the cleanup to be published). Google for RBED and Scott Brandt. That's roughly what we implemented (there's currently a paper in review, the fate of which should be known in a week, in which case we should have something public in a couple of weeks. Comparing with Scott's work we put the resource allocator into the root task and the actual task management into the kernel. I intend to pick that up again soon and it should be a piece of cake with the scheduler interface compared to the 1.5.2 we used. Regards, Stefan.

Hi Pierre-Paul,
When building from source, our SCons build system defines DECRYPT_MASK: examples/decrypt/SConscript:env.Append(CPPDEFINES=[("DECRYPT_MASK", 0x34)]) However, when building from the SDK (which is the recommend approach), you'll need to define this yourself somewhere. You can do this in the decrypt cell Makefile (by editing DEFINES) or directly in the decrypt main.c src file. Hope this helps, Best regards, Josh On Fri, February 20, 2009 5:55 am, sloly09 wrote: > > hi > I have a problem to compile the sample hello word exemple coming with > SDK > on arm926 ejs.
