Hi All, I need one information How much effort is required to port the the rSync utility to any of the RTOS available? (how much is the linux dependent code in the implementattion?) regards Thanks in Advance Biju -- Biju Perumal HCL Technologies Ltd. Voice +91-44-3728366 (Xtn-1134) http://san.hcltech.com

Hi, We have a proprietary RTOS which is *not* POSIX complaint. We want to port SSH server and SCP client onto our platform. How difficult it would be, to port Dropbear into our platform? We would like to integrate our CLI with the SSH. Any recommendations on using Dropbear for our platform? Appreciate sharing your experie...

...(as LLVM bytecode) on the embedded device.  LLVM would be responsible for generating (optimized, and especially vectorized for NEON) machine code directly on the embedded device and it would take care of the relocation and run-time linking duties.  This last task is very important because the RTOS (Texas Instrument's SYS/BIOS) that I'm using  does not have any dynamic linking facilities. Sharing code in the form of LLVM bytecode also seems to sidestep the complex task of setting up a cross-compiling toolchain which is something that I would prefer not to have to force my users to...

Hi All, I am trying to run a RTOS as a guest on a OMAP5432 evm and am seeing a spurious interrupt problem when programming the virtual timer interrupts. My RTOS test case uses the A15 Virtual timer to create a timer instance. Once programmed, the virtual timer interrupt is injected into my guest's virtual CPU interface as expec...

Hi Peter Thank you for your helpful comments, especially on the RPI.  Since my use case is lot simpler than compiling all of Clang, I hopefully can take your experience as a good sign. The RTOS that TI provides for the AM335x actually has pretty complete posix layer and other standard libraries.  However, I am working without any virtual memory subsystem, so no mmap.  However, I was under the impression that LLVM (ORC specifically) should be able to relocate code at any memory locatio...

...ssless FLAC and WAVE files. Is there some type of FLAC decoder “plug-in” that I can download (or save on to an SD card) that I can then “flash” onto my car’s MMI software so that it could playback FLAC files? As I understand it, the MMI employs programmable processors and runs on a Unix-like RTOS (Real Time Operating System) that can be updated using a SD card/USB/CD containing the software. MMI software update menu enables import/export settings saved as an AES (Advanced Encryption Standard) encrypted zip file. Audio files can be played back on the MMI via various drives: two SD car...

I've been chasing down a bug for a few days in some RTOS code I'm building with clang. In the end it comes down to this code: void external(void); void test(char *x) { x--; if (!x) { external(); } } When compiled for ARM with TOT clang (r183249) at -O1 or greater, no calls to 'external()' appear in the outp...

Hello all, I have successfully installed xen 3.0.2 on a dual celeron system. Linux in dom0 works fine. Now, I would like to play with the mini-os (my ultimate goal is to implement a small RTOS as guest in Xen, so mini-os looks like an ideal starting point). However, I can''t seem to get it to run as (I think) it should: It boots up, but as far as I understand the source code and the README, it should continue by printing the current time in regular intervals, which it does n...

If this were a problem with an omitted statement involving a normal variable, I'd guess you're missing a volatile qualifier. I'm not 100% sure volatile is a valid qualifier for functions, but try it. If RTOS stands for real time OS, then reading up on volatile would be a really good idea. P.S. Sorry Carl, you're going to receive this twice.

...r x86_64 and SPARC on my website at http://www.thoughtwave.net/downloads.html Some of these include libSDL support compiled in (The Solaris 10+ version), but I did not have libSDL available on my Solaris 9 machine. Some include MTOOLS 3.9.10 which is invaluable for building floppy disk images for RTOS development. The packages install in /opt/thoughtwave Have fun!

Howdy, I'm working on porting the portable version of OpenSSH to the Nucleus RTOS. So far I've had a great deal of success. However, I've run into a possible memory leak, and I'm not sure whether I need to write my own cleanup function for it or not. The xxx_kex global (defined in sshd.c) seems to not get freed. I've had difficulty finding a cleanup routine for i...

When I attempted to build Samba (v2.0.7) on a LynxOS (v3.1) box I was told that configure could determine my operating system. LynxOS, for those that don't know, is a Unix-like RTOS. It comes with a binary version of Samba, but a) it's old and b) it's not built for encrypted passwords which means I can't access it from WinNT. Can anyone advise me on what it would take to build Samba on LynxOS? Thank you. *** Steve Snyder ***

...test(char * volatile x) It works, but that's because I'm hamstringing the optimizers. I don't really see how that has anything to do with the question, though. If I change the signature to: void test(int x) It works too... what's special about 'char *'? > If RTOS stands for real time OS, then reading up on volatile would be a really good idea. I'm familiar with 'volatile' semantics, thanks. > P.S. Sorry Carl, you're going to receive this twice. I forget to CC the list. No problem. -- Carl

...ot take advantage of it? I've also heard it said, something along the lines of: "If you have to reboot, your server isn't set up correctly" to which I say piffle. Even NASA has rebooted the Mars probes after they land and I understand that they run VXWorks, incidentally, the same RTOS that my Mitel 3300 uses, and *even Mitel* recommends periodic reboots, which we duly cron every night, 2 AM. 24/7/365 installs aside, is there a reason why reboots seem to be frowned upon? Again, not trolling, just curious.

Hi All, Im a newbie here, and im sorry if im repeating the question. Im trying to compile samba 2.2.5 on QNX RTOS 6.2.0 x86pc. I am getting the following error. Compiling printing/print_generic.c Compiling printing/lpq_parse.c Compiling printing/load.c Compiling profile/profile.c profile/profile.c: In function `profile_setup': profile/profile.c:93: storage size of `shm_ds' isn't known profile/prof...

...ome to me with questions, I hedge my answers, and I don't like to do that. Here is their inquery in a nutshell. 1) The filesystem is on a battery backed up solid state device. 2) they do not care about the time necessary for recovery and avoiding corruption is paramount. 3) OS is a non-RTOS 4) The power just went out, you have 20 milliseconds..... How can corruption be avoided in this case? CAN it be avoided? If not, under what type of circumstances would the filesystem become corrupt (so we can mitigate these circumstances)? Thanks very much.
