Hey all, Is there a simulator-type shell of VxWorks that works with windows xp?...I'm thinking something along the lines of like cygwin...I know it's kind of a backwards idea, but I'm just talking in terms of getting used to the dev environment and basic stuff that isn't particularly real-time depedant. I heard of VxSim...has anybody used this? thanks for any insights!

I am experiencing a very bizarre problem with vxWorks and I am hoping that someone might be able to offer some suggestions on where to start looking to determine the root of the problem. VxWorks is being used on a Synergy Microsystems VME SBC which is PPC based. The problem seems to arise at random times after rebuilding the OS image. For instance, by commenting out a single 'printf' stat...

My doubt is where exactly in physical me...

Hi, I'm running VxWorks Os on a MPC 8323 processor. The VxWorks timers are based on the OS ticks (several mili seconds), but I need a way to measure small time intervals of micro seconds.Is there a Real Time clock register to read, or a cotinueosly running counter register to calculate the interval time from it?

I am using a PPC750 and vxWorks. I am trying to copy a function outside of the text/data/bss segment into an unused portion of RAM and jump to it. The function to be copied contains no library calls or function calls.

Dear all, I am just curious to know why almost all commercial popular RTOS like RTLINUX,Vxworks work mainly on Micro processor instead of Microcontrollers?

Why do RTOS prefer microprocessors as compared to microco...

Anybody have any experience with the Motorola MVME-6100 singleboard computer running vxWorks? I have been porting an application, not written by me, from an older MVME-167 processor to the MVME-6100. It has been a very long hard climb... However I feel the end is near. The application involves shared memory in the A32 space as well as the A16 space. My current dilema is that the softwa...

Hi, I find that the stackpointer is pointing to 'bcopy' at the time of crash of my VxWorks application. This was found by analysing the log file and the Vxworks MAP files. On stack traceback, i find that 'bcopy' is being called by another routine (namely 'A'). I do not find 'bcopy' being called from that routine(namely 'A'). But, i find memcpy inside that routine (namely 'A'). Ques...
