hi, I am seeking an Operating System Abstraction Layer which will easily let me port my code to Windows, Linux and VxWorks. It should preferably be free, or at least cheap. After lots of goggling, the only thing that looks anywhere near it to it is the old NASA OSAL, but that is incomplete and seems to be abandoned (even email is bouncing) . Does anyone know of anything which fits t...

I am using VxWorks 5.5 with a BSP for the 5307 Coldfire CPU, and the Diab 4.4 compiler. The problem is this: The makeSymTbl.tcl script filters symbols that do not begin with an underscore =93_=94. This removes symbols from the symbol table such as =91dbmul=92 and =91fltused=92 found in libdcc.a., libcfp.a, and/or libimpfp.a. When creating a dynamically loadable module (.out), the load...

I'm a software person that is in over my head. I have to select a 1553 interface card for a 6U cPCI chassis that has a PowerPC board running vxWorks.

I have a system based on the Freescale MPC5200B, running VxWorks, which has a strange problem. The system has a set of self tests which opens a socket server to the world. There is some PC software which opens a socket on the server for communication, and then the user on the PC can run batteries of tests on the card. The system also has a firmware uploader. It works in the opposite way ...

We (my fellow employees and I) have been working on an MPC860-based target that is not unlike some we've developed in the past except that we have added a PCMCIA slot in which we use compact flash (CF) cards. The PCMCIA section design was based on Wind River's wrMdpPro8xx reference board and, being a VxWorks shop, we used the pccardlib.c and sys8xxPcmcia.c modules from wrMdpPro8xx BSP as our ...

Hi all, I have a board with two Philips ISP1362 USB controllers. We want to use one of them in host mode and the other one in peripheral mode. We do not need to have the OTG functionality. VxWorks 6.2 does not support this chip directly, but we hope that we can modify the OHCD driver to work with the ISP1362 chip. Has anybody already tried to do this? Thanks in advance David
