I have a QPMC-1553 in a VxWorks system. The API call, BusTools_API_InitExtended, keeps returning a error code of 203 (Bad Card Number). If I use its PCI base address for argument 2 of the API call, I get a dual port ram error, and then it does a...

Installing the QPMC-1553 in a VxWorks system is a two part process:

  1. Modify the VxWorks image to configure the QPMC-1553.
  2. Install and run the API and application programs.

To modify the VxWorks image you need to change sysLib.c, config.h, and the board-specific include file that config.h includes. There is full description of these steps in the VxWorks chapter of the "BusTools/1553-API User's Manual and Hardware Installation Guide". Briefly, you need to find an unused region of memory. It needs to be at least 8 megabytes. Typically, you can use the High regions of the A32 address range on a VME SBC. Define your memory regions in config.h and the board-specific include file and add that to the sysPhysMemDesc table. You then need to add configuration code to sysHwInit in sysLib.c

Board specific include (like vm2600.h)
#if defined (INCLUDE_CONDOR_QPMC) 
#define CONDOR_PMC_MEM_ADRS    0xf0000000      /* base of Condor PMC space */
#define CONDOR_PMC_MEM_SIZE    0x1000000       /* 16 Mbytes for 2 Condor QPMC boards */
#define CONDOR_DEV0_SPACE      0x0
#define CONDOR_DEV1_SPACE      0x800000

You may need to change macros like these two.

#if defined (INCLUDE_CONDOR_PMC) || defined (INCLUDE_CONDOR_820) || defined (INCLUDE_CONDOR_MMSI) 
#define IS_VME_ADDRESS(adrs)  ( ((UINT32)(adrs) >= (UINT32)(VME_A32_MSTR_LOCAL) && 
                                 (UINT32)(adrs) = (UINT32)(VME_A24_MSTR_LOCAL) && 
                                 (UINT32)(adrs) = (UINT32)(VME_A16_MSTR_LOCAL) && 
                                 (UINT32)(adrs) = (UINT32)(VME_A32_REG_BASE)   && 
                                 (UINT32)(adrs) = (UINT32)VME_MSTR_LO_ADRS) && 
((UINT32)(adrs) = (UINT32)(PCI_MSTR_LO_ADRS)    && 
                                (UINT32)(adrs) = (UINT32)(CONDOR_PMC_MEM_ADRS) && 
                                (UINT32)(adrs) = (UINT32)PCI_MSTR_LO_ADRS) && 

sysLib.c (sysPysMemDesc)
#if defined( INCLUDE_CONDOR_QPMC )
    (void *) CONDOR_PMC_MEM_ADRS,
    (void *) CONDOR_PMC_MEM_ADRS,
sysLib.c (sysHwInit)
           int num_pmc_boards = 0;
           int index;
           static int MAX_BOARDS=2;
           static unsigned PMC_OFFSET = 0x2000000;
           UINT32 base_addr;

           int span_count = 0;
           for(index = 0;index 

Now, rebuild the VxWorks image and download it to your target. It is helpful to have the show routines included in your image. If you have these show routines, type:


You see something like the following. The QPMC-15553 is vendorID 13c6, deviceID 1553.

value = 0 = 0x0

Now type: pciHeaderShow 0,0x10,0 to display the QPMC-1553 configuration registers.

min Grant =                   0x00
max Latency =                 0x00
value = 0 = 0x0

This verifies that you have configured the QPMC-1553 with the desired base address, 0xf0000000 in this case. The exact settings depend on your system so they may vary from what is shown here. You need to consider the memory map for the specific PowerPC and any other PCI or VME boards you have installed.

Once this process is completed and verified, you are ready to download the BusTools/1553-API. You can find the pre-compiled version under the VxWorks folder in the library directory on you host platform. If you are running Tornado, you can download VXW-PMC-1553-PPC603.out or VXW-PMC-1553-PPC604.out depending on your processor type (G3 or G4).

Now, download you application software. There is a demo program, VxW_Demo the tests the installation. You can download it and see if the board initializes and runs. You'll find it under the VxWorks folder in the Examples directory. You download VxW_demo and run it by typing:
