QNX® Momentics® 6.3.0 Intel DBPXA270DP BSP 1.0.0 Release Notes

QNX® Momentics® 6.3.0

Date of this edition: May 22, 2009

Target OS: QNX^® Neutrino^® 6.3.0 SP1

Host OS: Microsoft Windows XP SP1 or SP2; Microsoft Windows 2000 SP4; Sun Solaris 7/8; QNX^® Neutrino^® 6.3.0 SP1; Linux (Red Hat 8/9)

You need to have installed the QNX Momentics 6.3.0 SP1 before installing this BSP.
For information on installing this BSP, see the installation note.
If you install SP1, you should also install the latest version of the QNX Momentics Character Driver Development Kit (DDK), if you installed an earlier version of it. Significant changes have been made to this DDK; please see the Character DDK Release Notes.

Intel DBPXA270DB Board Support Package readme (HTML)

The flash filesystem library is included in the separately available Flash Filesystem & Embedding Technology Development Kit (TDK).

Each BSP guide contains board-specific information and instructions on building an OS image for that particular board.

The procedure for building BSPs has changed since QNX Momentics 6.2.1. For instance, you must now run the . ./setenv.sh script before compiling your BSP source. For details, see the chapter “Working with a BSP” in the Building Embedded Systems manual (in the Documentation Roadmap page under the QNX Neutrino RTOS section).

Location of source and documentation

When you install BSPs, you'll find the source code in $QNX_TARGET\usr\src\archives\qnx\ on Windows, and in $QNX_TARGET/usr/src/archives/qnx/ on QNX Neutrino and Linux.

You can read the documentation (including release notes) in the Integrated Development Environment's help system on all host OSs; on self-hosted QNX Neutrino systems, you can also read it in the Photon helpviewer, or you can use a web browser to display:

${QNX_TARGET}/usr/help/product/momentics/bookset.html

This “roadmap” page contains links to the various HTML booksets that accompany the OS (e.g. System Architecture, QNX Neutrino Programmer's Guide, Library Reference, Utilities Reference, etc.).

Binaries, buildfiles, IPLs, and other files

Depending on the particular BSP and type of driver, you'll find the files in these locations:

Windows hosts

File	Location
Buildfile	`$QNX_TARGET\cpu\boot\build`
IPL and/or startup	`$QNX_TARGET\cpu\boot\sys`
“`sbin`” drivers (serial, flash, block, PCI, PCMCIA, USB)	`$QNX_TARGET\cpu\sbin`
“`dll`” drivers (audio, graphics, network)	`$QNX_TARGET/cpu/lib/dll`

QNX Neutrino, Linux, and Solaris hosts

File	Location
Buildfile	`$QNX_TARGET/cpu/boot/build`
IPL and/or startup	`$QNX_TARGET/cpu/boot/sys`
“`sbin`” drivers (serial, flash, block, PCI, PCMCIA, USB)	`$QNX_TARGET/cpu/sbin`
“`dll`” drivers (audio, graphics, network)	`$QNX_TARGET/cpu/lib/dll`

Known issues for this BSP

A comment in the DBPXA270DP buildfile says the GPIO interrupts are 0x100–0x118; this should actually be 0x100–0x176. (Ref# 29475)
In Microsoft Windows, certain programs (e.g. Norton Ghost) add directories inside double quotation marks (e.g. ...;"c:\Program Files\Norton Ghost\";...) to your PATH environment variable. This causes the Cygwin spawn() function to fail, which in turn causes cp to fail when called by ln-w. (Ref# 20046)
Workaround: Modify your PATH environment variable and remove any quotation marks.
To build the BSP from the command line, you need to extract the source code from the zip file. In Microsoft Windows, make sure you place the source code in a directory that doesn't contain any spaces in its name.
In those instances where the the ROM monitor's MAC address is different from the one you pass in when running io-net, the host can cache the ROM monitor's address. This can result in a loss of connectivity.
Workaround: If you need to specify a MAC address to io-net, we recommend that you use the same MAC address that the ROM monitor uses. This will ensure that if the host caches the ROM monitor's MAC address, you'll still be able to communicate with the target. Otherwise you might need to delete the target's arp entry on your host.
Simply uncommenting the io-graphics line in the buildfile isn't enough to run Photon on the target; this line shows how to run the graphics driver only. For more information on embedding Photon on your board, see the Photon in Embedded Systems appendix of the Photon Programmer's Guide.
To test or evaluate Photon on your target before embedding it you could make the Photon environment accessible to the target by simply mounting your host environment into the target. You'll need to use an NFS or CIFS client on the target depending on the type of server running on your host platform. This example shows how to create a basic Photon configuration using an NFS client.
1. Uncomment the following sections from the build file: network, usb and graphics
2. Add the following at the end of the network section:
```
     fs-nfs3 10.0.0.1:$QNX_TARGET/cpu/ /
             10.0.0.1:$QNX_TARGET/etc /etc
             10.0.0.1:$QNX_TARGET/usr/photon /usr/photon &
     waitfor /usr/bin
     waitfor /usr/photon
     waitfor /etc

     Where 10.0.0.1 is the server IP address
   
```
  The first three lines of the fs-nfs command comprise one command.
3. You can now run the Photon drivers.
  To run the graphics driver:
```
      /usr/photon/bin/Photon &
      waitfor /dev/photon
      /usr/photon/bin/io-graphics -d...
     
```
  (See the “Devices supported” chapter in the BSP documentation for details on the graphics driver options).
  If your board doesn't have a specific Input driver (See the “Devices supported” chapter in the BSP documentation for details) but it has USB support, to use a USB mouse and keyboard you could run:
```
      /sbin/io-hid -dusb
      /usr/photon/bin/devi-hid kbd mouse &
   
```
  Otherwise run the Input driver as described in the BSP documentation.
If you specify the -d and -p options for io-graphics, you must put the -d option before the -p, or else io-graphics fails. (Ref# 22670)
When you install several BSPs that share common files, you'll be prompted to overwrite the existing files. We recommend that you backup the existing files before you overwrite them. Uninstalling any BSP that shares that file will currently remove the common file. You'll need to restore the backup after you uninstall any BSP that shared the file(s). (Ref# 22922)
