Documentation

• Freescale i.MX31 Board Support Package readme (HTML)

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

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.).

• USB devices connected to the USB port1 (i.e. Full Speed:USB 1.0 compliant) through a USB hub (2.0 or 1.0 compliant) won't be detected on a RevC of the Freescale i.MX31 ADS board. If connected to a RevD most devices will be detected but a low speed device such as a USB mouse won't be detected. However If the low speed device is connected directly to this USB port it will be detected. (Ref# 41759).

  Workaround: Use the USB Port2 on either Revc or RevD boards (i.e. High Speed port: USB 2.0 compliant) and every device will be detected properly or do not use a hub to connect USB devices on the USB port1.

• 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.

• Some warnings may be displayed when compiling this BSP with one or both supported compilers. These warnings are benign and do not affect the functionality of the resulting binaries.

• 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.

• 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)
