QNX Neutrino RTOS Hosts

This chapter includes the following:

Note: If you've already installed an evaluation version of QNX SDP 6.5.0, and you've purchased and received a commercial QNX license or you've received an evaluation extension license, please go to Commercializing your evaluation software,” below.

Before you start

System requirements

Minimum Recommended
Processor 2 GHz or more Intel Pentium 4 2 GHz or more Intel Pentium 4
RAM 512 MB 1 GB
Disk space 3.0 GB 3.5 GB
Monitor 1024×768 1280×1024

Caution: Some x86 systems can run in System Management Mode (SMM), where the BIOS installs special code that runs when a System Management Interrupt (SMI) occurs. SMI interrupts may be generated by the motherboard or peripheral hardware, and can't be masked by the operating system. When SMM is entered, normal operations — including the OS — are suspended, and the SMI handler runs at a high priority. Avoid using systems where SMM can't be disabled, because it can destroy QNX Neutrino's realtime performance. The OS can't do anything about the delays that SMM introduces, nor can the OS even detect that the system has entered SMM.

You can also install the QNX Neutrino RTOS as a virtual machine on VMware Workstation 6.5 or 7.0, VMWare Player 3.0, and Microsoft VirtualPC 2007. To ensure that VMware is supported for your host, search the compatibility guide located at http://www.vmware.com/resources/compatibility/search.php. If you find problems with any virtualization environment, please post your findings in one of the forums in our Foundry27 community website.

QNX SDP 6.5.0 SP1 requires 250 MB of disk space; the version for x86 targets requires 220 MB.

BIOS settings

We recommend you use the following BIOS settings:

Installing QNX SDP 6.5.0 SP1

To install QNX SDP 6.5.0 SP1, do the following:

  1. Log in as root.
  2. Log in to your myQNX account on our website, and then go to the Download area.
  3. Download the SP1 package, qnxsdp-6.5.0SP1-nnnnnnnnnnn-nto.sh, where nnnnnnnnnnn is the 11-digit build number. The package is a shell script.
  4. Run chmod to make the script executable. For example:
    chmod a+x qnxsdp-6.5.0SP1-20123030202-nto.sh
  5. Run the script at the system prompt. For example:
  6. Follow the instructions on your screen.

Errors while booting

If an error occurs while you're booting your system, the boot loader may display the error messages listed below, depending on the type of partition that you chose.

For a Power-Safe (fs-qnx6.so) filesystem, the boot loader may display the following messages:

Unsupported BIOS
The BIOS doesn't support INT13 LBA extensions.
Missing OS Image
The filesystem isn't an fs-qnx6 one, or the .boot directory is empty.
Invalid OS Image
The selected file isn't an x86 startup boot image.
Disk Read Error
A physical I/O error occurred while reading the disk.
Ram Error
A physical RAM error occurred while copying the boot image.

If an error occurs when you boot from a QNX 4 filesystem, the boot loader displays one of the following characters, and then the boot process halts:

No OS signature was found.
D or ?
An error occurred reading the disk.

For more information, see the Controlling How Neutrino Starts chapter of the QNX Neutrino User's Guide.

Activating QNX SDP

The QNX Momentics Tool Suite and certain related products require activation. If you don't activate the product within the specified timeframe, the product will cease to function until you activate it. No personal data is transferred during the activation process. If your license key indicates that you have a “named user” license, the activation requires that you provide an email address.

Activating automatically

If your development host is connected to the Internet, you can activate QNX SDP automatically.

Activating manually

if your machine isn't connected to the Internet, you must activate your software manually from a machine that is, by doing the following:

  1. In the QNX SDP Activation dialog, click Activate Manually.

    The Manual Activation dialog appears with an activate-prompt key. This dialog has a button that you can use to save the activate-prompt key in a file, /etc/qnx/license/activate_prompt_key.txt. Using this file eliminates the need to retype the key, which can be error-prone.

  2. Transfer the activate-prompt key to the machine that's connected to the Internet.
  3. Go to our website, www.qnx.com, log in to your myQNX account, and choose Manual Product Activation.
  4. Enter the activate-prompt key into the form that appears, and then click Generate Response Key. This will return an activate-response key.
  5. Copy the activate-response key and paste it in a file.
  6. Transfer the file into /etc/qnx/license/activate_response_key.txt on your QNX SDP development host.
  7. If you closed the QNX SDP Activation dialog, open it again by selecting Configure-->Activate License from the Launch menu, or by entering the following at a terminal prompt:
    /etc/qnx/bin/qnxactivate -a
  8. Choose Activate Manually, and use the Load Response from File button to load the activate-response key, and then click Activate.

If you choose not to activate at the time of installation, you can activate later by selecting Configure-->Activate License from the Launch menu, or by entering the following at a terminal prompt:

/etc/qnx/bin/qnxactivate -a

Commercializing your evaluation software

If you installed an evaluation copy of QNX SDP 6.5.0, and you've now received a commercial QNX license, do the following to add your commercial license:

  1. Choose Configure-->Add License from the Launch menu.
  2. Enter the license key.
  3. After entering the license key, you'll be presented with the appropriate license agreement. You'll need to accept it in order to successfully add a license.

Uninstalling QNX SDP 6.5.0 and SP1

  • It isn't possible to uninstall just QNX SDP 6.5.0 SP1.
  • You should uninstall QNX products in the reverse order in which you installed them. To determine this order, use a command like this:

    ls -lt `find base_directory -name "*uninstall*.sh"`

    where base_directory is where you installed the QNX Software Development Platform.

To completely uninstall QNX SDP, simply erase or delete the partition you installed it in.

Determining your base directory

To determine the base directory for QNX SDP, open a command shell and use the qconfig command. For example:

$ qconfig
QNX Installations

  Installation Name: QNX Software Development Platform 6.5.0
            Version: 6.5.0
     Base Directory: /usr/qnx650/
           QNX_HOST: /usr/qnx650/host/qnx6/x86/
         QNX_TARGET: /usr/qnx650/target/qnx6/

The base directory in this example is /usr/qnx650/, but it could be different on your machine, depending on where you installed QNX SDP.
