|If you've already installed an evaluation version of QNX SDP 6.5.0, and you've purchased and received a commercial QNX license, please go to “Commercializing your evaluation software,” below.|
|Processor||2 GHz or more Intel Pentium 4||2 GHz or more Intel Pentium 4|
|RAM||512 MB||1 GB|
|Disk space||2.2 GB||2.7 GB|
|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. If you find problems with any virtualization environment, please post your findings in one of the forums in our Foundry27 community website.
We recommend you use the following BIOS settings:
To install QNX SDP 6.5.0, do the following:
The default is 179. If there's already a partition of the type you chose, you're given the choice of deleting a partition or choosing another type.
The installer will also ask if you wish to install a package of GNU Public License programs, such as tar and sed. We recommend that you do so for development machines.
| If your EIDE doesn't support DMA:
If you have more than one partition on your disk, choose the one you installed QNX Neutrino in. Choose the appropriate boot loader. If you don't choose a partition or boot loader, the system uses the default ones.
|When you start a QNX Neutrino system for the first time, it chooses a “safe” graphics driver (devg-svga.so or devg-vesabios.so, depending on the installed chipset). However, these generic VESA BIOS and SVGA drivers can negatively impact the timing of a system and affect realtime operations. We recommended you use an accelerated driver instead, if at all possible.|
For more information about booting, see the Controlling How Neutrino Starts chapter of the QNX Neutrino User's Guide.
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 development host is connected to the Internet, you can activate QNX SDP automatically.
if your machine isn't connected to the Internet, you must activate your software manually from a machine that is, by doing the following:
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. This can eliminate the need to retype the key, which can be error-prone.
If you choose not to activate at the time of installation, you can activate later by selectingfrom the Launch menu, or by entering the following at a terminal prompt:
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:
The Neutrino boot process can dynamically add block I/O (i.e. disk) drivers, letting you boot on systems with newer controllers. The mechanism is simple and not proprietary to QNX Software Systems, so third parties can offer enhanced block drivers without any intervention on our part. For more information, see “Updating disk drivers” in the Controlling How Neutrino Starts chapter of the Neutrino User's Guide.
|You should uninstall QNX products in the reverse order in which you
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.
If you want to uninstall QNX SDP completely, simply erase or delete the partition you installed it in.
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.
