Note:
This BSP contains support for QNX Hypervisor 8.0 (and later versions supported by QNX SDP 8.0).
In order to make use of hypervisor support, it is required to install a compatible QNX Hypervisor product in your installation environment.
The Hypervisor-supported boot image does not build by default; refer to section
Build the BSPfor more details how to build the Hypervisor boot image (Makefile target "hyp")
Note:
Optional: A Power-Safe filesystem (fs-qnx6.so) filesystem may be used as a persistent file system to save your executable files and data. After system startup, you can use fdisk and mkqnx6fs utilities to create a Power-Safe filesystem.
If the BSP supports the power-safe file system and if the user doesnt speficy a partition, the system uses devf-ram NOR flash for storage.
Supported OSs
To install and use
this BSP, you must have installed the QNX Software Development Platform 8.0
