Driver Commands

Some of the drivers are commented out in the buildfile. To use these drivers on the target hardware, you may need to uncomment them in the buildfile, rebuild the image, and then load the image onto the board.

The order that the drivers are started in the provided buildfile is one way to start them. The order that you start the drivers is completely customizable and is often specific to your system requirements. For example, if you need an audible sound to play immediately, you must start the audio driver earlier than other drivers. It's important to recognize that the order you choose impacts the boot time.

Note:

Some drivers depend on other drivers, so it's sometimes necessary to start them in a specific order.

For more information on best practices for building an embedded system and optimizing boot times for your system, see the Building Embedded Systems and the Boot Optimization guides in the QNX Software Development Platform 8.0 documentation.
For more information about the drivers and commands listed here, see the QNX OS Utilities Reference. This chapter provides information about BSP-specific options for any of the commands and drivers that aren't described in the Utilities Reference. In some cases, the driver or command is specific to this BSP, in which case, you'll find the information in the BSP-specific Drivers and Utilities chapter.

Here's the list of drivers available for this board and the order in which they appear in the buildfile:

CAN
Inter-integrated Circuit (I2C)
Network
PCI
QSPI NOR flash
SD/MMC
Serial (UART)
SPI
Startup
USB 2.0 Host
Watchdog

The following BSP-specific utilities or libraries are available in the buildfile, but aren't explicitly run in the buildfile:
