Driver Commands

The tables list any additional libraries and binaries that are required. Default required libraries, such as libc.so and libgcc_s.so.1 aren't listed, but should be included in your buildfile.

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 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 the requirements of your system. 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 because of these dependencies. For example, in the provided buildfile, the USB driver is started before the mass storage drivers because they rely on it.

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.

Startup


Device	Startup
Command	startup-xzynq-kv260 -v
Required binaries	startup-xzynq-kv260
Required libraries
Source location	$BSP_ROOT_DIR/src/hardware/startup/boards/xzynq/kv260

In addition to the common options available for the startup-* command as described in the Utilities Reference in the QNX SDP 8.0 documentation, this driver supports these options:

-a <AXI INTC base address>,<GIC IRQ #>[,<GIC IRQ trigger mode>]

Configure the AXI INTC controller(s) present in the PL image. <GIC IRQ trigger mode> should be 0 for level-triggered (the default) or 1 for edge-triggered. A maximum of 4 INTC controllers can be configured.

Ex:

Configure an INTC with base address 0x80042000 connected to level-triggered GIC IRQ 141. Also configure a second INTC with base address 0x80043000 connected to edge-triggered GIC IRQ 142.
