Starting a SPI device driver
QNX SDP8.0SPI Framework TechnotesAPIConfiguration
Run a board-specific SPI device driver
Syntax:
The following code block shows the SPI driver generic command line options,
where XXX is a specific name to the target board:
spi-XXX [-c config_file] [-v]
Options:
- -c config_file
- The path to the SPI configuration file. The default path is /etc/system/config/spi/spi.conf.
- -v
- Increase verbosity. This overrides the verbose value in the config file.
Description:
The SPI driver runs with either:
- the default config file,
/etc/system/config/spi/spi.conf:
or:spi-XXX - a custom config file:
spi-XXX -c config_file
Example:
Let's say we want to start the SPI driver for
a Raspberry Pi with a custom config file, then we use:
spi-bcm2711 -c /etc/config/spi-bcm2711.cfgPage updated:
