spi-tools

SPI tools for the Linux kernel

This package is only a version of spidev_test.c from

Anton Vorontsov avorontsov@ru.mvista.com
MontaVista Software, Inc. with some litle improvement. It is a SPI tool for the Linux kernel.

A simple spidev tool to send read/write spi transaction. The spidev driver must be installed.

INSTALLATION

There's no configure script, so simply run "make" to build the tools, and "make install" to install them. By default, files are installed in /usr/bin but you can change this behavior by editing the Makefile file and setting prefix to wherever you want. You may change the C compiler and the compilation flags as well.

In a cross environment, you can use DESTDIR make variable to prefix the intall path. For example, do: $ make install DESTDIR=$PWD/install

If you wish to cross compile, then just set the cross compiler prefix via the CROSS_COMPILE make variable. For example, do: $ make CROSS_COMPILE=/opt/arm-2009q1/bin/arm-none-linux-gnueabi-
