4. Linux Applications Development
This section focuses on application development based on embedded Linux, the
following examples provided by MYIR Tech demonstrate how to take the control of
some commonly used peripheral devices through Linux applications. The source
code of these examples is located at
04-Linux_Source\Examples
of our release
package. Please follow the instructions provided in the readme file to set the
environment variables, compile the source code and install the binary files into MYD-
AM335X series development board.
$ cd <WORKDIR>/Examples/
Make sure the following environment variables are right.
$ export PATH=$PATH:<WORKDIR>/Toolchain/
gcc-linaro-5.3-2016.02-x86_64_arm-linux-gnueabihf/bin
$ export ARCH=arm
$ export CROSS_COMPILE=arm-linux-gnueabihf-
After building Buildroot, a cross compile toolchain has been created at
myir-
buildroot/output/host/usr/bin
, it can be used here by setting the environment
variables instead of the above.
$ export ARCH=arm
$ export CROSS_COMPILE=arm-myir-linux-gnueabihf-
$ export PATH=$PATH:<WORKDIR>/Filesystem/myir-buildroot/output/host/usr/bin
$ export PATH=$PATH:<WORKDIR>/Filesystem/myir-buildroot/output/host/usr/sbin
Customers could build examples all in one step:
$ cd <WORKDIR>/Examples/
$ make OPTION=MYD-AM335X-SERIES
Or build the examples respectively:
$ cd <WORKDIR>/Examples/<APP_DIR>
