The makefile dt78xx.mak is provided to build the Linux kernel with DT78xx-specific customizations, device tree, loadable kernel modules (LKMs), and examples.
The makefile has the following usage:
make -f dt78xx.mak [params] <target>
The params argument is optional.
Note that if the Data Translation software is installed under the TI SDK
directory, then the default values of all parameters in this makefile
do not need to be overridden. Possible values for params
are as follows:
Params |
Description |
|---|---|
RULES_DIR |
Complete path to directory where the TI SDK is installed . |
DT78xx_INSTALL_DIR |
Complete path to directory where the DT78xx software is installed |
Possible values for the targets
argument are as follows:
Target |
Description |
|---|---|
all |
Builds Linux kernel and all loadable kernel modules (LKM), DT78xx-specific LKMs, and examples |
clean |
Cleans all files generated by the target all |
linux |
Builds the linux kernel and all LKMs |
linux_clean |
Cleans all files generated by the target linux |
dtmods |
All DT78xx-specific LKMs. |
dtmods_clean |
Cleans all files generated by the target dtmods. |
dtexamples |
Builds all DT78xx examples. |
dtexamples_clean |
Cleans all files generated by the target dtexamples. |
For example, if the TI SDK is installed in the /opt/ti-sdk-am335x-evm-07.00.00.00 directory, use this command to build the linux kernel, all the LKMs, DT7816-specific LKMs, and examples:
# cd /opt/ti-sdk-am335x-evm-07.00.00.00
# make -f dt78xx.mak all
