Step 9. Build the Drivers and Copy them to the Target

To ensure that you have the latest device drivers for the DT7837, it is recommended that you rebuild the DT7837 device drivers and copy the files to the target DT7837 module using the following procedure:

1. On the host computer, change to the directory where the TI SDK directory is installed. For example, if the TI SDK directory is installed under /opt, enter the following command:

# cd /opt/ti-sdk-am335x-evm-07.00.00.00

2. To clean up any automatically generated files, enter the following command:

# make -f dt78xx.mak dtmods_clean

3. Enter the following command to rebuild the drivers:

# make -f dt78xx.mak dtmods

4. Once you have rebuilt the drivers, copy the files board-support/extra-drivers/dt78xx/dt78xx.ko, board-support/extra-drivers/dt78xx/dt7837/dt7837.ko, and board-support/extra-drivers/dt78xx-usb-gadget/g_dt78xx.ko to the following directory on the DT78xx module: /lib/modules/3.12.10-dt112614+/extra/
