Installation steps

Set up a Diva board

You need a Diva board with a Linux kernel with Xenomai extensions, and a filesystem with relative user-space libraries.

You can download the archive TargetDiva_141015.tar.bz2 from the section Downloads of our website, under section Run-times PLC and Diva board PLC Run-time Uncompress the archive on a Unix-type filesystem.

Copy DTB on target board

Copy the file ./kernel_dtb/am335x-axel.dtb on your board. Please refer to instruction here: http://wiki.dave.eu/index.php/Booting_Linux_Kernel. Example: if you are booting from a tftp server, copy the file in the tftp publish directory and then, on your board u-boot prompt, type

setenv dtb_file am335x-axel.dtb
saveenv

Copy Linux kernel on target board

Copy the file ./kernel_dtb/uImage_axel on your board. Please refer to instruction here: http://wiki.dave.eu/index.php/Booting_Linux_Kernel. Example: if you are booting from a tftp server, copy the file in the tftp publish directory and then, on your board u-boot prompt, type
