Software assembly (Linux + rootfs) for Micro SD boot

The manufacturer has taken care of trouble-free assembly and software start-up for your device. It offers a good BSP, which helps obtain workable binary images in a short time.

First you have to download and install Linux DVSDK using the following link. It must be version 4.02 which is equipped DM365 support. The manuals say that the host must necessarily be ubuntu 10.04. But we still had trouble transferring the installed SDK to ubuntu 12.04.

Next, under the link, we should find DLP LightCrafter DM365 DVSDK (version 4.0), download and install it. Out of the Changes subfolder with installed files, you have to copy and replace the files with the previously installed Linux DVSDK files.

The assembly is performed with the Sourcery toolchain for ARM by Mentor Graphics. You can download and install it by clicking the link. It is important to remember to add to the $PATH description the path to the toolchain prefix.

The assembly is done in steps using the commands make, make all and make components. U-boot, uImage and rootfs images are created to be used with an SD card.

Make, make all, make components

To install all this on an SD card, you can use the ready-to-use script, mksdboot_lcr.sh, located in the bin folder.

mksdboot_lcr.sh

After the completion of the script, you have to insert the card into the connector and move the switch closer to the connector.

The loading takes some more time.
