Note: If you have a Neutrino host with a serial mouse, you may have to move the mouse to the second serial port on your host, because some terminal programs require the first serial port.
You can build a BSP OS image from the source code and the binary components contained in a BSP package.
For instructions about building a BSP OS image, please refer to the chapter Working with a BSP in the Building Embedded Systems manual.
1. On your host machine, start your favorite terminal program with these settings:
2. Start your target. You should see output similar to the following:

Welcome to QNX Neutrino trunk on a TI DRx45x EVM
#
Note: Before burning the IPL, you might want to save the first 1 MB of flash in order to save the ROM monitor.
1. Modify the build file for IPL to get the binary OS image and run `make clean all` in the BSP's images directory to create a combined IPL/OS image to use when burning the flash.
# make clean all
2. Download the ipl-ifs-drx45x.bin image to your target board, /dev/shmem/ipl-ifs-drx45x.bin.
3. Make sure the target can read the image you want to copy, and then execute the following commands in the Neutrino shell to burn the IPL-IFS images to flash:
# devf-generic -s0x20000000,64M # flashctl -p/dev/fs0 -l6M -ve # cp -V /dev/shmem/ipl-ifs-drx45x.bin /dev/fs0
4. Reboot the target. You should see output similar to the following:
Welcome to QNX Neutrino on the Texas Instruments EVMDRX45X board. Commands: Press 'S' for serial download, using the 'sendnto' utility Press 'F' to boot an OS image in flash
5. When IPL prompt come up, Either press s to transfer the OS image serially using sendnto, or press f to scan the flash for an os image.
Note: When booting serially, images larger than 6 MB won't load unless you first modify the IPL source.
You can test the OS simply by executing any shell builtin command or any command residing within the OS image (e.g. ls).
Once the initial image is running, you can update the OS image using the network and flash drivers. For sample command lines, please see the “Summary of driver commands” section.
Note: Please check the version of these release notes on the website for the most up-to-date information.
The driver command lines below are specific to the TI DRX45X EVM board.
Note: Some of the following drivers are commented out in the default buildfile. To use the drivers in the target hardware, you'll need to uncomment them in your buildfile, rebuild the image, and load the image into the board.

The graphics driver only supports the secondary digital display interface (VPSS1) with a single display output. The driver was tested with the LG Philips LB080WV3-B1 digital LCD. Using other displays might result in undesired behavior. The LCD should be connected to the DC5 connector found at the bottom of the base board.
The VPSS controller supports the following layers or “OSD windows”:
You can control the following features for all layers:
The OSD windows can support the follow features:
You can enable or configure OSD Rectangular Cursor support using drx45x.conf.
Note: Caveats:
The DRX45X EVM (J1DDR) has two memory buses (EMIFA, EMIFB). We've found that for certain graphics operations, performance is improved if the source and destination surfaces are on separate EMIFs.
1. Enter the following command to start the flash filesystem driver:
devf-generic -s0x20000000,64M
2. Erase the flash, except for the first 6 MB:
Note: Because the ROM monitor or IPL/OS image are in the first 6 megabyte of flash , you may not want to erase them. Use the -l (length) and -o (offset) options to avoid these areas.
flashctl -p/dev/fs0 -o6M -l58M -ve
3. Format the partition:
flashctl -p/dev/fs0p0 -o6M -l58M -vf
4. Slay and then restart the driver to mount the new partition:
slay devf-generic
devf-generic -s0x20000000,64MYou should now have a /fs0p0 and /fs0p1 directory automounted.
