Getting Started#

Step 1: Connect your hardware#

Connect the serial cable to the serial port of the Renesas SH7785 EDOSK and to a free serial port on the host machine (e.g. ser1 on a Neutrino host).

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.

Step 2: Build the BSP#

Step 3: Transfer the OS image to the target#

There are two different ways that you can boot the board:

Step 3A: Using ETS to Program the Combined IPL and OS Image to Flash Bank B#

To program the combined IPL and OS image ipl-ifs-edosk7780.bin into flash, using the ETS Monitor, do the following:

1. Configure the ETS Monitor as follows, substituting your own IP addresses for server and board:

       TFTP Bootloader Main Menu
          1. Boot from network
          2. Boot from flash
          3. Boot from FAT32 format MMC card
          4. Load program into flash
          5. Display configuration
          6. Change configuration
        Command:> 6
        Setup TFTP Bootloader Configuration:
        At any prompt press 'Enter' to leave unchanged or 'Esc' key to quit

        Use DHCP to setup network? (default=Static IP) [y/n]: n
        Enter board IP address []:
        Enter server IP address []:
        Enter kernel (/xfer/ipl-ifs-edosk7780.bin) filename:
        Download to flash Bank B? (default=Bank A) [y/n]: y
        Download file format bin/srec? [b/s]: b
        Binary load address [default=H'40010000]         :
        Load a disk image? [y/n]: n
        Setup kernel command line? [y/n]: n
        Boot option: TFTP, Flash, None(TFTP Menu)? [t/f/n]: t

        Is flash Bank A write protect switch SW4-4 = 'OFF'? [Y/N] : y

        Updating Boot Flash - Do not switch-off or disconnect until complete
        Please wait, saving the new Boot configuration...

        Successfully saved new TFTP Bootloader configuration.

           2. Boot from flash
           3. Boot from FAT32 format MMC card
           4. Load program into flash
           5. Display configuration
           6. Change configuration

         Flash: AM29GL512N (67108864 bytes)
         Sectors: 256 (262144 bytes each)
         Writing Binary to flash...
        Is the BIN image Big or Little Endian? [b/l]: l
        b 2 add A4000000

        Toggle flash bank select switch to boot from bank B
2. Remove power from the Target, and change DIP switch MISC_SW1 to the OFF position, to boot from flash bank B. When power is reapplied, the board should now boot the QNX IPL.

3. Once the IPL is loaded, you will be given two choices:

If you've followed the directions above, you can simply press any key (other than d) and the OS image in flash will boot.

If you wish to download the OS image serially, press the d key and use sendnto to download the image:

sendnto -b115200 -d/dev/ser1 ifs-edosk7780.bin

The serial port will change depending on which is connected to the target. Please see the sendnto documentation in the Utilities Reference.

Step 3B: Using ETS to download an ELF Format QNX Image Directly to Memory#

To download a QNX OS image directly to the board's memory, using the ETS TFTP loader, do the following:

1. Modify the OS image build file to generate an ELF image.

Change the original line: [virtual=shle/binary +compress] .bootstrap = {

to: [virtual=shle/elf +compress] .bootstrap = {

2. Generate the ELF image as described in the previous section. Note: The name of the resultant image will remain ifs-edosk7780.bin.

3. Apply power to the EDOSK7780.

4. The following should display in the serial console:

      4. Display System Configuration
5. Follow the instructions in the User's Manual provided by Renesas to start the TFTP Loader.

6. Setup the host system to accept tftp requests.

7. Using the instructions provided by Renesas for the TFTP Loader, load the ELF image.

Creating a flash partition#

1. Enter the following command to start the flash filesystem driver:

devf-edosk7780 -s0x0,64M


devf-edosk7780 -s0x04000000,64M

2. Erase the flash, except for the first 2 megabytes:

flashctl -p/dev/fs0 -o2M -ev

3. Format the partition:

flashctl -p/dev/fs0p0 -o2M -f

4. Slay, then restart the driver:

slay devf-edosk7780

devf-edosk7780 -s0x0,64M &


devf-edosk7780 -s0x04000000,64M

You should now have a /fs0p1 directory that you can copy files to.

Some of the 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 driver requires that the resource_seed utility is run, prior to running the driver.
