The tables below depict the memory layout for the image and for the flash.
| Item | Address |
|---|---|
| OS image loaded at: | 0x88010000 |
| OS image begins execution at: | 0x88012ba0 |
| Flash base address (Bank A SW4 - 1 ON) | 0x00000000 |
| Flash base address (Bank B SW4 - 1 ON) | 0x04000000 |
| Serial base address (SCIF 0) | 0xFFE00000 (IRQ: 0x2018) |
| Serial base address (SCIF 1) | 0xFFE10000 (IRQ: 0x203C) |
| Ethernet base address | 0x15800000 (IRQ: 6) |
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.
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:

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
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 edosk7780.build 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:

Command:>
6. Setup the host system to accept tftp requests.
7. Using the instructions provided by Renesas for the TFTP Loader, load the ELF image.
1. Enter the following command to start the flash filesystem driver:
devf-edosk7780 -s0x0,64M
or:
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 &
or:
devf-edosk7780 -s0x04000000,64M
You should now have a /fs0p1 directory that you can copy files to.
The following table summarizes the commands to launch the various drivers.

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.
