neighboring parts. Ground is available in many places on the SVP; check the

are not sure where to find ground. You may have to remove the Orangutan SVP’s LCD to access the
bootloader line.
The Orangutan SVP’s bootloader line.
5. The Orangutan SVP will now disconnect itself from your computer and reappear as a new device called
“Pololu org06a Bootloader”.
◦ Windows 7, Vista and Linux: The driver for the bootloader will automatically be installed.
◦ Windows XP: When the “Found New Hardware Wizard” is displayed, follow steps 4–7 in
to get the driver working.
6. Once the bootloader’s drivers are properly installed, the green USB LED should be blinking in a double
heart-beat pattern, and there should be an entry for the bootloader in the “Ports (COM & LPT)” list of your
computer’s Device Manager in Windows.
7. Use a terminal program (such as
to connect to the
bootloader’s virtual serial port. In Windows, you can determine the port name of the bootloader (e.g. COM5)
by looking in the Device Manager. In Linux, you can determine the port name (e.g.
/dev/ttyACM0
) by
running
dmesg
. You can use any baud rate.
8. Type the following lower-case letters in to your terminal program to send them to the bootloader:
fwbootload
. After each letter is sent, the bootloader should echo back the upper-case version of that letter.
After you have finished typing this sequence, you should see “FWBOOTLOAD” as the output from the
bootloader in your terminal program.
9. Now send lower-case “
s
”. The bootloader will spend a few seconds erasing the current firmware, and
then it will echo back an upper-case
S
. Do not disconnect the device from the computer after this point until
the upgrade is complete.
10. Now send the contents of the downloaded firmware upgrade file to the bootloader. The firmware
upgrade file is a plain-text (ASCII) file, so you can open it in a text editor (such as notepad), copy the whole
thing, and then paste it in to your terminal program. Alternatively, Br@y Terminal has a “Send File” button
you can use.
11. While the file is being sent, the bootloader will echo back period characters (“….”). This process will
take about 5 seconds. When the firmware upgrade is complete, the bootloader should echo back a pipe
character (“|”).
12. You can now unplug your SVP and plug it back in to the computer and use the new firmware.
