Appendix B: Firmware Upgrades

 

1)

 

Obtain the latest firmware update from 

www.skookumrobotics.com

 

2)

 

Unzip the firmware file from the compressed archive file using WinZip 

(or a similar program) to a convenient directory on your PC. 

3)

 

Connect  the  SK720  unit  to  your  PC  with  a  USB  cable  and  ensure  that 

the status indicator in the upper left corner of the GUI shows green and 
says “connected”. 

4)

 

Select the “Update SK-720 Firmware” option under the “Utility” menu.  

5)

 

A  window  will  appear  allowing  you  to  select  the  location  of  the  new 

firmware file. Find the file in the convenient directory that you chose at 
step 2 above and click the “Open” button. 

6)

 

The  dialog  box  shown  below  will  appear  next.  Click  the  OK  button  to 

begin  the  firmware  update  process.  Click  the  cancel  button  to  quit 
without updating your SK720. 

 

7)

 

There will be a 15 second pause before the update process begins. The 

SK720’s LED will then flash green and red for about one minute while 
the  unit  writes  the  new  firmware  to  its  internal  memory.  During  this 
time, the status indicator in the  main GUI screen  will be light blue and 
will say “Busy”. 

8)

 

If the LEDs did not flash green and red after the 15 second pause, then 

the firmware file may have been corrupted. Try steps 1 through 7 again 
or email technical support at Skookum Robotics. 

WARNING:

  Do  not  disturb  the  SK720  while  the  firmware  is  updating.  The 

firmware  update  process  may  fail  if  you  do,  making  the  unit  into  a 
paperweight.  Your  SK720  would  then  need  to  be  returned  to  Skookum 
Robotics for servicing.
