iRBX Boot Loader Menu
iRBX maintains two firmware images (0 and 1) on CFI flash and one copy of a bootloader. See Figure
4 for the iRBX Boot Menu options.
•
Options 0-1 show which firmware version reside on the flash on spots 0 and 1.
•
Option 2 on Menu (
Edit Active Image
) allows controlling which image would be loaded by
default upon device boot up. Option 9 might be used to save a change. After reset, the
selection bar shows which image is selected for automatic load.
•
Options 3-5 allow configuring iRBX device IP addressing.
•
Options 6-7 allow configuring the TFTP Server address and pinging it to ensure the proper
connectivity.
•
Option 8 controls the filename pulled by TFTP.
•
Option 9 triggers the update on non-Active image. To place the update on another Active
Image, the Active number should be toggled by Option 2.

It is unlikely but possible that the boot loader might be corrupted. Then, direct (JTAG) flash programming
will be required.
