Cobra ODE User Manual v2.0

The update should takes a couple of seconds to finish. The LED should flash very briefly,
and appear purple for a second, indicating that the update is in progress, then it becomes
solid red to indicate there is no manager or database on the USB stick, or green if the fat32
drive you're using also contains the manager and cobra.db file. Once it is done, then you
can turn on the console and enjoy the new features provided by the firmware upgrade.
*IMPORTANT* Please note that your device may be damaged if there is a loss of
power during the update of the BOOTLOADER. Make sure you connect your power
cable correctly and do not disconnect it while the update is in progress. There are no
risks however during a normal update of the MCU firmware, and BOOTLOADER
updates will be very rare.

FPGA firmware update for Cobra ODE v3.XX to v4.XX
Occasionally, an update to the ODE's FPGA images will be made available. You can
download the latest FPGA images from the »Downloads« section of our website on
http://www.cobra-ode.com
. On v3.00, v4.20 and v4.30 boards, there are three FPGA chips
each requiring their own image. In order to update the FPGA images you must have
updated to at least the BOOTLOADER 1.3 before attempting the update.
Once an update has been released, download the FPGA images for your board.
It is very important to use the correct FPGA images for your Cobra ODE Board. The
board version will be printed on the PCB of the Cobra ODE.
4.3.1
Correct update sequence
For the update to be successful. Please follow this sequence when updating. Firstly you
have to update your BOOTLOADER (ldr.rom) to the latest version (
if that is necessary)
!
After that you have to update you MCU (mcu.rom) to the latest version (
if a newer
version is available and needed for this update
). When both the BOOTLOADE and
MCU are updated then you update FPGA1 (fpga1.dat) and then FPGA3 (fpga3.dat or
fpga2.dat if that is necessary).
