!!!! Br-EFB Firmware Updates
The firmware in an Br-EFB can easily be upgraded at any time. To update the
firmware:
1) Download the Br-EFBv3.FRM file from the
website
2) Unzip the file (if needed)
3) Place the Br-EFBv3.FRM file onto a formatted µSd/µSdHC/µSdXc flash
card
4) Power down (or disable) whatever the Br-EFB is controlling. You don’t
want your show to do anything unexpected during the update
5) While the Br-EFB is running, remove the µSd/µSdHC/µSdXc flash card it is
using
6) Replace it with the µSd/µSdHC/µSdXc flash card that holds the
Br-EFBv3.FRM file
7) The Br-EFB will update itself
8) Once the firmware update has completed, remove the µSd/µSdHC/µSdXc
flash card that has the Br-EFBv3.FRM file on it
9) Insert the the µSd/µSdHC/µSdXc flash card with your shows on it
10)Power back up (or enable) whatever the Br-EFB is controlling.
During firmware updates, the Read LED and Busy LED flash back and forth.
The first stage is comparing the Br-EFBv3.FRM file on the Sd card. It then flashes a
little slower as it reads the Br-EFBv3.FRM file in from the Sd card. It then flashes back
and forth much more quickly as it reprograms the microcontroller in the Br-EFB.
Under no circumstances remove power from the Br-EFB while firmware is being
updated. A partial firmware update may ‘brick’ the Br-EFB, and then it will need to be
returned to the factory for reprogramming.
