[Tetrafan]

Hi!

I am looking for firmware files for EBTS BRC PR20. After powering-up I get following message on the console:

Running from boot code area

So it looks like that firmware is faulty and maybe flash memory is also faulty but I want to start with uploading new firmware. I konw that firmware files are available with following extension: *.brc. Please help me!
