During the attempt repair of a controller board, I had to know if the contents of the flash memories was still intact. The only way without soldering is through the prog plug on the controller. So I made a connection interface from the prog plug on controller board to a cheap usb eprom progger. It has taken me some time to figure out everything but it works now , i could not find the plug so i had to make one. So i'm now able to read and write both flash memories .For this method, you need the files from a working controller board , because the flash files are not useful. But you can go back to old files after failed normal flash.

Very nice.  So if someone attempts a firmware upgrade and a failure occurs, rendering the controller dead, this can bring it back to life? |

Well done, dummyload. You don't have by chance the V3.12 bin files for me ?
Are you also from Belgium ?

Thanks guys.
@ Mastertech ,yes it should ,to be fair i only tried it with a non working controller board because i suspected data corruption on that board ,i read out the data from a working board ,fully erased both flash memories from the non working controller and put in the data from the working board ,still non working board same symptoms so data corruption is not the problem (reset ic was broke board never received any reset , reset line followed vcc)
I will try it with a working board ,just need some time.(and a new pair of underpants ,just kiddng)
@ Hulio ,unfortunately (i was about to ask you the same question) no this board used to have v3.12 but i did already the emergency flash so its gone, i should have wait , now also looking for it.
Ben van west vlaanderen.
So don't flash to quickly .
There are two flash memories both 1megaB , a flash file is only 1megaB. so through flashing only half off the available memorie can be changed.

Ok that is what that big connector on the controller is for.
The flash is not usefull so you can not dump to a bin file?

@ Redfox , yes the plug is for programming the flash memorie chips and also for programming the lattice chip.
A flash file is for software driven programing meaning you don't know where and how the data wil end up in the memories.
Through the plug it's hardware programming you can make a hard copy of the memories content or replace it.
So we must can read out a board that's never been flashed , then we have geniune factory data of a particular version.

I had version 3.11 on my BR909 and i flashed to Cine 9 V2.21 in order to make the projector less loud. It works without problems. I also had a dead SEOS 919 controller ( so unknown soft. version ) wich i also flashed to Cine 9 in emergensy modus ( jumper W3 installed ). It works without problems too. I knew there are two memory chips for soft. upgrade and one of them can not be overwritten without hardware flash ( probably the Lattice chip ). That's why sometimes after flashing, even if the soft. version is new, the data in the identification menu is not changed. For istance, after Case flashed his controller with Cine 9 V2.21, the identification menu stiil say SkyVision instead of Cine 9 ( projector came from a planetarium ). The strange thing is, after flashing my two controllers with the same bin. file, the one with former BR909 V3.11 is now Cine 9 V2.21 but the one that used to be broken says SEOS PRODAS V2.21. So i guess is like you mensioned, as long time is not a hardware flash, the data can be random written. I also think ( hope ) that the crucial data is well overwritten, just ID, serial number, run hours and so on can not be changed without hardware flash. However, respect for you Dummyload for doing this. Another example of perseverence, interest and will to help others, just like Mastertech. Huge steps like this helps people to raise their hobbyes to levels manufacturers never thought we can. Hell, if i had the time and hardware, i would edit the text part of the bin. file in the Dutch language. Just for fun  ?. |

2.21 Cine 9 has everything that 3.12 909 has, there is no point going that way. The SkySkan part stayed the same, but that part is where it would normally say Barco.  |

What you see is normal.  Youre better off with the Cine 9 software, it has more features. What is your reason for wanting to go to 3.12? That is what i had. |

Thanks again Hulio , but it's still basic electronic knowledge , where are the days memorie chips (and oders) were put in sockets that made it so much easier.
If a flashed board works don't worry about it , i only seek data from a non flashed board ,so we can restore proper data in a board when a flash goes wrong.
All my board's are flashed to , so only have cinemax/cine9 data.

I have some pretty new controllers (around 500 hours 2009) with V3.20 software. I have not yet seen anything different from my Cinemax 2.13 software. When I tried an older controller with 2.20 it seemed the fans spin at higher speed. So I have the impression the 3.20 software is better than the 2.20 all Seos.
I will try to set the 2.20 to 2.21 Cinemax software and hope the fans will spin less fast. For now I will not change the 3.20 software.
Oh wait one difference is that there is a zandloper (how you call that hourglass?) often on the screen.

@ Case , you are correct but it's more about the possibility to do it, the reason someone wants 909 software can be non logical.

@ Redfox , i'm very interested to make a copy of that v3.20 software.

The serial of my controllers matches the serial of the machine so I think Barco flashed those controllers on install?
