Unable to load the board file

[Anonymous]

Hey everyone!

I've been working on a design for a while now, always ensuring that I had the schematics and board files both open so that any changes I make are properly tracked.

A few days ago i tried opening the project again, the schematics editor launches regularly but when the board editor tries to launch i get this warning message "no forward-/backannotation will be performed!" and then a text editor shows this error message:

"Error:

line 1, column 1: Start tag expected."

I've attached screen captures showing the messages in this post. Please help! I've spent way too much time on this project to re-do it from scratch!

I'm currently using Eagle 7.7.0, I thought the issue could be fixed by updating to 8.0 but I still get the same issue 😞

Hi sanadarida,

Greatly appreciate your participation on the Autodesk EAGLE forums, really sorry for the inconvenience.  

Seems that your original board file has become corrupt or then header has been modified.  This is not a common occurrence, but we have had previous problems with drive Defrags or Antivirus scans that will corrupt the integrity of the file.  The fastest and easiest solution here is to recover from a backup, EAGLE does create 2 forms of backup and will exist in the exact directory wherever you file is located.

.b#1 to .b#9 are backups that are added every time you click on the save command, the second backup is a timed interval backup, this backup will overwrite the previous timed backup and will have the extension .b##.

Observe the time stamp of your board backup files and rename the file with the extension .brd.  

Best Regards,

Ed

I have a similar problem but have no backup file.  Is there a way to override this error?

Hello aikjig,

I hope you're doing well. Unfortunately, there is no way to override that error. If it was a board originally made in EAGLE then you could try opening the file in a text editor and see if there's any human readable text. If it's not originally an EAGLE file then EAGLE won't be able to open it no matter what you do.

Please let me know if there's anything else I can do for you.

I am getting the same issue (first the warning, then the text editor error message exactly as above). But, the .sch file I am attempting to open is from a .zip that I am getting from another website. Would this be the same problem but on their end?

Hello @Anonymous,

I hope you're doing well. If you are downloading from github make sure to download the entire repository and not just the individual schematic and board files since that will download some html into the file.

This message never involves EAGLE's own code it's a reaction to the file that it has been given. If the file isn't an EAGLE file you will get this error. Check the website and see what tool the design was made in and then go from there.

Let me know if there's anything else I can do for you.

Best Regards,
