Cannot delete HEX file, shows as being open in Visual Studio

I have an intermittent problem. I have a project running on an ATmega2560, everything compiles, uploads and runs without error. Every 5 or so edit/compile/upload cycles appear to proceed as normal but I see the following message :

Compiling 'WSPR_Test' for 'ATmega2560 (Mega 2560) (Arduino Mega)      (mega_atmega2560)'
Program size: 59456 bytes (used 23% of a 253952 byte maximum) (3.68 secs)
Minimum Memory Usage: 3160 bytes (39% of a 8192 byte maximum)
avr-objcopy*: R_Test.ino.hex: Permission denied
 
Uploading 'WSPR_Test' to 'ATmega2560 (Mega 2560) (Arduino Mega) (mega_atmega2560)' using 'COM4'
     The upload process has finished.


Although the compile cycle runs without error, the HEX file is not being updated. It appears to be open and therefore cannot be written to. When I try to delete the .HEX file, I get the following message:

File in Use
The action can't be completed because the file is open in Microsoft Visual Studio 2002

Close the file and try again

WSPR_Test.ino.hex

I have to close down Visual Studio, delete the HEX file and then restart VS. I have done an extensive search on-line but can see no report of a similar error. I can see no setting in VM or VS that should cause this sort of problem.

Has anyone experienced a similar problem ?

It means the file is locked and can not be regenerated. Only software such as virus checker or file uploader would cause this. or are you working on a remote drive?

No virus checker is running, and I'm not working with a remote drive. If I try to delete the file while VS is running, I'm told file is in use. Once I close VS, I can delete the file.

Then it's possible whatever uploader is being used it hanging onto the file. Please follow the guide in yellow above. Thanks

Thanks for the emailed output. It's potentially and issue with the build or upload tools of arduino AVR 1.8.4. Trying using board manager to update to the latest avr.

If that doesn't rosolve then switch on vmicro>general>upload verbose and send the output again after upload.

All Arduino upload software presumably part of Arduino IDE. Currently using following software:

Arduino IDE and associated files  version: 2.0.3

VS version: Microsoft Visual Studio Community 2022 (64-bit) – Current Version 17.4.5

VM Version: Release 22.11.28.15

Dumps with file locked and not locked emailed to you as per request. Currently trying to reproduce error using just Arduino IDE, so far all seems OK

Update...

Repeatedly built and uploaded using Arduino IDE - No problems.

Using VS - Problem still occurs when Cleaning and Re-building project without uploading to processor. Presumably this eliminates any problems with the uploading software.

I'm also getting the same random error.  Installed the latest version and made sure the virus check was off.  Hit the compile button and still got...

avr-objcopy*: C:\Users\Blair\AppData\Local\Temp\VMBuilds\Sketch1\uno\Release\Sketch1.ino.hex: Permission denied

Thanks for adding to the thread.

Can you enable the settings shown at the top of the page and attach the complete Micro Build Output for us to review?

Does this happen for you every compilation or is it an intermittent error as other users have experienced?

Logs sent via email.

The first time it always works after that, sometimes it works sometimes it doesn't, there doesn't seem to be a pattern.

Thanks for the logs and the update.

Can you add a local board.txt file to the project (vMicro > Add Code > Add Local board.txt) and put the below entry in, and save the file:
bootloader.file=

Then ensure the file is unlocked (restart VS) and then try recompiling the project a number of times to see if the issue still presents itself it would be very helpful.

Ok... I reread the message again and came to the conclusion I was to add board.txt to the solution and add the entry  'bootloader.file=' to it.

Ran it multiple times, only managed to make it fail once.

Thanks for all the feedback. Please install the LATEST from again. Hopefully that resolves.

Delete the local board.txt that was added for testing. It will cause confusion.

I've downloaded and installed the latest version - 2.2023.0220 Minor 3

I've given it a fairly good thrashing  (it seemed to enjoy it  Smiley) and so far it seems to release the HEX file every time. 

I've had to be off-air the past week so will be getting into some heavy compiling over the next few days. I'll let you know how it goes, one way or another in a day or two. Many thanks for your help, and to all others who made a contribution.

Hi

Spent a long night with many, many edit/compile/upload cycles and I'm happy to say the problem seems to have gone away which makes me a very happy little Vegimite Smiley

Thanks lads
