STM32CubeMX crash after generating code an reopen the IOC file

Hello STM,

This is now my second post about this issue because the first one didn't get any answers. 

I'm trying to start a Project with STM32CubeMX, and whenever I generate the code, I can't open the IOC file again. I've attached my IOC file for your information. 

Here is the error message that I get when I try to open the file:

It's not often that one sees something as useless as this message. Why do you guys even bother to show it?

Hey STM,

the post got rid of the attached file, so here is it again.

Hello @Intector 

Seems the same issue reported in this thread and it will be fixed in the next releases.

Thank you,

BR, Souhaib

Hello @Souhaib MAZHOUD 

I don't think this is the same problem. I can open the IOC file with a text editor, delete all the references to "MMTAppReg," and set "MMTAppRegionsCount=8" to "MMTAppRegionsCount=0" after which I can open the IOC file with STM32CubeMX again.

Those are the entries which need to be deleted:

Those entries have to be modified to look like this:

MMTAppRegionsCount=0
MMTConfigApplied=false

All those entries are back if one tries to change the settings in "Tools --> Memory Management."

 

I hope I'll get old enough to see the MX update with those fixes. Do you have any information on when this will be fixed?

 

Keep an eye open and try to remember:

"Always be yourself unless you can be a pirate. Then always be a pirate."
