Garbage Display

[ctuinstra]

I'm very new to this so be kind.  I've been working on a display for CAN data.  I have the display designed and it works and while building code for the CAN and using the GPIO5 LED for testing, when I Run it, I get a garbaged display.  I have a working sample project that was provided to me as a guide, when I run it, it works fine, but when I go back to my project, part of the other project is still being displayed.  It's as if it's not fully erasing and programming everything.  I did some research and found suggestions to select Full Chip Erase, but there isn't one.

You haven't indicated if this is a custom board or a ST development board? Not even a mention of what STM32 you're using?

It could be an external loader issue? On the other project that works, did you use the same external loader parameters on your new project? Note: Some STM32 don't use an external loader but without knowing what STM32 you're using, we can't confirm.
