openMV porting problem on NUCLEO_F767ZI

Hello everyone, as subject said, I get .rodata problem when porting on NUCLEO_F767ZI.

Here's a screenshot:

I know openMV didn't support nucleo boards, but I think I can ask some question about compile.
How can I fix this problem?

Thank you so much,
Eric

Re: OpenMV porting on own board

Um, so, if you are doing your own custom board we'd expect you to be a complete expert in what you are doing. Adding SRAM is hard. We will be releasing a camera with SRAM support soon. But, otherwise, you're on your own. I can't tell you why the USB is broken either. All this stuff is very hard. Th...
