Wow, things just got real

Update: Solved it and am way ahead of the curve. I recently accepted a tentative contract (contingent on a successful round of funding) to develop some stuff for embedded. I'm using a newer STM32 offering to do so, and I've run head first into a limitation of STM32CubeIDE and the makefiles it generates. It wants to put all my arrays into DTCM ram instead of SRAM. I only have 128KB of the former, which isn't enough to drive all the devices I have to drive. I want to put the arrays in the latter and to do so I'm told I need to generate custom .ld linker scripts which for starters I've never had to do before, and secondly i think it will blow a nuclear sized hole in my workflow. I've got to figure this out before Tuesday, and I'm not feeling good about it.

Follow the source? Who told you that? Who do they know that told them? I'd keep going down that trail as hard as possible until someone turns up that can show you an example script. Good luck!

I already figured it out. It doesn't matter who told me.. I misunderstood you. Sorry. I found an example. It matters that the information is correct. It was.

Is it possible for you to use the Flexible Memory Controller feature in the project?

I don't know if you can map the .bss segment to it, but I couldn't say for sure. Maybe you can with STM32s. They've got some pretty wild hardware support. Anyway, I solved the problem. Cube was creating an .ld file in my root project folder and I just wasn't seeing it. Soon as I edited, problem solved.

Yes, unless you can use a variable attribute, the linker script (as ugly as its syntax is) is usually the way.

I didn't realize Cube already made one for me. I just didn't see it. It was easy enough to edit.

Tell me if I'm wrong but the only thing bss segment does is zero out the area and this is done as part of the startup.

It's the area where all uninitialized data gets placed. Things like arrays.
