RP2040.
We have a bunch of custom boards arriving next week. I think I remember reading somewhere that you have to recompile MicroPython if you change from the stock 2 MB flash chip. I put a 16 MB chip (W25Q128JVS) on these boards. Don't need the storage for MicroPython at all, 2MB is fine. This is there more for a future application that is likely to be written in C.
If I do have to recompile, any guidance on what might be needed to support this chip?
Thanks.
Do I need to recompile MicroPython for 16MB flash chip?
Re: Do I need to recompile MicroPython for 16MB flash chip?
Fairly sure no recompile necessary if you don't plan to use anything past the first 2MiB.
You'd need to recompile to set a new filesystem size limit if you did want to grow the filesystem.

Seen this?

Maybe, it gives a clue to the process.

Yeah, not for this application. I guess I'll find out in a few days. I'll report back with my findings.

That looks useful. Thanks.davef wrote: ↑Thu Jul 07, 2022 3:34 amSeen this?

Boards in hand now.
Nope, did not have to recompile. Of course the MicroPython file system is still sized for a 2 MB flash chip despite the installed device being 16 MB, but that's OK in this case.
