ROMFS on PyBoard v1.0

[paulg1]

Is it possible to have ROMFS on this board? If so, what edits do I need to make to the source files?

Thanks Andrew. An informative document.

Unfortunately, the stm32 version of vfs_rom_ioctl.c does not implement the MP_VFS_ROM_IOCTL_WRITE_COMPLETE command. Creating the missing functionality is beyond my current skill level. So, it seems that it is not possible.

That must be a mistake in my doc, romfs definitely works on stm32 port. You can probably skip over the port implementation parts and just update the linker script to say where it should be stored and the defines needed in mpconfigboard.h
