"fs_mount.c" not behaving properly to NuttX "defconfig"

PX4 Autopilot

Hi,

We have a custom board and we are trying to add support for an external SPI NAND FLASH part - MX35LF1GE4AB. We are using the Holybro Kakuteh7v2 project as reference, particularly this commit that has support for the Winbond SPI NAND FLASH part - PX4-Autopilot/boards/holybro/kakuteh7v2 at c43ef4c222f9daae58c5f57da541e787baeecac2 · PX4/PX4-Autopilot · GitHub

In “board_app_initialize” in “init.c” , the line where it calls “nx_mount”, we got an “ENOSYS” error. This indicates that neither “BDFS_SUPPORT”, “MDFS_SUPPORT” nor “NODFS_SUPPORT” were set, which they should all be automatically set according to the configurations in “nsh>defconfig”.

The “fs_mount.c” is found here: *'platforms > nuttx > NuttX > nuttx > fs > mount > fs_mount.c
*
Are we missing anything? Why is “fs_mount.c” not seeing the configurations in “nsh>defconfig”? Any idea how we can troubleshoot this?

Thanks.
