I am trying to create a partition on my external flash using littlefs
Here is the line that is returning me an error
FS_LITTLEFS_DECLARE_DEFAULT_CONFIG(storage);
static struct fs_mount_t lfs_storage_mnt = {
.type = FS_LITTLEFS,
.fs_data = &storage,
//.storage_dev = (void *)FIXED_PARTITION_ID(storage_log),
.storage_dev = (void *)FLASH_AREA_ID(storage_log),
.mnt_point = "/lfs",
};
Here is the error I am receiving
r/src/main.c.obj -MF CMakeFiles/app.dir/src/main.c.obj.d -o CMakeFiles/app.dir/src/main.c.obj -c project/app/src/main.c

WHen hovering over FLASH_AREA_ID, I have this message
identifier "PM_storage_log_ID" is undefinedC/C++(20)
#define FLASH_AREA_ID(label) FIXED_PARTITION_ID(label)
Expands to:
PM_storage_log_ID
(I have basically the same error if I use FIXED_PARTITION_ID)
This is the relevant part of my dts

and this is the relevant part on my pm_static.yml
