I have found the reason.

When I use external flash the flash area open id always 0, but I am using pm_static.yml external_flash is the id is 0 littlefs_storage id is 1, so #define PARTITION_NODE DT_NODELABEL(lfs1) may have some problems we can use another way and chose right lable.

lable: storage

FS_LITTLEFS_DECLARE_DEFAULT_CONFIG(storage);
static struct fs_mount_t lfs_storage_mnt = {
	.type = FS_LITTLEFS,
	.fs_data = &storage,
	.storage_dev = (void *)FLASH_AREA_ID(storage),
	.mnt_point = "/lfs",
};

You should try checking what the print gets this value from, and try making sure that this value is gotten from the correct size call from the .yml file. I'm guessing the confusion comes from both the defines are called size. One might have to be renamed to "size_2" or something along those lines.

Best regards,

Simon
