assertion "lfs->cfg->cache_size % lfs->cfg->read_size == 0" in function lfs_init #890

assertion "lfs->cfg->cache_size % lfs->cfg->read_size == 0" in function lfs_init. The value of cache_size at the assertion is 2048 and the value of read_size is 2147672080. The value of read_size is obviously wrong. Has anyone experienced this problem?

Hi @zhujhhh, littlefs doesn't modify lfs->cfg->read_size, so I have to assume the issue is above littlefs.

Do you use littlefs as a part of another library? If so you may need to raise an issue there for uninitialized configuration of littlefs.

If you are declaring struct lfs_config yourself, are you not setting read_size? read_size=1 is valid and common for NOR flash devices.
