基于W25Q256的Littlefs无法打开大量文件

Question

**我在W25Q256上使用littlefs来管理我的文件。当我使用 Github“tests/test_files.toml”上的 Littlefs 时，它有问题。 开始时代码运行正确并且“open_return”= 0“read_return”= 7；当代码“for (int i = 0; i < MANY_FILES_N; i++)" i run to 63 it suspended and lasts for 20seconds. Then "open_return" = -2 and "read_return" = -84. When I change ".read_size" = 64, ".prog_size" = 64, the error will be quick as i run to 31. I don not konw where has the problem, maybe littlefs interrupt function, maybe w25q, maybe spi. I know littlefs is an uncommon file system. I can not use it well. **

我也有类似的问题，也找不到原因。有大神可以给点建议吗
