Hi @acassis, the execution weirdly stops in-between execution it seems. I am not too knowledgeable about the memory limits in the simulator. For me the stack trace for mkfatfs on `/dev/nand` sort of went like this: [mkfatfs.c:mkfatfs():L326](https://github.com/apache/nuttx-apps/blob/bc68ce993b1ec385cb7d8f11b5e8fca96d53f3be/fsutils/mkfatfs/mkfatfs.c#L326) [fs_open.c:open():L453](https://github.com/apache/nuttx/blob/master/fs/vfs/fs_open.c#L453) [fs_open.c:nx_vopen():L300](https://github.com/apache/nuttx/blob/master/fs/vfs/fs_open.c#L300) [fs_open.c:file_vopen():L199](https://github.com/apache/nuttx/blob/master/fs/vfs/fs_open.c#L199) [fs_blockproxy.c:block_proxy():L167](https://github.com/apache/nuttx/blob/master/fs/driver/fs_blockproxy.c#L167) [bchdev_register.c:bchdev_register():L61](https://github.com/apache/nuttx/blob/master/drivers/bch/bchdev_register.c#L61) [bchlib_setup.c:bchlib_setup():L75](https://github.com/apache/nuttx/blob/master/drivers/bch/bchlib_setup.c#L75) [fs_openblockdriver.c:open_blockdriver():L86](https://github.com/apache/nuttx/blob/master/fs/driver/fs_openblockdriver.c#L86) [fs_mtdproxy.c:mtd_proxy():L164](https://github.com/apache/nuttx/blob/master/fs/driver/fs_mtdproxy.c#L164) And in ftl.c, it crashes in between [this area](https://github.com/apache/nuttx/blob/master/drivers/mtd/ftl.c#L839-L864). My config: - Disabled: - `CONFIG_FTL_READAHEAD` - `CONFIG_FTL_WRITEBUFFER` Thus `FTL_HAVE_RWBUFFER` is also disabled. So the entire area has nothing to crash on, and I think, like @acassis said, it might be due to a memory limit. I am not sure what can prevent this, and I need help on this. Both `mkfatfs` and `echo` commands provided by @laoniaokkk stop at this point. `nand` (the device simulator) relies heavily on memory. Currently, the entire memory is allocated in an entire contiguous chunk, which _might_ be a cause. Of course this can be changed to be more lazy in nature. The sim device is still experimental so a lot of features are missing or might not work in certain circumstances. It has been tested mostly by using littlefs.
