How to use NAND Flash device simulator

I add NAND simulation under sim/nsh configuration, when 'nand' is executed, the ‘/dev/nand‘ device will be generated, but when using "mkfatfs /dev/nand" or "echo hello > /dev/nand", some errors will be generated and the program will be killed. I don't know how to use this device, actually I want to try to port the YAFFS2 filesystem based on this emulated NAND, and it has been successfully ported in bare metal, I need some help.
In addition, there are some problems with this NAND driver:
1. Some debugging and logging must be enabled；
2. Compilation error under HOST_ARM64;
3. SPI NAND cannot be supported

And this is my .config
[config.txt](https://github.com/apache/nuttx/files/15290764/config.txt)
