we can mount a zipfile in nuttx use mount command like this: mount -t zipfs -o /data/test.zip /zip The zipfs is a read only file system,The advantage is that it does not occupy additional space when reading the decompressed file. When used, reading and decompression operations are simultaneous. The known disadvantage is that when using seek to read forward, it will reopen and cause slow speed problems.
