curuvar opened a new pull request, #6998:
URL: https://github.com/apache/incubator-nuttx/pull/6998

   ## Summary
    
   This code implements a Sector Mapped Allocation for Really Tiny (SMART) 
filesystem in the RP2040 flash memory chip.  It uses the space not otherwise 
used by the NuttX binary and supports both read and write access.  The initial 
state if the filesystem can be set when a new program is uploaded to the 
RP2040.  Data subsequently written to the filesystem persists across re-boots.
   
   ## Impact
   
   This bulk of this request is RP2040 only, although a few common SMART 
filesystem source files were updated to correctly handle unaligned access.
   
   ## Testing
   
   This change has been tested on a RaspberryPi pico W. Data has been read and 
written by various NSH commands and the tests in smart_test work as expected.
