[BUG] nsh and SmartFS file system are not SMP-proof
Description / Steps to reproduce the issue
-
On Pi Pico W board with Pi Pico SDK 2.0, setup a system with working flash SmartFS file system and without SMP, e.g., ./tools/configure.sh -l raspberrypi-pico-w:nsh-flash
-
verify that the following file creation, deletion and smart_test command work cd /flash echo Hello_NuttX > test2.txt cat test2.txt smart_test -w 2 /flash/test2.txt rm test2.txt
-
enable SMP and run ps or other command to verify that SMP is working ref: https://blog.mark-stevens.co.uk/2023/06/adding-smp-to-nuttx-on-the-raspberry-pi-picow/
-
try to re-run commands in step 2) notice that when executing file creation or deletion or smart_test command, nsh hangs. If there is a USB nsh and a telnet nsh, then both nsh hang.
Not sure if there is any other part of NuttX OS that is also not SMP-proof.

could you test on littlefs? so we can know whether is specific to smartfs.
Created a related bug: https://github.com/apache/nuttx/issues/13882 (Flash file system creation process does not take configured parameters on Pi Pico #13882), don't know how to create a working littlefs. Note that in menuconfig, selecting RP2040_FLASH_FILE_SYSTEM (Configure a read/write filesystem on unused flash memory) will automatically select SmartFS.
