LittleFS for RT1176

[lfost]

Looking for information on running LittleFS on an RT1176.  I want to run LittleFS out of qspi flash and also write files to the same qspi flash.  The standard nxp LittleFS code runs out of ram which will not work in our application.  What are the pros and cons of attempting to do this.

Hi @lfost ，
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
-- What are the pros and cons of attempting to do this?
-- It's easy to access the flash memory if the code run into the RAM, further, the whole space of flash memory is able to be accessible, however, when executing the code in the QSPI, the FlexSPI driver needs to be relocated into RAM, further, it shouldn't program or erase the sectors that be occupied by the code, otherwise, it causes code crash issue.
Anyway, the developer is able to modify the demo evkmimxrt1170_littlefs_shell_cm7 to enable running in the QSPI.
Have a great day,
TIC

Do you have any sample code that LittleFS runs out of qspi and writes back to the same qspi.  Do you have a linker script that does the sectioning of the flash.

Thanks.  I will checkout the sample code.
