Hardware Configuration Setup:
Controller: STM32H7
Rtems : 4.11
External Memory: IS25LP016D (2MB flash or 16Mb 133MHZ)

For JFFS2 Configuration , I have followed the below link,

Please use the mailing lists for these kinds of problems. I suggest you remove the flash simulator code from the example.
