-### Notes on Flash Layout of non PSA tagets with external storage
+### Notes on Flash Layout of non PSA tagets with internal flash
 
 - This is the default implementation at the default mbed_app.json
 - The default flash layout is tested with GCC_ARM compiler with newlib-nano and release profile only. If a different compiler is used, the bootloader binary size will be larger and the offsets needs to be adjusted.
-- The KVSTORE regions require even number of flash erase sectors.
