we are using micron parallel nor flash 256mb Rc256p33tfe with the cyclone iii device in active parallel mode
after adding generic tri state controller and conduit bridge in qsys
by giving frin command line : nios2-flash-programmer --base=0x01000000 --debug
its showing like below no cfi table found

by reading through c code by debugging
we got cfi information misssing at ox11 addresss it had to be 0x52 but its showing ox5100.
even though i tried to flash both sof and hex files from nois2flash prorammer gui
its showing
error code8: programming file path --verbose
i find cfi table information is missing i tried to override my cfi flash by nios2override file by placing it in path nis2eds/bin
its showing
cfi erase region definitions dont match with device size
base address not aligned in device size (in my qsys address of generic controller is 0x01000000 )
how can i access the flash because i have to load (hex or flash file ) through uart and i have to write in flash and run it on power on

eah its the same way i designed in the qsys and also while i writing to flash by following the datasheet procedure .
ox4089 if i am writing this 16 bit data in some 0x0 location
and while i am reading the location 0x0 its showing 0x89 and 0x1 location its showing 0x40.
its showing lsb in 0x0 location and MSb in 0x1 location.
through code its reading some cfi table locations according to datasheet.
so i think i correctley designed in qsys. and none of the above problems are solved .
and another question i converting .sof file to pof and i added cfi flash programmed through quartus programmer and it is stored in flash and application is running on power on. in same way if i convert the sof file to hex format and receive through uart and i will erase the flash and write the data in hex format manually through c code . will it run on power on condition
thaks for reply.
