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.
