hi, please reply . i am using micromn p33 65nm parallel nor flash cfi compliant(part num RC28F256p33TFE) . In qsys i added tristate controller and tri state conduit bridge . in program By giving cfi read command through (IOWRand IORD) and reading particular addresees 0x10 ,0x11,0x12 its giving ox10 -51(Q),(0x11-0x5100),(0x12-0x59). for 10 and 12 addresses it is showing correct query but for ox11 it showing wrong instead of 52 it is showing again 51. and also in nios 2 flashprogrammer it is showing no cfi table at address. i dont understand whats going wrong .please help me . please reply for my query

also when programming the current flash file from nios2flash programmer GUI its showing error code 8

also from command line i tried both the flash file and override file . it shows error both like unable to open the file what could be the exact reason . anybody please look into this issue

Can you check and refer to the attached.

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.

  yeah that's working fine .
  
  but i dont want that ,i converted sof file to .flash file and write it in ox20000 onwards by receiving the data in .flash file through uart but it is not booting on power on .
  
  do we need to write other than converted sof file to boot up on power on .
  
  do i need to convert pof file to hex file and write that data from 0x20000 onwards but pof file is having other data than .sof file do we need convert pof file and write to flash i want to know that data .
  
  or any other suggestions . actually in all pdfs its mentioned we have to write from 0x20000 onwards
