Occasional Contributorcan anyone tell me how i can know the external flash is connected .
i added generic tristate controller and conduit bridge in qysys.
and assigned pins in pin planner .
i want to write to nor flash but target is not connection
it is shwing "no nois 2 target is conncted or sof is not downloadded.but i did both 2 of them and i refreshed so many times.
can anyone tell me what i am doing wrong
Frequent Contributordid you mean you can't write to the CFI flash? any log?
Occasional Contributorwe 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

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 from memory.
Frequent ContributorCan you check and refer to the attached.
Occasional ContributorHello
Can we access or flashing Directly from FPGA if we doesn't have CPLD in our Board?
Occasional ContributorNo,we didnt have cpld in our board ,we normally flashing through jtag in quartus prorammer by convertiong sof to pof . it is running fine after power on . but in final level after system integration it's not possible to flash using jatg .
so we have to download it through uart by writing the file flash manually from 0x20000 .
Is it workout .
and also problem with generic tristate conroller behaving like explained below
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 .
please answer these two questions.
Occasional Contributoryeah we can access the flash through fpga without cpld in quartus programmer and also with nios ii flash programmer .after
compilation stage goto
programmer section and attach or add your fpga device and browse for .sof file if u want to program to flash
right click on fpga device and u can find attach flash option .
u can choose which flash u used in your card .
and programm it.
Occasional ContributorHello
I am trying to configure EP2AGX Arria® II GX using EPM240 Max ii CPLD and on board having CFI Flash js28f256m29ewh
In my case our custom Board having Flash Address bus A0 to A24 bus and Data D0..D7 Bus connected with FPGA CEn, OEn, WEn with FPGA
In case of cpld we have only Flash Address bus ,CEn and OEn, pins WEn not connected with CPLD and also there is no data bus between cpld an flash
So That's why I am confuse how to program flash memory
Is it with from CPLD Or FPGA because of Flash Data Bus only connected with FPGA configure data 8 bit port like DATA0 to DATA7
That s why I asked you
In your Above case I think its Big Endian and Little endian Issue I did this issued in PIc32 MPU
Thanks for your Reply knowledgeable

Occasional Contributorhi nome ,
In ur board there is no flash data bus lines connected to ur P2AGX Arria® II GX or EPM240 Max ii CPLD.
CFI Flash js28f256m29ewh for this flash if there is no data lines u cannot use it .
its like waste piece in board.
Occasional ContributorHello praveenkumar
As above I told Data Bus only connected with FPGA EP2AGX Arria® II GX
No Data Bus connected with CPLD even no WEn pin connected with CPLD
So That's why I am confuse how to program flash memory by CPLD OR FPGA
Thanks
Nome
Occasional ContributorHello
Thanks for your reply
True But Flash address bus A0 to A24 is connected With CPLD CEn and OEn, pins and also
One 12 bit Data Bus connected between CPLD and FPGA
My question is If we want to use Cpld as a flash programming first Load SOF in Fpga to connected Flash Data Bus to CPLD data Bus also WEn pins
Maybe CPLD will work as a flash Programing
What would you say ?
Thanks
Nome
Occasional Contributorhi ,
good to hear that but u r flash is 12 bit data bus or other .
and also have u ever tried to access the flash with nios ii software or some other programming .
in my project there is an issue which i mentioned above .
try to reply to my email :
praveentatikonda2155@gmail.com
Frequent ContributorHave you tried to program your flash using Quartus Programmer and PFL.
You can refer to below for PFL IP:
https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug_pfl.pdf
Occasional Contributoryeah i tried with pfl ,
actually i initilized onchip memory with hex file and i genreted the sof file .
and that sof file is converted into pof file .
that is wroking fine on power on .it s stored in the flash .
but when i add tristate controller and conduit bridge its not working .i tried all the methods explained in edhandbook.
when i add sof and hex file separately to generate the pof and i programmed its not working.
i want to know the pof file content and when converted to .hexout there is so much data .i want to know the addresss in which that data of pof is storing in cfi flash locations.
