Hi all,
I meet a new problem when programming flash in NiosII IDE. Just because the err popped during regeneration, I removed the epcs_controller from the components list of my design in the SOPCBuilder.Then I regenerated the actual design,it proved successful.After this, I updated the symbol in the .bdf and recompiled.After the compilation,I builded a new project "hello_led" from the template projects list in the NiosII IDE. It seemed that building and later running as NiosII Hardware either was OK. However,when I tried to program this project into the flash on the dev board,some err message came out, -----------------------# ! /bin/sh# # This file was automatically generated by the Nios II IDE Flash Programmer.# # It will be overwritten when the flash programmer options change.# cd E:/EDA/UP3/design/The_Last_One/software/hello_led_1/Debug # Creating .flash file for the FPGA configuration $SOPC_KIT_NIOS2/bin/sof2flash --flash=U8 --offset=0x700000 --input=E:/EDA/UP3/de sign/The_Last_One/For_UP3.sof --output=For_UP3.flash Info: ******************************************************************* Info: Running Quartus II Convert_programming_file Info: Command: quartus_cpf --no_banner --convert E:/EDA/UP3/design/The_Last_One/ For_UP3.sof For_UP3.rbf Info: Quartus II Convert_programming_file was successful. 0 errors, 0 warnings Info: Processing ended: Wed Jul 27 18:11:52 2005 Info: Elapsed time: 00:00:01 WARNING: Default charset GBK not supported, using ISO-8859-1 instead # Programming flash with the FPGA configuration $SOPC_KIT_NIOS2/bin/nios2-flash-programmer --input=For_UP3.flash --sof=E:/EDA/UP 3/design/The_Last_One/my_new_board/system/my_new_board.sof --base=0x00200000 Jul 27, 2005 6:11:53 PM - (??) nios2-flash-programmer: Launching Quartus Program mer to download: E:/EDA/UP3/design/The_Last_One/my_new_board/system/my_new_board.sof Unable to synchronize with target.

But I cannot figure out why,because I successflly made my target board and builded the "hello_led" project.So I wonder whether this problem might be has somthing with my removing of the epcs_controller. Could you please give some suggestions about that? Thank you in advance! Regards, Don ps.I use the mux module provided by SLS to the NiosII module running on the board.So I only make a LCD_RW _N signal as hign level to disable its sharing of the tri-state bus.(Because the SRAM shares the same Read signal as the flash on the board,and the SDRAM has not a read signal. )Link Copied

After these days' work,I still cannot resolve this problem, http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif
could anyone give me some suggestions? Many thanks to you!- Mark as New

Hi Don,
Is For_UP3.sof your flash programming design, or your normal system design? --Scott- Mark as New

Thanks Scott!
That's right,For_UP3 is the top entity of my design,and the .sof file is For_UP3.sof,could you give me some suggestions please?- Mark as New

I wonder is there something with the EPCS controller?

Hi Don,
I don't have a UP3 board ... but as I recall, it only has 2MB of flash. Soooo ... <div class='quotetop'>QUOTE </div> --- Quote Start --- $SOPC_KIT_NIOS2/bin/sof2flash --flash=U8 --offset=0x700000 --input=E:/EDA/UP3/de sign/The_Last_One/For_UP3.sof --output=For_UP3.flash[/b] --- Quote End --- <div class='quotetop'>QUOTE </div> --- Quote Start --- $SOPC_KIT_NIOS2/bin/nios2-flash-programmer --input=For_UP3.flash --sof=E:/EDA/UP 3/design/The_Last_One/my_new_board/system/my_new_board.sof --base=0x00200000[/b] --- Quote End --- doesn't appear correct -- specifically the offset. Did you use mk_target_board to create the flash programmer design my_new_board.sof? Regards, --Scott- Mark as New

Now I could see the flash programmer in the NiosII IDE
indeed work,because I see something like this while programming: -------------------------------------------------------------------- Pre-Reading 85KBytes of data from U15: |----.----+----.----| ********************* (31.454 sec). Aug 2, 2005 6:51:09 PM - (??) nios2-flash-programmer: Success. Zero bytes writt en to U15- (because device matched contents of For_UP3.flash) Aug 2, 2005 6:51:09 PM - (??) nios2-flash-programmer: Flash programming complete --------------------------------------------------------------------- However,there comes out some new message after above like this:: ----------------------------------- Aug 2, 2005 6:51:10 PM - (??) nios2-flash-programmer: Input file empty--no data to program into flash. Exiting. Aug 2, 2005 6:51:11 PM - (??) nios2-flash-programmer : SOF-download skipped. Aug 2, 2005 6:51:14 PM - (??) nios2-flash-programmer : Flash file is too large to fit in flash memory ----------------------------------- But at then what the design I wanted to program into the Flash is a "Hello_World" project template,perhaps the smallest design of all. So how could this file be so large that cannot be programmed into the Flash chip,whose size is 2M ? Besides,I tried to program some other template projects into the Flash chip,but the message were all the same as above indicating they were too large to program. Could anyone tell me why this happen? Thanks in advance! Regards, Don- Mark as New

Hi Don,
> So how could this file be so large that cannot be > programmed into the Flash chip,whose size is 2M ? > Could anyone tell me why this happen? Because _now_ you're writing into U15, which is an EPCS1 device which has a 128 KB capacity (split between the configuration data and your app) -- not U8 which is the parallel flash device (2 MB). Don, if want to find a solution, you shouldn't keep changing the problem ;-) Good Luck, --Scott- Mark as New

Thanks Scott!
Sorry, I really didnot mean to keep changing my problem . http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/wink.gif I got the solution of the first post from Altera's mysupport, and then I made a new target board aimed at programming the epcs_controller.But as you see,the new problem I met is due to the limited size of the EPCS chip. http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif From your suggestions, I 'm gonna make another target board aimed at programming the flash instead of the epcs_controller, and I think I should set the reset address of the system to Flash(0x0000), do you think would that work? Many thanks:) Best Regards, Don
