Hi. 

Problems wits Nios Flash Programmer, board with nios on Cyclon II.  I have desined board with Cyclon II , sof-file generate without errors, software designed in IDE NIOS, elf-file compailed.  I configurate my sof-file by JTAG Quartus Programmer, operation complet OK. Debugger successfully run program , trace also work.  But i have problem - Nios Flasf Programmer can not programming Epcs flash.  I have log: -------------------------------------------------------------------------------------------------------------------------# ! /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 C:/altera/qdesigns60/controlmodule/WORKMODULE2/software/workmod2_ver1/Release # Creating .flash file for the FPGA configuration $SOPC_KIT_NIOS2/bin/sof2flash --epcs --input=C:/altera/qdesigns60/controlmodule/ WORKMODULE2/workmodule2.sof --output=workmodule2.flash Info: ******************************************************************* Info: Running Quartus II Convert_programming_file Info: Command: quartus_cpf --no_banner --convert --device=EPCS64 --option=workmo dule2.opt C:/altera/qdesigns60/controlmodule/WORKMODULE2/workmodule2.sof workmod ule2.pof Info: Quartus II Convert_programming_file was successful. 0 errors, 0 warnings  Info: Processing ended: Fri Mar 18 15:39:54 2011  Info: Elapsed time: 00:00:02 Info: ******************************************************************* Info: Running Quartus II Convert_programming_file Info: Command: quartus_cpf --no_banner --convert workmodule2.pof workmodule2.rpd Info: Quartus II Convert_programming_file was successful. 0 errors, 0 warnings  Info: Processing ended: Fri Mar 18 15:39:56 2011  Info: Elapsed time: 00:00:02 # Programming flash with the FPGA configuration $SOPC_KIT_NIOS2/bin/nios2-flash-programmer --cable='USB-Blaster [USB-0]' --devic e=1 --sidp=0x00000610 --id=1944443831 --timestamp=1300448607 --epcs --base=0x000 00800 workmodule2.flash Using cable "USB-Blaster [USB-0]", device 1, instance 0x00 Resetting and pausing target processor: OK Reading System ID at address 0x00000610: verified   : Checksumming existing contents   00000000 : Verifying existing contents   00010000 : Verifying existing contents   00020000 : Verifying existing contents   00000000 : Reading existing contents   00010000 : Reading existing contents   00020000 : Reading existing contents   Checksummed/read 192kB in 10.6s   00000000 ( 0%): Erasing   00010000 (33%): Erasing   00020000 (66%): Erasing   Erased 192kB in 0.0s   00000000 ( 0%): Programming   Program failed  Leaving target processor paused # Creating .flash file for the project $SOPC_KIT_NIOS2/bin/elf2flash --epcs --after=workmodule2.flash --input=workmod2_ ver1.elf --output=epcs_controller.flash --boot=$SOPC_KIT_NIOS2/components/altera _nios2/boot_loader_epcs.srec # Programming flash with the project $SOPC_KIT_NIOS2/bin/nios2-flash-programmer --cable='USB-Blaster [USB-0]' --devic e=1 --sidp=0x00000610 --id=1944443831 --timestamp=1300448607 --epcs --base=0x000 00800 epcs_controller.flash Using cable "USB-Blaster [USB-0]", device 1, instance 0x00 Resetting and pausing target processor: OK Reading System ID at address 0x00000610: verified   : Checksumming existing contents   00020000 : Verifying existing contents   00020000 : Reading existing contents   Checksummed/read 64kB in 1.9s   00020000 ( 0%): Erasing   Erased 64kB in 0.1s   00020000 ( 0%): Programming   Program failed  Leaving target processor paused  ---------------------------------------------------------------------------------------------------  I tried in my software write to epcs, using: alt_write_flash(fd, 0, ibuf_epcs, 256), and read , using alt_read_flash(fd, 0, obuf_epcs, 256).  Data block was writen successfully and remained in flash after power Off/On.  Next running nios flash programmer only erase Epcs. Sometime flash programmer can finish programming, but data really not stored in Epcs, only erasing is completed.  I need Help. Have somebody any ideas?

Problem is solved by connecting on line TCK of JTAG capacitor of 10pF to GND.
