.... Ok so after tying MSEL[1] to VCCA, the AS problem is solved.

My second issue is the FLASH PROGRAMMER which comes with the NIOS II Software Build Tools. I am able to now use JTAG mode and AS mode with Quartus II. I usually use the Flash programmer to do a complete programming(Quartus and NIOS code).

I do the following,

  1. JTAG the FPGA board, write the sof. NIOS II CPU reset vector pointing to EPCS device.

  2. Note that in NIOS the all Linker segments apart from entry and exceptions point to sram_0 (2Mb SRAM)

  3. open NIOS, generate BSP, build project and the open the flash programmer.

  4. Add Choose the BSP/SOPC file.

  5. add .sof file

  6. add .elf file

  7. add offset for elf file based on sof file size

  8. and run the programmer.

i am getting the following error.

Error: Error code: 8 for command: $SOPC_KIT_NIOS2/bin/nios2-flash-programmer "G:/qcon/qcon_fpga_card/quartus/qcon_v0/flash/qcon_v0_epcs_flash_controller_0.flash" --base=0x83800 --epcs --sidp=0x84188 --id=0x0 --timestamp=1347252982 --device=1 --instance=0 '--cable=USB-Blaster on localhost [USB-0]' --program --verbose

Kindly help. note: am able to run the nios code from sram using jtag and "run as nios ii hardware" menu.
