nios2-flash-programmer error code 1

Hi guys. I am new to FPGA world and seems like I am having some difficulties with the flash programmer that I cannot understand. Its giving me an error code 1 which I am unable to find a reference to.

Purpose of the implementation: test out different functionality of the DE2-115 board. The FPGA part of the program includes SW, KEY, LED, and lcd, all of which is connected to the nios system generated from Qsys

Qsys: includes clk, cpu, onchip memory, jtag uart, sysid, epcs flash controller and a bunch of PIOs.

Here is what I did:

1. set cpu reset vector to epcs.

2. export externals of epcs flash controllers. it gives me the following input/outputs: 


epcs_flash_controller_external_dclk  => CONNECTED_TO_epcs_flash_controller_external_dclk,  -- epcs_flash_controller_external.dclk            
epcs_flash_controller_external_sce   => CONNECTED_TO_epcs_flash_controller_external_sce,   --                               .sce
epcs_flash_controller_external_sdo   => CONNECTED_TO_epcs_flash_controller_external_sdo,   --                               .sdo
epcs_flash_controller_external_data0 => CONNECTED_TO_epcs_flash_controller_external_data0  --

3. apply terisic patch. as suggested in their manuals to include nios-2-flash-override 

# EPCS64N(lead-free)sector_size = 65536
sector_count = 128
# EPCS128N(lead-free)
sector_size = 262144
sector_count = 64

3. import some predefined pin assignments given by terasic.

4. On the Dual-purpose pins page (Assignments > Devices > Device and Pin Options), thefollowing pins are assigned to "Use as regular I/O": Data[0], Data[1], DCLK = Use as regular I/O, FLASH_nCE/nCS0

5. perform port map 

        u0 : component test_niosqsys        port map (
            clk_clk                            => CLOCK_50,                            --                         clk.clk
            lcd_external_RS                    => LCD_RS,                        --                lcd_external.RS
            lcd_external_RW                    => LCD_RW,                      --                            .RW
            lcd_external_data                  => LCD_DATA,                   --                            .data
            lcd_external_E                     => LCD_EN,                          --                            .E
            pio_key_external_connection_export => KEY,                 -- pio_key_external_connection.export
            pio_sw_external_connection_export  => SW,                   --  pio_sw_external_connection.export
            poi_led_external_connection_export => dataop,              -- poi_led_external_connection.export
            reset_reset_n                      => KEY(0),                            --                          reset.reset_n
            epcs_flash_controller_external_dclk  => DCLK,                -- epcs_flash_controller_external.dclk
            epcs_flash_controller_external_sce   => FLASH_nCE,    --                               .sce
            epcs_flash_controller_external_sdo   => DATA1,                 --                               .sdo
            epcs_flash_controller_external_data0 => DATA0  --                               .data0
                             --                       reset.reset_n
        );



Node                 Direction                        Fitter Location
Data0              Input                PIN_AA14
Data1              Output                PIN_V1
dclk                 Output                PIN_AG12
FLASH_nCE    Output                PIN_AD14

6. program the fpga.

7. open nios IDE, select BSP Editor from where all components of Settings->Advanced->hal->linker we disabled

8) built the program and select run as NIOS II hardware. At this point the program is correctly loaded and starts execution. however, upon pressing nios 2 reset key, the program stops since the epcs has not been flashed.

9. open up nios ii flash programmer from nios2 ide. confirmed timestamp and system id to be a match. add the sof and elf files with default settings. ... press start; and end up with an error saying 

elf2flash --input="/media/rash-ed-u/ubuntu/altera/workspace/nios_cpu/software/prog/prog.elf" --output="/media/rash-ed-u/ubuntu/altera/workspace/nios_cpu/flash/prog_epcs_flash_controller.flash" --epcs --after="/media/rash-ed-u/ubuntu/altera/workspace/nios_cpu/flash/nios_test2_epcs_flash_controller.flash" --verbose

Error: Error code: 1 for command: nios2-flash-programmer "/media/rash-ed-u/ubuntu/altera/workspace/nios_cpu/flash/nios_test2_epcs_flash_controller.flash" --base=0x81000 --epcs --sidp=0x82040 --id=0x0 --timestamp=1425416806 --device=1 --instance=0 '--cable=USB-Blaster on localhost ' --program --verbose

any idea what might be wrong with what i am doing?

Thanks

Cheers
