BSP Generation Error

I am using NIOS for LCD and Key pad Control, recenlty am trying to interface SRAM for the nios code and have built a QSYS system for the same. when am trying to Re-generate the BSP in NIOS II i am getting the following error,

Problem Occured:

"Generate BSP.. keyp_disp_sram_sys_bsp" has encountered a problem

Error executing ' nios2-bsp-generate-files --bsp-dir--settings settings.bsp, unexpected return code 1

Error Message:

SEVERE: BSP not valid

SEVERE: BSP not valid

SEVERE: nios2-bsp-generate-files failed

Please do help me out how i can get out of this..

    Any updates on this error/issue ?? Kindly help in case if you are familiar

    I am not sure regarding the interface of nios-sram output and actual pins of the sram

    i get the following from nios-sram

    address[15..0]

    be_n[1..0]

    data[15..0]

    read_n

    write_n

    select_n

    i am connecting them to the following on sram (CY7C09289)

    address[15..0] - address[15..0]

    be_n[0] - lb_n

    be_n[1] - ub_n

    data[15..0] - data[15..0]

    read_n - oe_n

    write_n - r/w_n

    select_n - ce0_n

    NOT(select_n) - ce1

    i am not sure how to connect the CNTEN_N, CNTRST_N, ADS_N signals !!

    based on the datasheet i am connecting them as (Address load to address register)

    CNTEN_N - XX (Dont care)

    CNTRST_N - HIGH

    ADS_N - LOW

    I compile the quartus and flash the quartus code in JTAG, its fine

    When i try to run NIOS HARDWARE, I am still getting the error i have mentioned earlier -

    "Downloading ELF process failed" - the address location points to the SRAM !

    Please help at the earliest !!!! Thanks in advance

    I have attached the Cypress SRAM datasheet - i am using one port of the SRAM only

    Perhaps the directory is read only. This line doesn't really make sense since the bsp-dir argument isn't set to something valid:

    Error executing ' nios2-bsp-generate-files --bsp-dir--settings settings.bsp, unexpected return code 1

    Have you tried using the command line instead? If you want to see an example go through the Qsys tutorial, there is a script there that builds the BSP and application.
