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.
