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.. am using the latest build 11.1 sp1 Web edition.
Any updates on this error/issue ?? Kindly help in case if you are familiarI 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 - lb_n be_n - 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.
