need help on booting from cfi flash

[Altera_Forum]

hi hippo, 

 I am developing linux applications on CYCLONE_1C12_EVAL Board, following your instructions on website NiosWIKI.   I want to boot from CTI flash. But the linux didn't work but after programming. There is one point I am not clear. Please refer to the following scripts on NIOSWIKI, how do you get the address "0xC0000" in " sof2flash --offset=0xC00000 --". ------------------------------------------------------------------------------------------- cd arch/nios2nommu/boot# Creating .flash file for the FPGA configuration sof2flash --offset=0xC00000 --input=$SOPC_KIT_NIOS2/examples/verilog/niosII_cycloneII_2c35/standard/standard.sof --output=standard.flash# Programming flash with the FPGA configuration nios2-flash-programmer --base=0x00000000 standard.flash -----------------------------------------------------------------------------------------------    And Please help me to check whether the following selects are right or not.  (I) SOPC. I choose: reset from ext_flash  (II) The addresses in my nios2-system.h are chosen like these:  ext_flash: 0x0--0x800000 epcs: 0x800800---0x801000  (III) When "make vendor_hwselect SYSPTF=....", the items chosen are chosen ike the following:   --- Please select which CPU you wish to build the kernel against: (1) cpu - Class: altera_nios2 Type: s Version: 5.11 Selection: 1 --- Please select a device to upload the kernel to: (1) ext_flash Class: altera_avalon_cfi_flash Selection: 1 --- Please select a device to execute kernel from: (1) ext_ssram Class: altera_avalon_cy7c1380_ssram (2) epcs_controller Class: altera_avalon_epcs_flash_controller Size: 2048 bytes Selection: 1  I will appreciate much if you could spare a minute to reply.  Thank you,  Elec

hi hippo, 

 I found the problem myself. I should use EPCS to configure the FPGA.    ================================================   --- Quote Start ---  originally posted by electroman74@Mar 7 2007, 10:57 AM hi hippo,  i am developing linux applications on cyclone_1c12_eval board, following your instructions on website nioswiki.   i want to boot from cti flash. but the linux didn&#39;t work but after programming. there is one point i am not clear. please refer to the following scripts on nioswiki, how do you get the address "0xc0000" in " sof2flash --offset=0xc00000 --". ------------------------------------------------------------------------------------------- cd arch/nios2nommu/boot# creating .flash file for the fpga configuration sof2flash --offset=0xc00000 --    input=$sopc_kit_nios2/examples/verilog/niosii_cycloneii_2c35/standard/stand ard.sof --output=standard.flash # sof2flash --epcs  ......#  # programming flash with the fpga configuration nios2-flash-programmer --base=0x00000000 standard.flash #should use epcs: nios2-flash-programmer --epcs --base=0x800800 standard.flash -----------------------------------------------------------------------------------------------    and please help me to check whether the following selects are right or not.  (i) sopc. i choose: reset from ext_flash  (ii) the addresses in my nios2-system.h are chosen like these:  ext_flash: 0x0--0x800000 epcs: 0x800800---0x801000  (iii) when "make vendor_hwselect sysptf=....", the items chosen are chosen ike the following:   --- please select which cpu you wish to build the kernel against: (1) cpu - class: altera_nios2 type: s version: 5.11 selection: 1 --- please select a device to upload the kernel to: (1) ext_flash class: altera_avalon_cfi_flash selection: 1 --- please select a device to execute kernel from: (1) ext_ssram class: altera_avalon_cy7c1380_ssram (2) epcs_controller class: altera_avalon_epcs_flash_controller size: 2048 bytes selection: 1  i will appreciate much if you could spare a minute to reply.  thank you,  elec <div align='right'><{post_snapback}> (index.php?act=findpost&pid=22044)  --- quote end ---    --- Quote End ---
