hi,hippo

i build the uclinux kernel as your guide.there is noting error occurred.

when i download the vmlinux(elf) to my board using command "nios2-download -g vmlinux",there are nothing output in my com port?

what is the matter? i cancel the jtag uart in menuconfig and do noting else.

my board is a custom board using cyclone ep1c6, the default board type in the menuconfig is stratix ,is this matter?

waiting for your replay.

thanks in advance.

you have to select nios serial in kernel config

            Nios serial support 
              Support for console on Nios UART  

PLEASE POST YOUR FUTURE QUESTIONS IN UCLINUX FORUM AS A NEW TOPIC.

Hi,

I have build hardware for Stratix GX development board without any error, but now I have problem with building uCLinux kernel. When I try to generate system.h

# generate nios2_system.h from ptf
make ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc- hwselect SYSPTF=stratixGX.ptf

it detects that I have 0 bytes ddr_sdram

--- Please select a device to execute kernel from:
(1) ddr_sdram
       Class: ddr_sdram_component
       Size: 0 bytes

SOPC builder system consists of nios2 cpu, ddr sdram controller (Base address 0x00000000, end address 0x07ffffff == 128MB ??), uart, jtag uart, timer, sysid, avalon tri state bridge and dummy cfi flash (not connected to any fpga pin). Can anybody help me?

Here is my ptf file:

dear hippo,

According to you,I download the builld.zip ,uClinux-dist-20051110,and nios2linux-1.4.zip,

then execute the ./build

this is the error information in the terminal :

can&#39;t find file to patch at input line 5

Perhaps you used the wrong -p or --strip option?

hi hippo

I meet a pb ,I used DEII board

i don&#39;t know how to change link address

view the rocessor type and features-->

can&#39;t find the (0x00500000) Link address offset for booting

plz help me

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/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
