uboot +uclinux + stratix EP1S40 board

Hi everyone,

I been trying to port uboot for stratix EP1S40 board for the last 2 months...but seems like I have no luck...I already posted my issues couple of times.....but no luck so far.

I have a very simple task...all I want is to load uclinux from SDRAM address 0x01000000 with uboot ........so that ....the board runs uclinux when power is applied........without running "nios2-download -g vmlinux" everytime.

The vmlinux is created using std_1s40.ptf file that comes with nios-II development kit IDE.

I downlaod the source code of u-boot-1.1.2........and just use the pk1c20 board files as reference............. to create u-boot.bin for stratix professional edition board EP1S40.

I couldn't see any major difference between these 2 boards. I am not a hardware person ............... just try to follow the logic.

Anyhow......I am now stuck here with u-boot.bin, u-boot and u-boot.srec....files...don't know how to download the u-boot to stratix EP1S40 board using altera's utility programs that comes with nios-II IDE kit.

I am getting an error messages.....while using *.sof files that comes with nios-II IDE kit.......while running "niso2-flash-programmer" utility program.

I am not sure if I am following the right path.......while using the pk1c20 base code.

Is anyone can guide........how to program flash memory using nios-II SDK utilities.

thanks,

    Hi haq,

    What exactly is the problem you are having with u-boot?

    And each time you have received a reply :-) But you never provided any feedback.

    If all you want is to run uclinux when power is applied, you don't need u-boot.

    1. start your terminal software.

    If your using the jtag uart, run nios2-terminal. Otherwise, startup your terminal emulation

    software (e.g. Hyperterminal).

    2. make sure u-boot is working.

    Run:

    $ nios2-download -g u-boot

    If you don't get the u-boot command prompt, then you didn't port u-boot correctly.

    If you post the errors, someone might be able to help.
