uboot +uclinux + stratix EP1S40 board

[Altera_Forum]

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,

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.  > I am getting an error messages.....while using *.sof files that comes with nios-II IDE > kit.......while running "niso2-flash-programmer" utility program.  If you post the errors, someone might be able to help.  Regards, --Scott
