u-boot + stratix EP1S40 + issue

Hi haq,

I'll take a look through your config, etc. In the mean time, a few questions:

-What Nios-II version are you using, Nios-II 5.0?

-What 1s40 sof are you using, the "standard" sof?

-Please post an objdump of u-boot (headers):

$ nios2-elf-strip u-boot

$ nios2-elf-objdump -h u-boot

Regards,

Hi scott,

Thanks alot.....I compiled the uclinux code based on marc leeman cross tool chain.....as well as instructions from his home page.........here is the link....

http://scorpius.homelinux.org/~marc/nios2.html (http://scorpius.homelinux.org/~marc/nios2.html)

I am using nios-II 5.0.

Also...I am using a file that comes with nios-II 5.0 ......under this

directory.(C:\altera\kits\nios2\examples\verilog\niosII_stratix_1s40\standard\std_1s40.ptf

in order to compile uclinux...here are the steps:

$ make ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc- hwselect SYSPTF=std_1s40.ptf

$ make ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc-

$ make ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc- menuconfig

the uclinux compiled...without any error & I used "nios2-download -g vmlinux" to download the kernel to stratix board...it's working fine...except that..I can do any thing.......untill I will able to communicate via u-boot.........then I will start on my research project.

thanks for the help.

Hi Scott,

Here is the output from U-boot after changing the config files.....and running under Win XP using hyperterminal.

once I ran "nios2-download -g u-boot".....I reboot my laptop in debian linux & then I opened a terminal with "kermit -c".program.....I got u-boot prompt....here is the output under debian linux.

Any idea......

BTW...I can't progam flash memory of my EP1s40 board using ur instruction......becuase I can't use nios2-console program ..it can't load the port driver...

error "''openport lpt1"...failed no driver loaded.

Any idea how to program flash ofr EP1S40 board.

Thanks,

Hi haq,

Just FYI, the latest u-boot sources were posted a few days ago and are available at:

http://www.psyent.com/download (http://www.psyent.com/download)

And patches were submitted to the main u-boot project at sourceforge.net -- but it usually takes

a few months for patches to show up.

BTW: it would be very helpful if you downloaded these sources and gave it a quick try

using the EP1S40_config.

> It's sitting for ever.......I don't know where I am doing wrong......

You might want to check all of your network settings and your tftp server configuration. Your

mac address in your environment is different than the one used by tftpboot. If you need a test

mac address, you can use the gen_eth_addr tool that comes with u-boot ... it will generate

a locally-administered mac for you.

> use nios2-console program ..it can't load the port driver...

tftpboot is the fastest way to download you images ... but that's not working for you at the

moment ... so you can use the loadb command with kermit to get your image into ram.

Just be careful not to download over the exception trampoline ;-)

Hi haq,

I see what's happening to your tftpboot now:

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

#define CFG_EXCEPTION_ADDR 0x01000020[/b]

--- Quote End ---

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

DK1S40 > tftpboot 0x01000000 uImage[/b]

--- Quote End ---

When you tftpboot to 0100_0000, you end up overwriting the exception trampoline.

Then, when the timer interrupt fires, you end up in the weeds. You should be ok if you use

a higher address:

DK1S40> tftpboot 1100000 uImage

Then you can:

DK1S40> imi 1100000

DK1S40> bootm 1100000

hi scott,

It didn&#39;t work properly......here are the steps after I download the u-boot on EP1S40 board using "nios2-download" under XP.

after I reboot & start my debian linux...with "kermit -c" ....I followed ur instuction.....& here what I got.

I am not sure if it&#39;s something to do with mkimage utility ........because....if I download the linux kernel alone....using "nios2-download -g vmlinux"....it display the booting process on hyperterminal.....Any idea.....what&#39;s wrong????

BTW, here is the command that I used to create uImage.

./tools/mkimage -A nios2 -O linux -T kernel -C gzip -a 0x01000000 -e 0x01000000 -n "Linux Kernel Image" -d linux.bin.gz uImage

Thanks,

Hi haq,

Where & when did you get your u-boot source tree? Did you download the u-boot

tarball from sourceforge, or did you checkout the sources from CVS? This was fixed

in the main source tree in April.

--Scott

Hi scott,

I am using u-boot-1.1.2 source from their wedsite.....I think I download it after april...anyhow..I saw today..they have a new release u-boot-1.1.3.

I will try to use that with ur config file........then I will post my results.....any other idea?

Thanks,

hi haq,

> I am using u-boot-1.1.2 source from their wedsite.....I think I download it after april

The reason I asked if you downloaded the tarball or directly from CVS is because the tarball

for 1.1.2 was produced prior to the changes being included in the source tree. So rather than

ask again, I&#39;ll just assume you&#39;re using the tarball.

> I will try to use that with ur config file........then I will post my results.....any other idea?

Yes, please get the u-boot sources from http://www.psyent.com/download (http://www.psyent.com/download), configure with

EP1S40_config, and run that image.

Otherwise, you&#39;ll be using old code ... last week there were five Nios-II patches submitted to

sourceforge, which may take several months to be incorporated into the source tree. The

sources at psyent already have these patches applied.
