Hi Stephan,
It works now...in fact, my reference design for STRATIX configuration was not similar to the IO mapping used by u-boot for NIOS... It works with the Altera's "standard 32" reference design (with the .SREC in the CDKNIOS project and after u-boot recompilation too). I'll write a little doc on the IO and memory mapping to respect in order to used u-boot... My student will work on the u-boot APEX port...just an adaptation I think... I may be a good idea that the stratix 1S10 board appears as its own board and not as a cyclone board in the u-boot distro... My next step is to see is the standard 32 reference design is OK for uClinux support in order to freeze the hardware.... Many thanks; Pat

Hi Stephan and Scott; I've just quick and dirty downloaded the .srec contained in the RPM package from the Stephan's CDK4NIOS project...and seen what it happens...
Note: Stephan == Stephan (maintainer of CDK4NIOS :-)
Further, I think the included .srec contained in the RPM are untested !!! You should rebuild from sources (already patched and installed under /opt/cdk4nios/src/u-boot-$version).
no traces on my screen...
Hm, Do you have upload u-boot.bin to address 0x40000 (I think it's default for nios-run -r u-boot.srec) ?
Do you have upload the standard32 NIOS CPU image to user area (flash 0x600000) and start it by press SW10 (Reset. Config) ?
I've printed all the doc on u-boot and work on them during the week end. I have Altera's APEX board. One of my student 'll work on the u-boot port for this board...u-boot will be available for each Altera's board :-)
Great, the APEX port stands on my todo list. Nice to read this .. In the next few weeks I will get a old APEX board. The port should coming fast, because the NIOS standard32 CPU is nearly equal to Stratix/Cyclone.
If Scott has ported uClinux to NIOS, I'm very interested by this port...at this time, it only exists a commercial port form Microtronix...and I prefer having a GPL solution...
Cheers, Pat.

hi all, I'm trying to use u-boot on a altera's stratix 1S10 board.... I've downloaded the stephan's RPM u-boot port for this board...and downloaded intoo my board...but it doesn't work has anyone succeded to boot u-boot on this board?
Yes, I did. It works good to me.
is the port incorporated in the 1.0.0 u-boot version...I just see the cyclone board....
Sorry there was no time and no very important reason to release the Stratix pacht to u-boot cvs (I think, I can do it now :-), because there are no significant differences between Cyclone and Stratix in context of current U-Boot code. Further this patch depends on a few outstanding patches, one for a DK1C20 configuration bug fix and the other one for the LAN91C111 ethernet driver (see: http://sourceforge.net/mailarchive/forum.php?thread_id=3410088&forum_id=... 898).
Here the patches you need against current 1.0.0:
1.) LAN91C111 ethernet driver
Patch: u-boot-smc91111_fix.patch.bz2 State: waiting of a successful validation and cross verification from Richard
- bug fix: change type of smc_mac_addr[] from signed to unsigned
(important) - bug fix: LED configuration (defines in header)
- bug fix: write to right PHY register (PHY_MASK_REG)
- exclude version string for non-debug versions (saves memory)
2.) DK1C20 configuration bug fix
Patch: u-boot-dk1c20_cfg_fix.patch.bz2 State: waiting of CVS inclusion by Wolfgang
see: http://sourceforge.net/mailarchive/forum.php?thread_id=3397431&forum_id=... 898
Wolfgang, could you put it into the CVS repository?
3.) DK1S20 Stratix support
Patch: u-boot-dk1s10_support.patch.bz2 State: not released at u-boot list -- I'm not sure about (if finished or not)
For Stratix I've copied include/configs/DK1C20.h to include/configs/DK1S10.h, change CONFIG_DK1C20 to CONFIG_DK1S10, and expanded main Makefile to new board configuration DK1S10_config. For this new board configuration Cyclon's board directory board/dk1c20 will be used too. In it I've expand checkboard() with a second board-ID string.
You can download all the patches from CDK4NIOS project file list at sourceforge.net:
http://sourceforge.net/project/showfiles.php?group_id=81497 (go to the end, looking for resources --> patches)
Is anyone try to port µClinux on NIOS ? I'm currently working on this
Hm, I think Scott McNutt works with uClinux on NIOS. Ask him, he is the maintainer of NIOS U-Boot port.
point and having a linux bootloader is the first step...
Yes, and U-Boot works already.
Best Regards
