Hi,

could somebody tell me where to get my flash base adress http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/dry.gif

The fact is that when I looked in the standard design, I&#39;ve found that ext_flash is adressed at 0x00000000 and SDRAM at 0x01000000, but when I tryed to use the nios2-flash-programmer to upload the u-boot.flash (made with bin2flash) it&#39;s always failing with the 0x00000000 base adress, contrariwise, when I choose a 0x00800000 base adress, it works but the u-boot is apparently not in the user zone (I specified --location=0x00400000) since the green led of User il not lightened and u-boot not working.

I&#39;ve made that manipulation in the IDE, programmed flash in the user zone and it worked fine.
