i'm having problems with a custom board. using quartus 4.2 and nios1.1 everything works fine. i decided to move to quartus 5.01 and nios ii 5.01 and the same projects that worked correctly with the old version failed with the new one:
using cable "usb-blaster [usb-1]", device 1, instance 0x00
pausing target processor: ok
reading system id at address 0x021208b8: verified
downloading 03000020 ( 0%)
downloading 03010000 (74%)
downloaded 86kb in 1.1s (78.1kb/s)
verifying 03000020 ( 0%)
verify failed
leaving target processor paused
almost always i get this error and i really don't know why. ther is sdram at 3000020, but i think the sdram is not the problem because with the old version everything worked fine.
have someone had the same problem before? please help!!

--- Quote End --- I have the same problem with you! And if has troubled me a long time,but I don't kown how to resolve it. somebody said that it was "the phase shit" about sdram and system,but when I set the sdram‘s phase earlier than the system's 27 rad,it didn't work either. I also wish someone can give us a help! Thanks!
