Everyone who use the up3 board please help me to solve this problem.
I have saw "Errata_for_the_UP3_Users_using_Quartus_II_4.2" in sls website. The file points out<div class='quotetop'>QUOTE </div> --- Quote Start --- It will shows an error for the SDRAM Test component when any program is compiled for the generated system incorporating an SDRAM Controller sharing a tri-state interface. This bug has been removed in Quartus II v5.0 (SOPC Builder v5.0) and hence the in-built SDRAM Controller can be used with the tri-state interface in Quartus II v5.0 without any problem.[/b] --- Quote End --- But I compiled my design in Quartus_II_v5.0, it still had this error sometime. It worked well before I make my custom board for flash programer in up3. After this, it always show this error in my design. Of course, a few times it worked well also. How can I deal with this bug?? 3ks very much~Link Copied
