21 years agoDoes anyone here has you UP3 wrok well?
My development board is UP3 from sls corp.
If I just use the sdram or the sram or the flash, it works very well without any problem. But if i use them together, that means, a tri_state_bridge is necessary, and I must add a mux to organize the I/O signal, ps: these memory decevices use shared pins. Then the problem comes, i can't run any programme on the board any more. Does anyone come cross the same problem? And there is another question: the sdram pins is shared by other device, but the sdram controller use slave port but tri_state slave port, even if you set the controller with "shared dqm/dq/ I/o pins", can it works well? Thank you!4 Replies

Which version did you download?
I have downloaded the "Accessing Memory" design for quartus 4.1 and if I don't modify it but directly download it to the fpga, it will work well. But if I modify a little, everything will changed:( PS: I am using Quartus 4.2. Then I downloaded the "Accessing Memory" design for quartus 5.0 , and it still doesn't work anyway. Do you just use the reference design or construct the system by yourself using the sls component( lcd & sram)? And what your quartus version is? Thank you so much!! - Altera_Forum

Today I build the whole system by myself without the refrence design, and everything seems ok.
So now I doubt there must be something wrong with the refrence design from sls corp http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif Thank you all the same!
