Honored ContributorWhat came out? Could you solve the problem?
I have a similar problem, since I use Quartus II 6.1, a Cyclone II FPGA and Nios II. With the SOPC builder I included an Epcs Serial Flash Controller and I want to use the Serial Flash Loader, too. When I add the serial flash loader Megafunction in the Quartus II project, what should I do with the nOE_IN pin??? In the document 'Using the Serial FlashLoader With the Quartus II Software' there is a good explanation on how to add the Megafunction to the project, but how to go on? The explanation is ---------------- Control signal to enable the SFL Megafunction. A low signal enables the Megafunction. SFL tri-states ASMI interface when it is disabled. ---------------- Can I put the the pin low the whole time? But 'The SFL image will be replaced with the new design' after finishing the configuration of the FPGA, right? Will it work then? To try something else I deleted this serial flash loader symbol from my project and used the serial flash loader as user_defined_interface in the SOPC builder. Generation in SOPC builder worked, Analysis and Synthesis in Quartus II was no problem, but after starting the fitter, the following error occurs: ---------------- Error: Can't place node "Graphik_sopcb:inst5|user_defined_interface_0:the_user_defined_interface_0|s erial_flash_loader:wrapper|altserial_flash_loader:altserial_flash_loader_componen t|data0out_int" of type ASMI block ---------------- Is the Serial Flash Loader already included with using the Epcs Serial Flash Controller? I would like to use the JTAG to program the EPCS configuration device in AS mode via the FPGA using the serial flash loader, but I can't find much information about that. Any help would be nice, thanks in advance!
