Honored ContributorJrunner + Serial Flash Loader (SFL) + EPCS4 [How to programm EPCS without Quartus II]
Hello, I'd like to adapt Jrunner to work with Serial Flash Loader. I've integrated SFL megafunction into my design and it works great. When I click auto detect in quartus II programmer it detects ...

Honored Contributor --- Quote Start --- So you have built your own SFL rather than using the existing protocol? --- Quote End --- Yes, exactly. There is no documentation (not too much) about protocol used in SFL, so I couldn't be able to write a software for my DSP to use SFL. --- Quote Start --- But if I want to write a program (sof, rpd file, I still don't know which is appropriate) into EPCS, do I really need to use Virtual JTAG? JTAG is necessary for SFL, but not for altASMI_parallel megafunction? am I right? --- Quote End --- I program RBF into EPCS4 Flash. Virtual JTAG is for communicating with your design in FPGA. If you want to program EPCS using Altera software just stay with SFL. If you need to program it without using Altera software you need to 'hack' SFL protocol or create your own design (like mine). I don't see other exists.
