Is a SPI over JTAG bitstream possible with Gowin parts?

Open jevinskie opened this issue 3 years ago • 1 comments

After reading the comment and the doc about bitbanged SPI programming I was wondering if loading a bitstream to then do faster SPI over JTAG is feasible. If so, it’s something I’d like to contribute.

Using a bitstream to do the bridge is faster yes. But, as far I know, litlebee doesn't have user jtag interface. So this approach is impossible :-/
