Could you provide instructions and an small example?
Hi. I know that it is experimental, but I saw a blinking led several months ago on Twitter (I didn't find it again). I have a DE10-nano and I want to try (as far I remember, the example was in this same board).

So, first, you need Yosys. Build it with make -jN
, install it with sudo make install
. You should now have a command called yosys
.
Next, download Mistral, and set MISTRAL_ROOT
as the path to it. While you can build the source to get the mistral-cv
command, normally Mistral and nextpnr are built together.
Next, download nextpnr, make a build directory inside the nextpnr source and enter it, build it with cmake .. -DARCH=mistral -DMISTRAL_ROOT=$MISTRAL_ROOT && make -jN
, install it with sudo make install
. If the build fails due to running out of memory, just retry it. You should now have a command called nextpnr-mistral
.
Next, download openFPGALoader, make a build directory within the source directory, enter it, run cmake .. && make -jN
, and install it with sudo make install
. You should now have the command openFPGALoader
.
Finally, download mistral-test, enter the tests directory, edit the Makefile to remove the --compress-rbf
option from nextpnr (compressed bitstreams cannot be loaded through JTAG), run make blinky.rbf
to build the bitstream, and then openFPGALoader -b de10nano blinky.rbf
.
Great! Thanks. I will try and let you know.
