How do I get this chipdb file: xc7a35t.bin? #67

Closed JamesTimothyMeech closed 1 year ago

I have followed the install instructions but I can't see any of the files that should populate /xilinx-chipdb/xc7a35t.bin. Which part of the install do I need to revisit to get these files?

Is there any command I can run to generate or download these files?

You have to generate the database file and then create the .bin following the directions from "Building the Arty Example". Get the database file by git submodule init and git submodule update. then do: pypy3 xilinx/python/bbaexport.py --device xc7a35tcsg324-1 --bba xilinx/xc7a35t.bba ./bba/bbasm --l xilinx/xc7a35t.bba xilinx/xc7a35t.bin
