Hi @mwilkinsonjr Yes, you have the clear chip from

2304

, let me know exactly the which repo versions do you want and I'll get it for you, the md file is outdated. And yes, you should be using the

/util/ftdi_flash.py

script to flash, thank you for bringing it to my attention that it is not in the readme file, I will add it.

Cool and thanks... Yeah I've been making educated guesses on what tags/commits/releases of the various repos was used here... Tiny Tapeout 3 was also on 2304 so at the moment I'm currently using the same commits/releases (for OpenLane, PDK, etc) as that did at tapeout. FYI it appears that maybe commit e7406bc of vtr referenced in the SOFA branch of efabless/OpenFPGA_bitstream_generation was squashed so I've been using commit 90ee686 from the master branch instead... but if there is a better remote ref do feel free to let me know 🙂

You should be using a branch called

SOFA

in our fork, steps can be found here https://github.com/efabless/clear?tab=readme-ov-file#steps-for-using-openfpga-to-generate-bitstream-for-sofa-fpga-fabric
