Unfortunately, this version of Symbiflow has only been tested on Ubuntu 20_04. I am glad that you have found a fix for your Linux distribution.

The reference manual has a section of the FPGA. If you want to understand how to interface the FPGA I would suggest the following additional resources https://github.com/coolbreeze413/qorc-onion-apps This has a range of basic examples of how to interface the EOS device with your FPGA design. A video...

Please find the answers to some of your questions. I understand from forum posts here that the QFN packaging is effectively end-of-life and that, as of last year, Quicklogic had been looking for a similarly user-friendly replacement package. Has Quicklogic made any headway in identifying one? Rob>> ...

The QuickLogic support for EOS S3 has been rolled into the f4PGA release at https://github.com/chipsalliance/f4pga-examples Instructions on installing and running the demo is available at https://f4pga-examples.readthedocs.io/en/latest/getting.html Example project is available at https://github.com/...

The only difference between the two boards is that the Lite version doesn't have the Pressure sensor - Infineon DPS310 populated. So there is no new schematics

QuickLogic was the first FPGA company to add DSP into the FPGA with the EclipsePlus family. Unfortunately, these DSP’s are only 8-bits and they need to use FPGA routing to cascade together. I don’t believe that it would be very efficient to implement 32x32. Another alternative is the EOS S3, which h...

Question I can see that there is a ADC module, but it is not clear how to configure the 2 ADC channels and connected to the external world. QL Answer>> EOS S3 has two channel of ADC, on the QuickFeather and BGA package, and 1 channel on the WLCSP package It is a 12-bit ∑Δ Analog-to-Digital Converter...
