README
README.mdexperimental sound processing board with XC6SLX9-TQG144 and TLV320AIC3204
Work is in progress.
Currently board is capable of receiving and sending the audio samples with a codec and passes the loopback test from FPGA pins.
FPGA bitstream config is stored inside the STM32F401RE internal flash.
Quick and dirty firmware loader is here: https://github.com/electrodyssey/lboard2flashboot
Working full-duplex aic3204 configuration script is saved in aic3204script directory:
codec receives: MCLK = 11.2896 MHz,
and generates: BLCK = 2.8224 MHz,
WCLK = 44.1 kHz
Please check the CHANGELOG for the updates

Questions
How big is the Lboard2 PCB?
It measures 203.2 × 101.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Lboard2 use?
230 parts, built around the M25P16-VME6, FT232RL, L5973D and AMS1117-1.8. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Lboard2 KiCad files?
From the electrodyssey/lboard2 repository on GitHub, at the commit this page was made from: the board is lboard2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Lboard2 design in my own project?
Its repository publishes it under the LGPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
