This document is an effort to document the SC9830I SoC from the SharkLS SCX35L family from Spreadtrum. The information in this document comes only from public sources, such as the GPL'd source code, datasheets from other chips using the same IP blocks, and experimentation on real hardware. The document is written in the txt2tags format (https://txt2tags.org/). You can build the HTML version by installing txt2tags and running: $ txt2tags scx35l_doc.t2t This will generate the scx35l_doc.html file. If you also have GNU make installed, you can also simply run: $ make It will re-generate the c2000doc.html file only if one of the .t2t files has changed since the HTML was generated.
