README
README.mdClogger — Minimal Linux‑Powered USB eMMC Reader (F1C100S) Clogger is a tiny, reproducible hardware project built around the Allwinner F1C100S, designed to read, clone, and analyze BGA153/BGA169 eMMC chips using nothing more than a Linux system running from an SD card. The goal is to create a fully open, hand‑solderable tool that exposes an attached eMMC device to a host PC over USB — just like a USB mass‑storage adapter, but built from scratch.
🔧 Goals
*Build a minimal F1C100S board that boots Linux entirely from an SD card
*Provide a UART‑accessible Linux shell for debugging and control
*Use USB gadget mode to expose the connected eMMC as a block device
*Support BGA153/BGA169 eMMC reballing using low‑cost stencils and solder paste
*Offer a fully reproducible Buildroot toolchain (U‑Boot + kernel + rootfs)
*Document the entire bring‑up process: boot flow, device tree, SD layout, and USB configuration
*Create a simple, reliable tool for eMMC backup, cloning, and recovery
29.12.2025 Work on first hardware version started
31.12.2025 Added 3D models, added LEDs (for work without terminal), added decoupling capacitors, added line resistors

Questions
How big is the EMMC dumper PCB?
It measures 60.4 × 36 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EMMC dumper use?
67 parts, built around the F1C100S, AMS1117-3.3 and EMMC04G-M627-A01. 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 EMMC dumper KiCad files?
From the bartuss12/Clogger repository on GitHub, at the commit this page was made from: the board is hardware/eMMC dumper.kicad_pcb and its schematic hardware/eMMC dumper.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EMMC dumper design in my own project?
Its repository states no licence, so its author keeps all rights: ask bartuss12 before reusing the design.
