An open-source book on storage technology and file systems. From knot records to Flash physics, from FAT to LittleFS — complete with KnotFS, a teaching-grade log-structured embedded file system (~1770 lines C).
OpenFlash is an open-source NAND/eMMC/NOR flash programmer that turns cheap microcontrollers ($4 Raspberry Pi Pico, STM32, ESP32) into full-featured flash memory readers/writers.
Feature-rich DWIN display library — portable C core for Arduino/ESP32/STM32, low-SRAM text I/O, VP R/W, CRC16, RTC, NOR, graphs, overlays.
Provides the W25Q128J driver, part of the STM32Cube BSP Component for all STM32xx series.
Cross-platform desktop tool for reading, validating and archiving NOR flash dumps from gaming consoles. Features UART error code reading for live diagnostics and DualSense controller testing. Built with Tauri v2 (Rust + Svelte 5). UI available in German and English.
PS5 Slim HDMI chip repair tool: patch PS5 NOR flash (.bin) to swap Realtek RTD2175P for Nuvoton/Panasonic MN864739 (or back). Read/write NOR via CH341A programmer. Companion to the DatZero HDMI Interposer.
UT8QNF8M8 NOR Flash Controller VHDL Module
A Rust reimplementation of minipro (CLI and GUI).
Wear-leveling volume manager for raw NOR flash on Zephyr RTOS, with authentication (AES-CMAC via PSA Crypto).
Provides the STM32Cube MX25R3235F BSP Component Driver, common to every STM32Cube MCU firmware that supports it.
Provides the MX25UW25645G driver, part of the STM32Cube BSP Component for all STM32xx series.
Provides the MX25UM51245G driver, part of the STM32Cube BSP Component for all STM32xx series.
Wear-leveling volume manager for raw NOR/NAND flash on Zephyr RTOS, with optional authenticated encryption (AES-128-CCM via PSA Crypto).
🏆 集创赛「胜达克」企业命题｜西南赛区一等奖 · 全国总决赛一等奖｜AT24C02 初赛 · BY25Q40AL 复赛 · 全国总决赛 PAT 软件
Provides the MX66UW1G45G driver, part of the STM32Cube BSP Component for all STM32xx series.
Bare-metal SPI NOR Flash driver for STM32F103, implemented in C using register-level programming.
Deterministic transactional filesystem for embedded NOR flash, built so persistent state survives power loss, interrupted erase, and firmware rollback.
no_std Rust driver for the ISSI IS25LP128F Quad-SPI / SPI NOR Flash memory
Deterministic C++20 simulator for NOR flash power-loss and crash-consistency testing.
