SPI FLASH is a lightweight utility for interacting with serial flash memory over SPI. It helps engineers, technicians, and hobbyists identify chips, back up firmware, erase, program, and verify contents with built‑in safeguards. Ideal for tasks like BIOS updates, firmware recovery, and embedded development.
Key features:
- Automatic device identification via JEDEC IDs (with SFDP parsing where available)
- Read, erase, program, and verify operations
- Full‑chip or region‑based access (address ranges and selective sectors)
- Post‑write verification with checksum/CRC and file/device diff
- Support for common image formats (BIN, Intel HEX)
- Status/lock bit handling and write‑protection controls
- Bad‑block–aware operations for supported SPI NAND devices
- Adjustable SPI parameters (clock rate and delays) for reliable programming
- Detailed logs, progress reporting, and retry logic
- Read‑only and dry‑run modes to minimize risk
Typical uses:
- Backing up and restoring firmware from SPI flash
- Updating motherboard/UEFI/BIOS chips
- Programming bootloaders for routers, SBCs, and IoT devices
- Recovering bricked devices and validating production programming
Hardware notes:
- Designed to work with common USB‑to‑SPI programmers and GPIO‑based adapters; specific device compatibility may vary
- Requires physical access to the target chip (e.g., SOIC clip, socket, or in‑circuit connection)
Best practices:
- Always create a verified backup before erasing or programming
- Match the image to the exact chip and device model to avoid incompatibilities
Use SPI FLASH to streamline reliable, repeatable SPI memory workflows from prototyping to repair.
