SFUD is an open-source universal driver library in C for serial SPI/QSPI flash chips, based on the JEDEC SFDP standard parameter table. It abstracts differences between flash manufacturers so one codebase can read, write, and erase many flash models, with a fallback parameter table for chips lacking SFDP support.
Use cases
- drive different brands of SPI flash with one portable driver
- support flash chip swaps without code changes when parts go end-of-life
- read and write firmware images stored on external SPI flash
- build a flash programmer/burner tool
- access QSPI flash on an MCU with 4-byte addressing
- add flash storage to an embedded product with minimal RAM/ROM budget
When to choose
- you are writing bare-metal or RTOS C code for an MCU with SPI or QSPI flash
- you need to support multiple or unknown flash chip models via SFDP auto-detection
- resource footprint matters (under 1KB RAM, a few KB ROM)
- you want MIT-licensed, easily trimmed driver code
When to avoid
- you need a filesystem layer on top of flash rather than raw read/write/erase
- your storage is eMMC, SD, NAND, or parallel flash rather than serial NOR SPI flash
- you work in a higher-level environment (Linux has its own MTD/SPI drivers)
- your chip lacks SFDP and is not in the built-in parameter table and you cannot add it
