981213 / spi-nand-prog

A SPI-NAND flash programmer botched together using kernel SPI-NAND framework. Works with stm32-vserprog or WCH CH347.

SPI-NAND Programmer

About

A SPI-NAND flash programmer software botched together using SPI-MEM and SPI-NAND framework taken from Linux v5.8.

Features

• Reading/Writing SPI NAND
• Operations with on-die ECC enabled/disabled
• Operations with OOB data included or not
• Skip bad blocks during writing
• Data verification for writing when on-die ECC is enabled

Supported devices

WCH CH347

The default driver. No extra arguments needed.

dword1511/stm32-vserprog

add the following arguments to select this driver:

-d serprog -a /dev/ttyACM0

Usage

spi-nand-prog <operation> [file name] [arguments]

Operations: read/write/erase/scan
Arguments:
 -d <driver>: hardware driver to be used.
 -a <arg>: additional argument provided to current driver.
 -o <offset>: Flash offset. Should be aligned to page boundary when reading and block boundary when writing. default: 0
 -l <length>: read length. default: flash_size
 --no-ecc: disable on-die ECC. This also disables data verification when writing.
 --with-oob: include OOB data during operation.
