A SPI-NAND flash programmer software botched together using SPI-MEM and SPI-NAND framework taken from Linux v5.8.
- 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
The default driver.
add the arguments to set CH347 SPI clock (KHz), default is 30000:
# set CH347 SPI clock to 15MHz
-a 15000add the following arguments to select this driver:
-d serprog -a /dev/ttyACM0CH347 dual voltage (1.8V/3.3V) SPI/I2C/UART programmer
Note1: max speed of SPI clock is 30MHz
Note2: CFG0 resistor is not connected

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.
