/usr/local/bin/ioflashstoragetool
This tool seems be present in restore ramdisks for formatting NAND flash.
Usage
ioflashstoragetool: Low-level NAND flash utility
Options:
--verbose Be talkative about what the tool is doing.
--noisy Be extremely noisy while doing things.
--quiet Don't show progress output.
Multi-bank addressing:
p<page> Addresses all banks, starting at bank 0, page <page>.
b<block> Addresses all banks, starting at bank 0, block <block>.
In these modes, page/block counts are per-bank and all operations start
at bank zero. <page>/<block> may be decimal or hex preceeded by 0x.
Single-bank addressing:
<bank>p<page> Addresses bank <bank>, starting at page <page>.
<bank>b<block> Addresses bank <bank>, starting at block <block>.
In these modes, page/block counts are for the selected bank only.
<bank> is decimal, <page>/<block> may be decimal or hex preceeded by 0x.
Commands:
format <partition table type>
Writes partition table to pages 0 and 1 of block 0 of all devices.
The <partition table type> may be one of: s5l8720x s5l8920x
--force Performs format even if an AND signature is
detected.
