The physical space of the NAND Flash memory is divided into multiple blocks, each of which is
subdivided into multiple pages. The NAND Flash memory is erased on a block basis and read on a
page basis; the memory spaces are allocated on a page basis.
Displaying and repairing bad blocks
Bad block ratio varies with products of different vendors. Bad blocks cannot be used to store data, and
the system has to skip the bad blocks when it allocates storage spaces to files. You can get the locations
of bad blocks and repair them at the CLI.

Task Command
Display the space distribution of the specified file in
the NAND Flash memory
display nandflash file-location filename [ | { begin |

Performing batch operations
A batch file comprises a set of executable commands. Executing a batch file is the same as executing the
commands one by one. However, execution of a batch file does not guarantee successful execution of
every command in the batch file. If a command has error settings or the conditions for executing the
command are not met, the system skips this command.
You can edit a batch file on your PC, and then upload or download it to the device. If the extension of
the file is not .bat, use the rename command to change it to .bat.
