 JFFS2 File Systems

Katana®752i User’s Manual

This section describes the commands for the read-only JFFS2 file systems. These com-
mands assume a valid JFFS2 file system in Flash with support provided for two partitions: 

• Base of partition 0 is 0xE8180000

• Base of partition 1 is 0xE8000000 + (Total_Flash_Size/2) + 0x180000

The ls command lists the files in the directory. 

ls [directory] 

The fsinfo command prints information about file systems. 

fsinfo 

The fsload command loads the binary file from the Flash bank with offset of ‘off’. 

fsload [off] [filename]

The chpart command changes the partitions (partitions 0 and 1 supported). 

chpart [part] 

The memory commands allow you to manipulate specific regions of memory. For some 
memory commands, the data size is determined by the following flags:

.b

This is for data in 8-bit bytes.

.w

This is for data in 16-bit words.

.l

This is for data in 32-bit long words.

These flags are optional arguments and describe the objects on which the command oper-
ates. If you do not specify a flag, memory commands default to 32-bit long words. Numeric 
arguments are in hexadecimal.
