4.5.1 Upgrading with Multiple Image Format Files (Firmware
Versions 4.0 & Higher)
Firmware version 4.0 and higher introduces support for Multiple Image Format (.mif)
files. .mif files contain the firmware image (.img) and associated applications and files
to support all the features of firmware versions 4.0 and higher. Firmware versions 4.0
and higher can unpack the .mif file and install the applications and files into the mod-
ule’s flash memory.
Download the .mif file using the command:
•ftp update wifly3-400.mif// For RN131 module
•ftp update wifly7-400.mif// For RN171 module
After downloading the .mif file, the module unpacks it and automatically reboots into
the new boot image with all of the associated files installed into the module’s flash
memory. Ta ble 4 -3 describes these files.
You can verify the firmware image, applications, and associated files in the flash mem-
ory using the ls command. See Example 4-15.
