Libertas Boot2 Flash

Getting your Libertas Boot2 Firmware Version

• Install lsusb (in fedora, that would be 'yum install usbutils')
• run 'lsusb -v'
• Look for your Marvell device, it should have these attributes:

 idVendor           0x1286 
 idProduct          0x2001 
 bcdDevice           31.02

• The boot2 firmware version is the 'bcdDevice' field

Flashing from 3102 -> 3104

• Get root
• rmmod usb8xxx
• insmod /path/to/usb8xxx.ko MfgFW=usb8388mfg.bin MfgUpdateBoot2=Boot2_Mfg_3104.img
• Wait until the insmod command exits
• REBOOT NOW

If the insmod keeps running for a long time, say, more than 5 minutes, the process is hung and you will need to reboot and try again.

Flashing from 3104 -> 3102

• Get root
• rmmod usb8xxx
• insmod /path/to/usb8xxx.ko UpdateBoot2=Boot2_Mfg_3102.img
• Wait until the insmod command exits
• REBOOT NOW

Note that the command to back-flash is different than the command to forward-flash
