OS6465 reboots continuously after trying to upgrade firmware

[mmankollari]

Hello everybody,

I was trying to upgrade the OS6465 firmware from 8.5 version to 8.7 version via ftp.
After saving the configuration and used the "reload all" command, the switch keeps rebooting continuously, making it impossible to access it via console port. Tried to reset it using the USB method on Marvell mode and I get this error:

Marvell>> run rescue
(Re)start USB... USB0: Port (usbActive) : 0 Interface (usbType = 2) : USB EHCI 1.00 scanning bus 0 for devices... USB dev 1, u-boot EHCI Host Controller device is a hub, probing
1 USB Device(s) found
scanning usb for storage devices... 0 Storage Device(s) found
scanning usb for ethernet devices... 0 Ethernet Device(s) found
No storage devices, perhaps not 'usb start'ed..?
** Bad device usb 0 ** Wrong Image Format for bootm command

Any idea how to fix this issue?
Any help would be appreciated!
