[j-nsp] EX switch corrupt and stuck in u-loader

[Abdullah Baheer]

Hi
I have an ex switch which got corrupt due to abrupt power off and i tried to recover it from USB flash drive.
Normally the switch would be showing "junos loader' on the switch when it is corrupt.
The problem is now the switch is showing "u-loader" and when i reboot it, it only shows around five messages on the console and gets stuck at "usb:"
This happens weather or not I have a USB flash drive connected.

This output is all i see on my console:

U-Boot
1.1.6 (Feb  6 2008 - 11:27:42)
 
Board:
EX3200-48POE 2.23
EPLD:
 Version 6.0 (0x85)
DRAM:
 Initializing (512 MB)
FLASH:
8 MB
USB:

Has anybody seen this before?

Thanks
Abdullah
