SG300 Marvell U-Boot

[Gate Swan]

I have a SG300-10 that is booting to Marvell U-Boot and then into a testing mode. Is there anyway to recover from this? I have not been able to find anything helpful online.

I had the same issue with a SF302-08.

I did following:

1. Boot the device

2. Wait for the test mode

3. Press N (Not documented option)
   Following menu appears:
   # '0' - Turn on Burn-In flag ; '1' - Config Burn-In parameters 
   # '2' - Show Burn-In information ; '3' - Show flash information 
   # '4' - Turn off Burn-In flag

4. Choose Option '1' - Config Burn-In parameters 
   Following appears:
   # Set Power cycle ...
   # Cycle range: 0001 ~ 9999 
   # Input Power cycle: 

5. Power cycle the device without enter a number

6. The device boots with the Cisco image

Makes no sense but it works in my case.
