Hi,
I have an evk1101 board for UC3B0 development. The chip on the board has been accidentally locked (Security Bit is set, memories are locked). I've tried to erase the chip by using AVR prgramming tool of both avr studio 5.0 and 5.1. Both tools fail to erase when using avr jtag ice mkII, or dragon.
The following error message is given by the avr programming tool (of 5.1):
Timestamp: 2012-03-29 09:33:18.127
Severity: ERROR
ComponentId: 20100
StatusCode: 1
ModuleName: TCF (TCF command: Device:erase failed.)
An unknown error occurred on the debugger. Debugger command Erase failed.
Is there some (other) way to erase the chip and get the evk board back in use? |

I solved a similar problem by using AVR32 Studio to "Erase Chip"
In AVR32 Studio Load a sample project
In AVR Targets
Scan Targets
Once you have the Debugger set up
Right click on the target debugger and click on "Chip Erase"
If it fails power down the target and the Debugger, power the debugger back on then the target and try it again.
This worked for me when it would not erase a chip in Studio 5 or 5.1 or 6 Using JTAGICE3 and AVR ONE and JTAGICE MKII or DRAGON
AVR32 Studio seems to erase chip differently when all other Studio versions simply keep reporting obscure useless errors. |

Thank you for the tip.
For some reason, the same didn't work for me. I give up and will just buy a new one. |
