[avr-chat] Can't erase Tiny2313?

[Bob Paddock]

 

I have several boards with Tiny2313's on them, with currently
running code, working fine.  They are using a 4 MHz resonator.
They have the lock bits set to "Future Programming and
verification disabled".

Using AVRStudio 4.14.584 and STK500 when I "Erase Device", the
STK500 says that it did, no errors.  However nothing seems to
have changed.  The signature remains 0x00 0x01 0x02 and the lock
bits are still set.  The old program is still running.

I thought erasing the device undid the lock bits?
