Hi All,

Is there a way to remove the "further programming disabled" Lock bit
to "No Memory Lock feature enabled" in AVR ATMEGA88.

Thanks

probably is - the current price to read FULLY PROTECTED atmega8 is 800
RMB,
I dont know the price for atmega88 reading but I am guessing it is not
more then 1000 USD

if you want to change lock bits 'non intrusive" then this may however
be not possible.

no as in the lock bits are set to "further programming and
verification disabled" now i want to upgrade the firmware. is that
possible?- Zitierten Text ausblenden -

if programming is disabled then you can:

1) erase chip and reprogram it with new firmware
2) write your own updater and use it (if self programming is enabled)
