Use original IC after Firmware Update

 

Hi, I try to upgrade the firmware of my gcx mini, and mess up the fuses.
?
after I corrected it to avrdude -c usbasp -p m328p -U lfuse:w:0xF7:m -U hfuse:w:0xD1:m -U efuse:w:0xFC:m
?
It shows the use original ic on screen :(
?
Is there a trick i can do, to bring it back to life?
?
Regards ?Andreas / OE9ROE
 

Hi Andreas. That issue you had with the fuses most likely deleted the EEPROM file. That file is proprietary ?and not published. You will probably have to order a new chip from QRPLabs to get going again...

Sorry ... Ron
