Hi,

I bought a GM328 transistor tester that can't be calibrated. It stucks 
at the "short probes" stage. Anyway, I decided to update the MCU 
firmware.

I connected the ATMega328pu to my breadboard and I double checked the 
connections with my DMM. The AVRdude always return the following error :

1
D:\temp\GM328\EN>avrdude -pm328p -cUSBasp -B4 -Pusb

2


3
avrdude: set SCK frequency to 187500 Hz

4
avrdude: warning: cannot set sck period. please check for usbasp firmware update.

5
avrdude: error: programm enable: target doesn't answer. 1

6
avrdude: initialization failed, rc=-1

7
         Double check connections and try again, or use -F to override

8
         this check.

avrdude done.  Thank you.



I even tried to connect an external crystal but without luck. What seems 
to be wrong here? My OS is Win10/64Bit and AVRdude is v5.10

Regards,
