Update Mega328 Transistor Tester with Arduino Uno micro controller

Hello,

I’m trying to update Mega328 Transistor Tester with Arduino Uno micro controller.

Here is my Uno and Mega328 connection and Avrdude setting, including particular error:

avrdude.exe: verification error, first mismatch at byte 0x7e00
** 0x11 != 0x41**
avrdude.exe: verification error; content mismatch

I’m not sure what is wrong
