I’m trying to program an attiny84 on a custom board. For experimenting I’m using the blink sketch from the basic examples. I’m using an arduino nano with the arduino as isp sketch, and the 1.0.5 IDE.
I’m able to upload blink to the 84 using the IDE, however, when I try using the command line
avrdude -p attiny84 -c arduino -P com23 -U flash:w:blink.cpp.hex -v -v -v
I get the following error:
avrdude: stk500_getsync<>: not in sync: resp=0x00
any idea what I may be doing wrong?
