I've been successfully programming some ATTiny85-20PU with a self built programmer and Arduino Nano. These are the DIP package version.
I recently changed my design on my target board to use a surface mount equivalent, the ATTiny85v-10SH and now I'm getting invalid signature and programming fails.
Did I miss something? Is the surface mount version somehow different?
I'm using the internal oscillator/ 1Mhz.
My programmer has a ZIF socket which I dropped the DIP version into. I took a DIP socket and soldered a mini molex connector that goes to a female molex programming header on my target board. I've checked continuity pin for pin from the socket to the surface mount chip, its fine.
Here's the output:
Arduino: 1.8.7 (Windows 7), Board: "ATtiny25/45/85, ATtiny85, Internal 1 MHz"
