Atmega168P AU (SMD) Bootloading fail

Other Hardware 3rd Party Boards
1

I am using standard bootloader circuit having 16Mhz oscillator with two 22pf capacitors connected and one 10k resistor with reset (I'll attach my circuit diagram if needed). I am using USB ASP AVR Programmer. I can successfully bootload atmega328p au chip with my current circuit but not atmega168p au. With Atmega328p au I am setting

board > "Arduino pro or pro mini" and processor > "Atmega328P (16MHz and 5V)"

in arduino ide. When using it with 168 I am configuring above setting as

board > "Arduino pro or pro mini" and processor > "Atmega168P (16MHz and 5V)"

but in this case its not working. It gives error

avrdude: Expected signature for ATmega168 is 1E 94 06
Double check chip, or use -F to override this check.
Error while burning bootloader.

Any help would be appreciated.

Turn on verbose uploading (in preferences) and quote more of the resulting errors. (in part6icular, what signature is it seeing?)

The pro-mini doesn't have an ATmega168P. It only has an ATmega168 (the chips are nearly indistinguishable, but they do have different signatures.)

Thanks for reply. Yes its showing that device signature is 168p and i am trying to bootload 168 configuration. Verbose attached below:-

avrdude done.  Thank you.

So what board and processor should I choose for this chip?

The easiest thing to do would be to install "minicore", which has an additional pull-down menu to support the ATmega168P.

Minicore worked!. Thanks a lot for help. Just One more question. I can compile and upload blink code for this board configuration (using minicore), but when i tried my previous code (that i was using with Atmega328p) which has

#include <TimerOne.h>

It gives error:-

C:\Users\Ultron\Documents\Arduino\libraries\TimerOne/TimerOne.h: In member function 'void TimerOne::setPwmDuty(char, unsigned int)':

C:\Users\Ultron\Documents\Arduino\libraries\TimerOne/TimerOne.h:105:13: error: 'TIMER1_A_PIN' was not declared in this scope

  if (pin == TIMER1_A_PIN) OCR1A = dutyCycle;

             ^

exit status 1
Error compiling for board ATmega168.
