ISP Pins do not match AVR328P #18

Hi Community

On referring the LQF8 Nano schematic https://github.com/nulllaborg/arduino_nulllab/blob/master/doc/LGT328P-LQFP32-Nano.pdf I see the pins for ISP programming not matching the ones on the original 328P

Please let me know the wiring connections as well as the software settings needed to be done to upload firmware via USBASP which has MISO,MOSI,SCK and RST pins for programming

Help is much appreciated

I don't think it's possible to use USBASP to do the job here. I'm sure you can use another Arduino as ISP programmer for the LQF8 Nano, as described here or here.

The second repo contains source code and hex file on how to make the conversion.
