I don't think it's because of the CH340 chip, because all the other nanos I use have this chip and are working fine.
Here is the wiring I used for my last answer:
NanoA -- NanoB ICSP connector
D13 -- 3 (SCK -- SCK)
5V -- 2
GND -- 6
D10 -- 5 (SS -- RESET)
D11 -- 1 (MISO -- MISO)
D12 -- 4 (MOSI -- MOSI)
