I can not upload sketch to my UNO directly. My ATmega16U2 doesn't work.But the Atmega328P processor still work. I have an arduino nano lying around. Can I use it to upload sketches to Atmega328P directly. Thanks in advance


Yes. You can. Either as a USB to UART adaptor and use the Uno's bootloader as you would with any bootloader-enabled breadboard Arduino, or as an Arduino ISP to program the chip directly through the ICSP pins as you would when putting the bootloader onto a blank chip.
