Hi, I was uploading a program with Arduino app from Mac os X to my Arduino uno (ATMEL MEGA 328P CH340G chinese clone) and the program was too much big. I try to reduce the program, but when I try to upload again to arduino, all time wrong. It says avrdude: stk500_recv(): programmer is not respondin…

Bricked or something like with Arduino UNO

I suspect that you have managed to (partially) overwrite the boot loader. You will need to burn the boot loader and see if that fixes the issue.
