How does that relate to your statement in the fist post;I was actually responding to this;
Check the pinouts of the 328P vs 328PB again.
Thank you for the help. I am using UART to upload sketches to my project board. And no matter that 328p or 328pb they are both using the same pins for uploading sketches. I seriously checked their differences but that doesn't affect the failure i think.
