Make two cope snippets in the boot loader to:
1. Toggle led when data is received on rx
2. Send data on tx when a button is pressed or similarly.
This way you can see if bot rx and tx is not working
Yes UART1 works in my application.
I have tried turning off TXIE just in case that was the problem, but no change.
In bootloader, I can toggle an led on when receive using USART2, but when i try USART1 the led doesn't toggle on, suggesting USART1 not turned on or some other conflict
