Hi There,
I've been unlicky trying to modify Microchip's AN1310 bootloader to be used with USART2 instead of USART1. Did anyone suceed porting thatcode over to be used with USART2?
I have changed all the registers that referred to USART1 to USART2 I believe but still can't get it working.
Help would be appreciated!
Thank you very much!
Ron
