| #RDA does not work with Bootloader include |

Hi guys, I am trying to develop a program in CCS Compiler Version 5 on RS232 communication between two PIC 18F4550 and 18F4620 I use #RDA interruption for the reception and it works very well except that I a problem when I included the "Bootloader.h" in this case the bootloader works well but it causes me a problem at #RDA because it does not work.
All work well without include bootloader.
Please a solution to this problem ...
This is my CCS prog:
| Code: | #include <18F4620.h>
#device ADC=10
#FUSES NOWDT //No Watch Dog Timer
#FUSES WDT128 //Watch Dog Timer uses 1:128 Postscale
#FUSES FCMEN //Fail-safe clock monitor enabled
#FUSES IESO //Internal External Switch Over mode enabled
#FUSES PUT //Power Up Timer
#FUSES NOBROWNOUT //No brownout reset
#FUSES BORV21 //Brownout reset at 2.1V
#FUSES PBADEN //PORTB pins are configured as analog input channels on RESET
#FUSES LPT1OSC //Timer1 configured for low-power operation
#FUSES MCLR //Master Clear pin enabled
#FUSES STVREN //Stack full/underflow will cause reset
#FUSES NOLVP //No low voltage prgming, B3(PIC16) or B5(PIC18) used for I/O
#FUSES NOXINST //Extended set extension and Indexed Addressing mode disabled (Legacy mode)
#FUSES NOPROTECT //Code not protected from reading
#FUSES NOCPB //No Boot Block code protection
#FUSES NOCPD //No EE protection
#FUSES NOWRT //Program memory not write protected
#FUSES NOWRTC //Configuration registers not write protected
#FUSES NOWRTB //Boot block not write protected
#FUSES NOWRTD //Data EEPROM not write protected

First, the _bootloader_ needs all the fuses. Get rid of them in the runtime. Personally I use #fuses NONE in the runtime code. You can't change fuses in the application, from what the bootloader has.
Then your interrupt is fundamentally flawed. INT_RDA, means _one_ character is available. Just one. Do a search here for why you should never use gets in the interrupt. I'd suspect your failure is actually caused by the extra delay on boot, and the interrupt not functioning as you expect, rather than the bootloader itself.... |
