Hi! Thanks for this bootloader!
I have compiled for 18F442 and it works good, but now i have a problem.
In my circuit i have add new device wich is connected to RE0, RA4 and RE2.

The first time the bootloader answers and i can write an new hex file, but the new image is not working. After a restart the bootloader doesnt answering anymore and the new firmware doesnt work.

Befor i attached the new device, all works perfect.

Thank for your help!

#include "p18f442.inc" IdTypePIC = 0x41 #define max_flash 0x4000 xtal EQU 20000000 baud EQU 115200

Fixed!

#include "p18f442.inc" IdTypePIC = 0x42 #define max_flash 0x4000 xtal EQU 20000000 baud EQU 115200

IdTypePIC must set to 0x42.

Here the files, now it works perfect.
I have modified the code, so PIN RA5 go's high and indicate, that the bootloder is running.

18F442_20Mhz_115200.HEX

18F442_20Mhz_115200.asm
