i am having a similar issue using a pic18f4580 chip. everything programs fine but i get a timeout when i try downloading the application .hex file or simply search for the bl. my code is basically exactly the same as the previous posts except i noticed that the configuration bits in MPLAB includes a boot block size select that must be 1 KW or 2 KW. would this be effecting the programming and functionality of the bootloader?
i also have an external 4MHZ oscillator i could be using but in trying to copy the functionality of teh previous posts i used the inter RC oscillator with the added code:
i know my serial communication works fine because i use it in my application firmware
any thoughts?
