Microcode bootloader using PIC18F4680
Posted: Sun Jan 25, 2009 9:57 pm
Hi.
I decided to try the Microcode bootloader a try weekend using the 18F4680, this chip suffice for now as I’ve only just crossed the 32K ‘boundary’ so no immediate need for the 18F4685 that I have been using.
IN MPLAB IDE (Vn8.1) my program is ORGed to start at $400, viewing the program memory window this can be seen (it presently ends at $8078). But when I open the same file using the Microcode bootloader the code is clearly seen to be set at the wrong address of $200. I have closed/ re-opened both MPLAB & Microcode several times but the error is persistent, the only I can get it seen in Microcode at the desired address is to ORG my program $200 locations further down, but obviously this is not a practical way of programming. Is this a bug or just a limitation on the free software that will not be seen on the purchased package?
Regards, Mark.
