Tiny bootloader and pbp

[longpole001]

the bootloader pc app does not see the bootloader code serial port - untill it does the other steps are mute

i have removed my config and just used the base standard 18f87k22 chip confg - 16mhz internal , no PPL4 , no protection etc
build asm with MASM 5.86 , with options as build in absolute mode , it has the correct hex format INHX32

i have serveral other chip set of 18f46k80 , 18f47k40 to make this work on

I have the referance dave given me for the 18f46k80 series , will need a k40 version

so have built that with the default chip config setting for the 18f46k80, usart 2 19200 ( for this device)

THE BOOTLOADER PC SOFTWARE SEE IT "Yay" on manual reset
and it bootloader pc software finds the base code config

so ill continue to work on 18f46k80 bootloader and put in my chip config

I am still unclear what changes i need to make to my orignal pic code for the bootloader to allow it to work

this is going to be long project stage i think

cheers

Sheldon, The only statement required for PBP is the "DEFINE LOADER_USED 1" at the top of the program.

thanks dave


prior to bootloader use and relating to the config of the pic protection memory blocks i had protected boot blocks
and most of memory blocks

which of these now cant be protected cos of the bootloader use ?

which setting can be further locked down if using a bootloader ?

Sheldon, This is the sheet for the 18F47K40 that I use here.

[longpole001]

dave have you the asm code for MPLABX for the 18f27k40 used for the tiny bootloader

i think as i am using the 47k40 theword values will be abit differnet

[Dave]

Sheldon, Here is the .asm file I use here.
