Tiny bootloader and pbp

[Dave]

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 ?

;----- CONFIG5L Options --------------------------------------------------  
    
    CONFIG CP0       = ON         ;  MEMORY BLOCK 0 CODE PROTECT BIT - 7KW 800h  - 3FFFh ( when 1K BOOT OPTION used )

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.
