- // File: 18f87j50.lkr
- // Sample linker script for the PIC18F87J50 processor
- // THIS LINKER SCRIPT HAS BEEN MODIFIED... This version is intended to be used
- // with the "PROGRAMMABLE_WITH_USB_HID_BOOTLOADER" bootloader. The HID
- // bootloader occupies memory ranges 0x000-0xFFF. In order for the code generated
- // by this project to work with the bootloader, the linker must not put any code
- // in the 0x00-0xFFF address range.
- // This linker script was originated from the 18f87j50.lkr file provided by
- // the MCC18 distribution.
- // NOTE: As configured by default the HID bootloader does not erase or attempt to
- // program the last 1024 byte block of program memory (because this flash memory
- // block contains the flash configuration words).
- // Erasing and reprogramming the configuration words is "slightly dangerous" in that
- // it is possible to bootload incorrect configuration bit settings that will
- // prevent both the application and bootloader from working properly (ex: incorrect
- // oscillator configuration settings, which are incompatible with USB operation).
- // The bootloader does allow the user to override this behavior however, and the
- // last 1024 bytes of program memory (including config words) may be both
- // erased and programmed, if the user is careful.
- // However, by default, the last 1024 bytes of program memory are not
- // erased or re-programmed. Therefore, the last 1024 bytes of program memory
- // have been marked PROTECTED in the linker script, to prevent the linker from
- // "accidentally" placing code in this region.
