Starting with address 4h in flash, resides a GOTO USER_CODE_START instruction. This is the first instruction executed by the MCU. This means that the size of the bootloader is 768 bytes or 384 words.Īt address 0-3h in flash is placed the GOTO BOOTLOADER_START instruction. The bootloader code is placed in flash memory at address MAX_FLASH - 300h. No need for a hardware programmer like PICkit to download your code in the MCU, if the bootloader is already flashed in your MCU.The source code from this repo is configured specifically for the PIC18F25K22 device, but with minor modifications it can be adapted to other PIC18xxKxx devices. ![]() The code is written in assembly and compiled with the Microchip's MPASM assembler. This project is a bootloader for the Microchip PIC18 XLP(PIC18xxKxx) devices family, that allows users to download code into the MCU via the UART interface.
