Hello guys, I am doing a project on 'boot loader for the PIC soder test PCB'.
Could anyone solve my questions please...

Well, I need to write a boot loader code for PIC18F1320 and then need to transfer a PIC program into it which should be implemented using boot loader.


1. In general, which language we have to use for writing bootloader code and which format does the PIC support?
2. I found some bootloader codes with .h, .s, .exe, .bin, .bib extensions? wat r all these?
3. What are the possible ways to transfer a bootloader code into PIC?
4. Why do we use hyperterminal? I mean is it to transfer the bootloader code or user program?
5. If we need to run two applications using boot loader, what they could be?
6. How to reprogram if there is any error in the user code or boot loader code?

well almost anything that can update itself has a bootloader. Like many modems and routerss can be upgraded and have bootloaders. Many Gaming Systems, mp3 players etc.... Bootloaders are basically for ease of upgrade or reprogramming.

Since the general public doesnt have the knowledge or tools to program a uC themselves. Bootloaders let them simply plug in via USB or Download direct update and just press a button to install new firmware updating the device.

Good reading here:
