For PIC microcontrollers, a PICkit 3 or an ICD 3 is a typical programmer (which can also function as a debugger, but that is a whole different story.) This aids in writing application firmware since a hard fault followed by a WDT reset will result in the microcontroller safely entering bootloader mode. Bootloaders are often added along side application code to facilitate firmware updates but very few developers truly understand how to build one robustly. Hello. PCB manufacturer writes bootloader into chip before SMT assembly. It can be connected to Arduino UNO board as it comes with arduino bootloader. Big time .
