Hello Sirs,
I would like to ask how to burn the bootloader on the Arduino Due?
I’m asking this because I’m worried that I might damage the bootloader while testing the Arduino Due.
Previously, when I was testing the Arduino Zero, I accidentally damaged its bootloader and was able to reburn it using the Arduino IDE.
I learned that the bootloader on the Arduino Due is installed in ROM. Does this mean the bootloader on the Arduino Due cannot be damaged? So I don't need to worry about this situation?
Hello everyone,
I’d like to know if the bootloader on the Arduino Due can potentially be damaged?
Previously, I uploaded my blink sketch to an Arduino Zero but received the following error: Error: at91samd21g18.cpu -- clearing lockup after double fault. Afterward, I was able to get the Arduino Zero working again by reburning the bootloader, so I believe I had damaged its bootloader at that time.
Now I’m worried that I might encounter a similar issue when uploading my blink sketch to the Arduino Due. If that happens, will I still be able to reburn the bootloader? Or are there other solutions?

I don't have an answer to your question.
Roger that.
That should be the case.
I suppose you could damage the pins that are needed to cause the SAM3 chip to enter the bootloader, but it wouldn't be easy!
Then I hope I won’t damage those pins. 
Thank you for your reply.
