Hi,

I have three questions:

1. I read on the internet that lpc1769 has uart bootloader. Is it true? How does it work?
2. What is the simpliest bootloader?
3. Is it difficult to make own bootloader?

A search on this forum (sticky thread at the beginning would be a nice way to start) and should reveal some information on the subject also a visit to http://www.lpcware.com could be very productive.
