Thanks for the detailed answer, that's reasonable enough. Two more question
popped into my mind in this subject:
1. Let's say you have that programming connector or that hole that you are
use for the purpose. Is not that makes easier for anybody to hack your
product -- or who cares about that?
2. Can you use the in-circuit serial programming to store data onto the
program memory area? I mean that your firmware / bootloader / whatever
decides to put or change data which is semi-permanent / semi-constant. (I
know, use EEPROM, but just wondering...)
Thanks
