Deal all,
recently I’ve started a small project based on SAMD21 with help of ARDUINO IDE 1.8.3. To get started with this controller, I utilized the Arduino ZERO board for my first steps.
The long start-up time (cold start 2sec, warm start 0.5sec) until first opcode of setup() is executed is an issue for my application. I’ve measured the timing delays with reference to rising edge of SAMD21 RESET signal.
How can I shorten the start-up time? Why start-up time differs between cold and warm start?
Thanks in advance.
