Hi All, I am software engineer. I am new to hardware design but I have used Eagle quite a few times for simple circuits. Now I want to design a board which should have following things on it. 1. ARM-CortexM4 based MCU 2. Few peripherals for ADC conversions and DAC conversions. Also how do I use bootloader? Can somebody help me with what all are the detailed steps to do this?
