Hi PJRC Team,
First of all I would like to mention that I find the Teensy project a very competitive solution for develop arduino projects. I have used teensy 3.2 for many projects, and I found a need to implement a "Custom Teensy", for a project that requires adding multiple components and reducing the final weight. I tried to do it by using using the MKL04 chip with pre-programmed Teensy LC & 3.2 bootloader, and following many reference circuits I found on the web.
My PCB actually is recognized by the PC, and allows me to program the blink example. However, when I restart my PCB, it does not do anything. The only way to get the led blink firmware to run again is to press the PROGRAM button, and connect USB cable to computer. I need the PCB to be programmed once, then I don't need more to connect any computer, I understand that the MKL04 task is to load the HEX and interface the Arduino software, but:
Does it program the firmware everytime it restarts?
Is it possible to program this once and leave unconnected the USB for future restarts?
Thanks,
