Hi,
Ive been trying to build a custom Teensy 3.6, however it is non responsive. The 3.3V supply generated seems good. When pressing the program button I can see both the reset and program signal lines being pulled low.
Attached is the schematic my board uses, I know it's not drawn the best, but if someone could check it over for any obvious mistakes that would be great. When plugging into a PC the first time it makes the sound of a recognised USB device, then after pressing program it never seems to make any sound again. I've built a couple of the PCBs to try and narrow down any bad solder work. Any further troubleshooting suggestions would be great. Thanks.
I've used the following crystal:
EPSON 16MHz Crystal Unit ±10ppm TSX-3225 4-Pin 3.2 x 2.5 x 0.6mm
