    Teensy 3.5 diy build with MK64FX512VLQ12

    Hi,
    We have been using the teensy 35 board for a while and I'm now at a point where I really need to build my own teensy 35 on a custom board. I'd like to keep the board layers down to minimise cost of fabrication so have decided to select the leaded devices.

    I've based a design around the IC_MKL04Z32_TQFP32 (purchased from PJRC) and the MK64FX512VLQ12.

    Its a shame there is no single source of collated information for carrying out these builds but I have read the notes and linked posts found from the following link.
    https://www.pjrc.com/store/ic_mkl02.html

    I've had the PCB board built based on the schematic attached, but after assembly it hasn't worked. I've checked the soldering and buzzed out the connections.

    Would someone be able to confirm if I've made a simple mistake in the design? If it looks ok I'll have to dig a bit deeper into fault finding the actual board.

    really appreciate any help.

    cheers
