    great can you comment on the PR as such, as they seem reluctant to add that and it is required.

    I have submitted a PR to the MTP github to fix this properly.
    The issue is actually in MTP.h OpenFileByIndex which should use oflag_t rather than a byte.

    This seems to be fixed differently in the most current Teensyduino usb_desc.h and works without this change (which actually will fail).

    Yes it is fine with me, can you send me a pull request so i can update my version with the version that works? thanks

    yea it needs to be put in flash not ram, the compressed one has the magic incantation for that.

    no I never got it to work, which is why I suggest you use the uncompressed version. I did write a verifier for it though and it compares byte to byte with the original.
  13. no that is unrelated, I think you can ignore...

    no that is unrelated, I think you can ignore those errors as they follow a reset and probably the chip is not ready yet.
  14. yea one is compressed the other is not...

    yea one is compressed the other is not compressed, you can use the uncompressed one as the 1280 has more flash available.

    The issue is that the standard routine to read flash can not handle 24...

    Yea it is related, you need to make the mods he has suggested, as reading from Flash is not as straight forward as I had thought. It runs on teensy as there is no special program needed to read flash.

    FYI I have not tested it on a teensy though, but it should work :). the FT5x06 is much easier because they actually document the chip, whereas the makers of the GSL1680 decided to not release the...

    well this would work on an arduino, except the firmware is too big to fit in the flash of a Uno, it should work fine on a teensy3 or teensy++ though.

    Teensy3 stopped responding

    Hi, I just got my Teensy3. It was working really nicely and had it hooked up to a 3.3v IMU, and everything seemed to be running smoothly.
    Then suddenly everything stopped.
