Official Yocto² Firmware

  • Thank you but I need a .hex or .bin file because I programmed with a TL866 programmer.
    Please upload hex file. Thanks

    Cheers Jos

  • I have a freshly built Yocto2 where the encoder dial doesn't respond. According to posts on the forum, the way to fix it is to reflash.

    I thought I might as well put the new firmware on from this sysex, but neither the 'start+stop' keypresses or the 1+3+5 keypresses mentioned in the user manual bring up any kind of bootloader mode - so how is it possible to transfer this? (Just trying to send the sysex after the Yocto2 has booted up doesn't do anything)

    (for those doing the flash with hex - is it possible with a USB-ASP and avrdude? - if so would anyone mind sharing the correct command?)
  • for programming hex with pickit2:

    avrdude.exe -c pickit2 -p m1284p -P -b -U flash:w:c:\tools_y\Yocto_v2_002.hex:i -v

    fuses:
    avrdude.exe -c pickit2 -p m1284p -P -b -u -e -U lock:w:0x3F:m -v

    avrdude.exe -c pickit2 -p m1284p -P -b -u -U efuse:w:0xFD:m -v

    avrdude.exe -c pickit2 -p m1284p -P -b -u -U hfuse:w:0xDC:m -v

    avrdude.exe -c pickit2 -p m1284p -P -b -u -U lfuse:w:0xD6:m -v

    avrdude.exe -c pickit2 -p m1284p -P -b -U lock:w:0x0F:m -v

    change your file hex destination and choose correct programmer, pls.

    cheers

    Great! That worked, thanks. I used:

    avrdude -c usbasp -p m1284p -U flash:w:Yocto_v2_002.hex:i -v

    ... with a generic ebay USB ASP (all pins except 5v connected, Yocto2 power on). Didn't need to set fuses again. Encoder dial now works. Now awaiting v2.003 hex :)
  • Still no flam with the latest update?
  • Thank you for updating the zip with the hex file :D
  • Thanks for the hex file.

    Cheers Jos
