How to update a firmware

(Method tested on Linux, should work on any OS where dfu-util works, instructions assumes you have dfu-util 0.9)

Warning: This potentially can brick your device. Do on your own risk!
Warning: Author of these instructions successfully dumped a firmware, bricked the device with a custom firmware and flashed stock dump back.


  1. Enter an update mode. For that plug USB cable while holding *-* button (button, that's closest to USB-C port)
  2. Make a firmware backup: dfu-util -d 28e9:0189 -a 0 -U ~/pinecil/internal.flash.stock -s 0x08000000
    1. 28e9:0189 -- USB Device ID (can be obtained from `lsusb` or `dfu-util -l` but in dfu-util output it might be hard to identify the Pinecil device)
    2. -a 0 -- selects what to flash. List of possible options can be obtained via `dfu-util -l`.
    3. `-U` -- specifies a mode. U is upload, which means that firmware will be downloaded and saved to file (yes, that's confusing, but it is what it is, feel free to verify that in a manual of your version of dfu-util). Command must be followed by a path to file where you want to save your firmware. dfu-util will refuse to dump firmware if you already have a file with that name.
    4. -s 0x08000000 -- specify the address in a flash from which dump will start. This can be obtained from `dfu-util -l`.
  3. Flash a new firmware: dfu-util -d 28e9:0189 -a 0 -D ~/pinecil/internal.flash.stock -s 0x08000000:mass-erase:force
    1. -D -- is a mode to Download firmware to the device (yes, that's confusing, but you indeed Upload from device and Download to device with dfu-util). That should follow the file with the firmware Same stock one from (1) used here on purpose.
    2. -s 0x08000000:mass-erase:force -- specified the address where to flash the file. `:mass-erase:force` is required to force-erase flash before updating firmware, otherwise you might have unpredictable results.
