* <2016-11-12 Sa> - Solder Merkur Boards 
  as of https://github.com/tijuca/lowpan-pcb-designs in Fr
* <2016-12-04 So> - Flashed [bonsai bootloader](https://github.com/osdomotics/osd-hardware/tree/master/bootloaders/atmega-bonsai)
  Several boards won't accept a second stage bootloader afterwards, reason yet unknown
  [[file:merkur-board-flash-1st-stage-1.jpg]]
  [[file:merkur-board-flash-1st-stage-2.jpg]]

  Steps:
  - Connect AVR Dragon
  - Supply 3.3V Power
  - after turning on power flush the boot loader right away
#+BEGIN_SRC shell
   make NUM=2
#+END_SRC
  
* <2016-12-11 Sun> - Eigenbau 2 pingable
    - We're using the deRFmega128-22M10 with a Atmega128rfa1 so the default *TARGET=osd-merkur-128* is ok for us
    - flash new Contiki (as of 0812b89) since f87c6f crashes early, likely due to us using the [bonsai bootloader](https://github.com/osdomotics/osd-hardware/tree/master/bootloaders/atmega-bonsai) now
    - set the channel back to 26 as in f87c6f, defaults to 25 otherwise
    - slip6 see https://honk.sigxcpu.org/piki/hw/merkur-board/
    - ping

* <2017-01-15 Sun> - Eigenbau 2 with correct mac
  - Added clean before each flash so we get a fresh firmware built with the right mac
  - Reflashed first stage bootloader

* Further TODOs
  - [X] flash bootloader again with correct MAC, so far we flashed the default in the bonsai code
  - [X] add antenna
  - [X] add temp sensor
  - [X] flash temp firmware
