All,

I have been adding split image to ble-nano.

What I found what that there is something happening with MK20 USB daughter 
board.  When I have the BLE module plugged into the daughter module, I am not 
able to use newtmgr commands with slinky.

However, when I unplug the module and wire power/gnd/tx/rx to the board (with a 
remote serial port), I am able to use newtmgr.

I am thinking there are two issues.


  1.  It seems like there are some serial characters coming out the board that 
is messing with newtmgr: "$$$10950203ADB91E7D92DF9FD5" is an example.
  2.  It would seem that when I make/break a serial connection to the MK20 via 
USB, it is resetting the nrf51 via the debug pins ( the device. Since newtmgr 
does this on every command, this may be causing it not to work.

Anyone have any knowledge about this?


Paul
