This stick supports dual boot. 

`k0` and `r0` respectively contain kernel and firmware of the first image, while `k1` and `r1` contain kernel and firmware of the second one.

## Serial

The stick has a TTL 3.3v UART console (configured as 115200 8-N-1) that can be accessed from the top surface: it's near the SFP header. TX, RX and ground pads need to be connected to a USB2TTL adapter supporting 3V3 logic.

This will force the stick to use your own settings from the XML file, but this is a hack and causes sigsegv of `/bin/checkomci`."
