This stick supports dual boot.
`k0` and `r0` respectively contain the kernel and firmware of the first image, while `k1` and `r1` respectively contain the kernel and the 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 a logic level of 3.3V.

customSwVersionAlert="This needs the `OMCI_OLT_MODE` value to be set to 3 and firmware 220530 or 220923 modded by @stich86 or if you don't want to replace firmware to change software version, set `OMCI_OLT_MODE` value to `21`. This will force to use your own settings from the XML file, but this is a hack and causes sigsegv of `/bin/checkomci`."
