Cc2530 zigbee gpio 14 & 15

I have connected a custom zigbee board on gpio 14 & 15 and was wondering which zigbee component to use.
After making the changes to the Raspberry PI 3, so I could use gpio 14 & 15 ( normally used for console and bluetooth )
I can’t get it to work.
I don’t say this is a Home assistant problem, though i’m unable to communicate with the board. Not sure where the problem is.
I tried:

zha:
    usb_path: /dev/ttyS0
    database_path: /home/homeassistant/.homeassistant/zigbee.db

this halts on starting the zha component.
When I try to configure it like.

zigbee:
device: /dev/ttyS0
baud: 9600

I start’s up but i’m not sure howto pair a device like Ikea Tradfri or other.
Any advise / tips, tricks are welcome.
