Use debug serial ttyFIQ0 for Zigbee/Razbee board

#1

Hi
I want to use a Rasbee zigbee shield on a Rockpi. https://phoscon.de/en/raspbee
The proble is that the system does not boot with the board attached. So I removed the console part from /boot/extlinux/extlinux.conf
but that’s still not enough?!

You need to check the hardware connection first. I don’t find the schematic for the module. By default the serial console is disabled in the main dtb and enabled in the hwconfig file. You should comment the console-on-ttyS2 and console-on-ttyS4.

Hi Jack,
sorry, i didn’t get it:
the board schematic fits to the rockpi since it is the same as the raspberry. And its working on the Raspberry. gpio connecor 1-12
I’ve found al lot of dtb files in /boot/dtbs/4.4.154-59-rockchip-g5e70f14/rockchip# but i don’t know what to do with
The board is using DEBUG_TXD and DEBUG_RXD which is in my opinion ttyFIQ0
I also couldn’t manage to turn on i2c
Ist so easy with raspi-config and such a pain on the rockpi
