Hello,
I want to enable the uart 1 and 4 on a beaglebone.
I can see so far:
The gpio's for the PINS are well up and configured.
How do I configure the P_9 pins as UART ? On Linux I can use
Is there in freeBSD a similar command.
Where I can check which dtbos are loaded. the boot/ folder has so many files.
Which one is the good one to add new dtbos and where to put the compiled dts files.
Thank you.

Code:
grep -E '^(sio|uart)[0-9]' < /var/run/dmesg.boot
uart0: <TI UART (16550 compatible)> mem 0-0xfff irq 13 on ti_sysc2
uart0: console (115384,n,8,1)

root@generic:/home/freebsd #
The gpio's for the PINS are well up and configured.
Code:
P_9 11 and 13
pin 30: 1 gpio_30<IN,PU>, caps:<IN,OUT,PU,PD,UNKNOWN,UNKNOWN,UNKNOWN,UNKNOWN,UNKNOWN>
pin 31: 1 gpio_31<IN,PU>, caps:<IN,OUT,PU,PD,UNKNOWN,UNKNOWN,UNKNOWN,UNKNOWN,UNKNOWN>
P_9 15 and 14
pin 24: 0 gpio_24<>, caps:<IN,OUT,PU,PD,UNKNOWN,UNKNOWN,UNKNOWN,UNKNOWN,UNKNOWN>
pin 25: 0 gpio_25<>, caps:<IN,OUT,PU,PD,UNKNOWN,UNKNOWN,UNKNOWN,UNKNOWN,UNKNOWN>

Code:
config-pin p9.11 uart
config-pin p9.13 uart
