subject:"\[beagleboard\] UARTS in kernel 4.4\: no \/dev\/ttO\* \?"

Re: [beagleboard] UARTS in kernel 4.4: no /dev/ttO* ?

2016-08-19 Thread Matt

Thanks for the info guys.  

Why is it that ttyS* are all listed when no BB-UART has been loaded into 
slots?

Work flow before was straight forward:
- Load a .dtbo
- Corresponding /ttyO* loaded.

Now I am unsure. When the BBB boots it shows all the /dev/ttyS*
Do I still have to load the corresponding .dtbo's?
Do I have to run the command 
setserial -g /dev/ttyS[0-5]

to bring up UARTS after every boot?

Re: [beagleboard] UARTS in kernel 4.4: no /dev/ttO* ?

2016-08-19 Thread Micka

ttyO* is for the omap driver. If i'm not wrong the kernel 4.4 use the
driver 8250.

You can switch back to the omap driver i' the config of the kernel.

 Don't think the ttyS's are it.  I know for sure in 3.18 you use the
 /ttyO2 or whatever number uart you enable.

 Can anyone confirm that in 4.4 the UARTS show as /ttyS*  ?

 Going to check my .dts.

Re: [beagleboard] UARTS in kernel 4.4: no /dev/ttO* ?

2016-08-18 Thread Matt

Don't think the ttyS's are it.  I know for sure in 3.18 you use the /ttyO2 
or whatever number uart you enable. 

Can anyone confirm that in 4.4 the UARTS show as /ttyS*  ?

Going to check my .dts.

[beagleboard] UARTS in kernel 4.4: no /dev/ttO* ?

2016-08-18 Thread Matt

Hi,

Working in kernel 4.4.16-bone-rt-r11 and am not seeing the corresponding 
entries in /dev/ for the enabled UARTS.

My custom DTS (BB-APA-01) enables a number of UARTS but I am not seeing the 
corresponding /dev/ttyO2, ttyO4, ttyO5, etc.  

Tried also loading the BB-UART2-00A0.dtbo from /lib/firmare/ as you can see 
below when I cat slots.
