Dear Genode team,
I am Kimberly.

I modified and added some apps on demo.run
The genode version is https://github.com/tomga/genode/tree/rpi3bplus_19.02
I tried this commands : 
$ ./tool/create_builddir rpi3bplus   
$ make run/demo KERNEL=hw
This case successfully run on Rpi3 B+  
But I couldn't see the runtime log like as on x86_64 :
----------------------------------------------------------------------------------
...
[init -> drivers] Error: Could not open ROM session for "config"
[init -> drivers] Error: Uncaught exception of type 'Genode::Rom_connection::Rom_connection_failed'
[init -> drivers] Warning: abort called - thread: ep
[init] child "drivers" exited with exit value 1
[init -> acpi_drv] Found MADT
...
-----------------------------------------------------------------------------------
Like the above example, sometimes I want to debug errors on Rpi.
Can I see the runtime log on Rpi3 B+ ?
If it can, how to set on putty ? (p.s. I used USB to TTL Serial Cable)
In putty configuration :
serial line : /dev/ttyUSB0
speed : 115200
I also tried speed : 9600
But I still couldn't see runtime log. 

Maybe I have to refer to gpio_signal.run and then modify demo.run ?

p.s. If I used raspbian-stretch-lite.img (raspberrypi.com provide it), I can see runtime log.

Thanks a lot ! 😊
