Hi,

I have a problem while taping the following command : 

root@orangepizeroplus2:~# cat /dev/ttyS2
cat: /dev/ttyS2: Input/output error
root@orangepizeroplus2:~# cat /dev/ttyS1
cat: /dev/ttyS1: Input/output error
root@orangepizeroplus2:~# cat /dev/ttyS3
cat: /dev/ttyS3: Input/output error
root@orangepizeroplus2:~# cat /dev/ttyS0
^C
root@orangepizeroplus2:~#

Is there a way to activate those devices?

(I know that we can enable them using "script.fex" file  with OP H3 but I don't know how to do it with mainline kernel H5)

 

Please check the boot logs of the board here :

Please any help would be appreciated !!
