[OP zero 2+ H5 - can't read the devices /dev/ttyS*]

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 !!

[Orange Pi lite -Boot problem after several days of working]

Hi,

I always have a boot problem with the OP lite after operating approximately for 2 weeks !!  

When the problem occurs, I got the following message while the system is booting :

Please check your kernel config and/or bootloader.

 

 

Even though, if I just connect the memory card to my computer and reconnect it to the OP lite again, everything seem to work fine!

[Access Point problem with Orange Pi Zero 2+ H3]

Ok thank you so much .

It is solved right now !! (I have just changed the ip address to static again   )

[Access Point problem with Orange Pi Zero 2+ H3]

Hi,

Thank you again for your response.

After typing the suggested command, I got the following error message:

libkmod: ERROR ../libkmod/libkmod-config.c:635 kmod_config_parse: /etc/modprobe.d/ap6212.conf line 1: ignoring bad line starting with 'option'

[Access Point problem with Orange Pi Zero 2+ H3]

Thank you for your quick response . Yeah sorry for not being precise enough in my previous post .

Actually, the board boots normally and the OS is updated and upgraded. This is the given URL after typing ‘armbianmonitor -u’:  http://sprunge.us/HYDX

Below you can find the files ‘hostapd.conf’ and ‘interfaces.conf’.

I also disabled the networkmanager services:

systemctl stop NetworkManager.services

systemctl disable NetworkManager.service

After typing the following command: sudo /usr/sbin/hostapd /etc/hostapd.conf       

I get:

Configuration file: /etc/hostapd.conf

nl80211: Could not re-add multicast membership for vendor events: -2 (No such file or directory)

Using interface wlan0 with hwaddr e0:76:d0:df:41:bc and ssid "ARMBIAN"

wlan0: interface state UNINITIALIZED->ENABLED

wlan0: AP-ENABLED

 

Even though it is written that the AP is enabled, I can’t see my hotspot on the list of wireless networks !!

hostapd.conf

interfaces.conf

[Access Point problem with Orange Pi Zero 2+ H3]

Hi,

It's been a while that I'm trying to activate the AP of the OP Zero 2+ but in vain. I already succeded activating it on the OP Light using hostapd.conf and interfaces.conf, but when I tried the exact same configuration on OP Zero 2+ the AP didn't work. 

I tried a lot of solutions found in the internet, but none of them seem to work.

Please any help would appreciated !
