  1. i am also experienced multiple system freeze event (when it happen all HDD and system LED are all ON on the front penal), the kernel is 6.6.22-current-rockchip64. strange enough i found the syslog in /var/log is empty.
  2. thanks! is there anywhere i can download current release other than the minimal? or only minimal is avaliable for current release
  3. sound great! does the current release 6.6.21 support OMV 7 install via armbian-config? by the way, i am still struggling to find the other current images instead of current minimal shown in https://www.armbian.com/helios64/#. can anyone help? thanks a lot!
  4. thanks! the default now set to the USB DAC now, but i found Mopidy not play to it...... trying to figure out why .... by the way, can i define card number of the USB DAC? as it will become 1 when plugged before boot, and 2 when it is plugged after the bootup. thanks! Joseph

  6. Hi, i have a live system running (Armbian on Orange Pi PC2). i found the Serial OTG on the microUSB is not work. and i didn't modified the image in the SD as described above before first boot. so now i only need to create the symbolic link in /lib/systemd/system as shown above? i checked there is nothing in my /etc/modules and no ttyGS0 in my etc/securetty and no serial-getty@.service in /lib/systemd/system any help here? thanks! Joseph

  9. hello i just install the latest armbian on orange pi pc2 board, the kernal is already 4.14 therefore the OTG function should be there. root@orangepipc2:~# dmesg |grep musb [ 1.323924] musb-hdrc musb-hdrc.1.auto: MUSB HDRC host driver [ 1.323939] musb-hdrc musb-hdrc.1.auto: new USB bus registered, assigned bus number 9 [ 1.324416] usb usb9: Manufacturer: Linux 4.14.78-sunxi64 musb-hcd [ 1.324421] usb usb9: SerialNumber: musb-hdrc.1.auto however, i cannot enable the usb serial over OTG. anyone can show me how to do it? i tried it on debian and windows but both has nothing when i connect to the OTG port. thanks very much!
