Today I've used fresh install Armbian_5.24_Orangepipc_Debian_jessie_default_3.4.113 and used my favorite WiFi dongle based on RTL8188CUS. But when tried to connect with nmtui, it halts the system and reboots. The WiFi is connected via a powered hub and the OPi PC has strong power supply too. It's not related to the power issue for sure. I've seen a lot of issues at the previous version, but guess that it was all solved before the version release.
EDIT: the driver issue still persists in this last version. When rebuild the driver, as described above, it works.
