Hello Community, Like the topic says, i have a question how to upgrade the Tinker OS on a running machine. of course I tried the usual sudo apt…. console commands. But how to Upgrade a full release from 2.0.4 to 2.1.6 without flashing it completely new? Thanks for a hint in advance

I have a question referring to this, from the wiki on github For Tinker Board 2 / Tinker Board 2S The FAN connector offers 500mA maximum by hardware design. It provides be controlled High/Low speed by software and kindly find the control method below: High speed setting on FAN_SPD_CTRL sudo -i echo "154" > /sys/class/gpio/export echo "out" > /sys/class/gpio/gpio154/direction echo "1" > /sys/class/gpio/gpio154/value Low speed setting on FAN_SPD_CTRL echo "0" > /sys/class/gpio/gpio154/value _____________________________________________________ This works flawless, I can set 2 speeds. „Fast“ and I’d call it „medium“. i would appreciate a „slow“ and „silent“ setting! The two that are already available are to fast and loud. How can I get this feature? Can someone Programm it? (I tried to plug my fan in the 3volt and it runs super silent but I am afraid to damage something related to the max 50ma output . The fan is at 48ma at 5V in the documentation) Cheers Andreas
