Hello, We are using Orange Pi Zero with Armbian Bionic with Linux 5.4.20-sunxi armv7l GNU/Linux we are facing a problem, our orange pi heats up some time during processing and then freezes. We can ping the devices, but ssh stops working and all the application don't respond We followed the suggestion in thread: https://forum.armbian.com/topic/7848-mysterious-freeze-and-overheat-of-orange-pi-zero/?ct=1587196371&_fromLogin=1 But output of "armbianmonitor -m" is as below Stop monitoring using [ctrl]-[c] Time CPU load %cpu %sys %usr %nice %io %irq CPU C.St. 11:19:37: 1008MHz 0.18 6% 1% 4% 0% 0% 0% 76.4°C 0/4 11:19:42: 1008MHz 0.17 3% 0% 2% 0% 0% 0% 75.1°C 0/4 11:19:47: 1008MHz 0.15 3% 1% 2% 0% 0% 0% 75.2°C 0/4 11:19:52: 1008MHz 0.14 4% 1% 2% 0% 0% 0% 74.8°C 0/4 11:19:57: 1008MHz 0.13 3% 0% 2% 0% 0% 0% 75.3°C 0/4 11:20:02: 480MHz 0.12 4% 1% 2% 0% 0% 0% 75.7°C 0/4 11:20:08: 1008MHz 0.11 14% 3% 10% 0% 0% 0% 74.8°C 0/4 11:20:13: 1008MHz 0.18 15% 1% 13% 0% 0% 0% 78.7°C 0/4 11:20:18: 1008MHz 0.41 13% 3% 9% 0% 0% 0% 79.1°C 0/4 11:20:23: 480MHz 0.37 21% 5% 15% 0% 0% 0% 76.8°C 0/4 11:20:28: 1008MHz 0.34 5% 1% 3% 0% 0% 0% 75.0°C 0/4 11:20:33: 1008MHz 0.32 4% 1% 3% 0% 0% 0% 74.5°C 0/4^C As you can see there is a flip in frequency for a very short time, not enough to cool the CPU Also the content of /sys/devices/system/cpu/cpufreq/ondemand/sampling_rate is 200000 So what could be the reason that the device freezes. Thanks,

How can we create a custom image of Armbian Bionic/Buster for Orange Pi Zero with our customized application/code in it. Please suggest process for the same.

Hello, I am using OrangePi Zero v1.1 board with 512MB DRAM and 8GB Class4 microSD card. I am trying to flash Ubuntu 18.04 LTS downloaded from Armbian site .. Everything goes well till the login point and then suddenly nothing moves. PS - USB adapter 5V, 1.6 Amp rating FTDI converter std. connected to UART of the board. Heatsink mounted on top of the IC. Please Help resolve the possible issue. Thanks !! Rajat Below is the boot up process as captured.
