  2. ... and its dead again, i attached some additional data.
  3. Now i updated to Linux orangepizero 5.4.8-sunxi and removed xradio_wlan cfg80211 mac80211 modules
  4. Hello, I have been struggling for some time with random freezes. I am running application with i2c0 Fram and UART1 for transferring/receiving data based on MAX3232. The freezes cause no response from Orange PI (debug UART too), only unplug power helps. I read that it may be a problem with powering but i tried many USB power adapters 2A, 3A and ATX power (28A) connected to GND and 5v, nothing helps. I have lowered cpu max frequency to 816Mhz and still the same. All necessary data uploaded via armbianmonitor.
