  2. I confirm this bug. After updating orange pi zero to 4.14.15-sunxi it hangs occasionally.

  3. Hi. Is it possible to toggle usb power on Orange PI Zero? What does PL2 do?
  4. Is it possible to see it in future, or it's difficult and there are no plan for this task?
  5. USB audio is not usable with 4.x dev kernels on OPI Zero board. I don't see any errors, but audio goes with scratchs. Other usb devises works fine with 4.x dev. USB audio works well with 3.x stable kernel.
  6. Am I right, that there are no wifi support at uboot level for sunxi boards? And the only similar solution to use wifi at early level is to boot linux kernel with wifi support from SPI flash.
  7. Yes, under development, you're right. And yes, I can't boot stock Debian kernel. But I've just asked to include in config common modules, like usb drivers.
  8. armbianmonitor shows about 40C in idle for Nanopi Neo2 with stock radiator
  9. The kernel is poorly configured. Compare it with debian config-4.9.0-3-arm64 or even with config-3.4.113-sun8i. There are no CONFIG_USB_SERIAL_WWAN and many other drivers.
