The device has been tested to work without any known issues or limitations, please file a bug in the armbian tracker if you encounter any.

DRM_IOCTL_MODE_CREATE_DUMB failed

Linux 6.1.X introduced regression in mesa causing DRM_IOCTL_MODE_CREATE_DUMB failed: Cannot allocate memory resulting in various rendering issues and even failure to perform first installation, see mesa/mesa#8198 for tracking.

The issue has been addressed in mesa/mesa/commit/c426e5677f36c3b0b8e8ea199ed4f2c7fad06d47
and evidently shipped in Linux 6.2.X.

Merge request armbian/os#45 was submitted to use edge kernel to workaround this issue, may introduce issues with armbian-firmware causing display to not work as cause it not yet fully understood, if that happens utilize the debuging cable and invoke:

$ picocom /dev/ttyUSB0 -b BAUM # Opens serial console on the laptop

The BAUM is by default 115200 as specified in https://github.com/armbian/build/blob/main/config/boards/olimex-teres-a64.conf or your SERIALCON, if you specified it in your installation, note that BAUM beyond 115200 is not recommended.

To install armbian-config (if it’s not installed already) and update the firmware, the display should then work again after reboot.

If you encounter this issue, then please inform @kreyren about it.

Pine H64

  • PCIe port is not supported: Allwinner H6 has a quirky PCIe controller that doesn’t map the PCIe address space properly to CPU, and accessing the PCIe config space, IO space or memory space will need to be wrapped. As Linux doesn’t wrap PCIe memory space access, it’s not possible to do a proper PCIe controller driver for H6. The BSP kernel modifies the driver to wrap the access, so it’s also not generic, and only devices with modified driver will work. Armbian does not support BSP based kernels. You can find more information here and here.
  • USB3 sometimes doesn’t detect high-speed devices properly
