Known Issues

  • When accessing the audio device (such as via hwtest), the device freezes. After reboot you may be prompted with a "Collecting Logs" screen with an Amazon logo, indicating some sort of firmware level log collector.
  • CPU1,2,3 continuously enable and disable themselves, with logs such as:
[  378.053320] -(3)[0:swapper/3]CPU3: Booted secondary processor
[  378.053334] -(3)[0:swapper/3][name:cpuinfo&]Detected VIPT I-cache on CPU3
[  378.053385] -(3)[0:swapper/3][name:topology&]CPU3: update cpu_capacity 1024
[  378.122632]  (0)[1829:kworker/0:2][name:mtk_wcn_stub_alps&][cmb_stub] thermal_ctrl_cb null
[  378.342631] -(0)[1600:kwin_wayland][name:sched_monitor&][BURST IRQ DURATION WARN] IRQ[ 51:musb-hdrc.0.auto] +1237 ( dur 30000 us , avg 24 us)

[  380.053771]  (1)[71:hps_main][name:smp&]CPU3: shutdown
  • Although the kernel can detect plugged in USB keyboard, nor X neither wayland can use the keyboard. evtest works tho. USB drives also mounts correctly..

How to enter flash mode


Alternatively, you can flash just the boot_x partition and then flash the rest of the system on an external sdcard:

  • pmbootstrap install --sdcard=/dev/...: This will install the rootfs on a SD card mounted on your computer.
  • fastboot flash boot_x boot.img-amazon-douglas: This will flash the initramfs onto the device.
  • Then remove the sd card from your computer and insert it into the device. Then reboot it.
  • Future updates to the rootfs does not require additional fastboot operations.
