The WCNSS firmware from DB410c is also useful for other devices
that can run unsigned firmware (e.g. bq-paella) because it is newer
and reportedly has some WiFi/BT coexistence problems fixed.
To allow easy switching betwen the original firmware from the manufacturer
(firmware-bq-picmt-wcnss) and the newer firmware (firmware-qcom-db410c-wcnss)
we make both packages provide a virtual "firmware-qcom-msm8916-wcnss"
package. The newer version from firmware-qcom-db410c gets a higher
provider_priority so it is installed by default.
However, the user can choose to do "apk add firmware-bq-picmt-wcnss"
to get the original firmware from the manufacturer instead.
The DB410c is a SBC with APQ8016 SoC. It runs on mainline without
any patches. This port makes use of the existing linux-postmarketos-qcom-msm8916
kernel package that is used for other mainline MSM8916 devices.
Tested functionality:
- USB Network, USB Host (e.g. an USB keyboard)
- Flashing (Fastboot)
- Display (HDMI)
- WiFi/BT
- GPU
- Audio (HDMI)
- FDE
Not tested:
- GPS
Note: The firmware package is called firmware-qcom-db410c (instead of arrow)
because the firmware is provided directly by Qualcomm, not Arrow.
