<div>== Fixing Bluetooth ==<br />
Some users have noticed instability with their wireless driver. Upgrading the driver to the version provided by LibreELEC may help! To do this, download the BCM4345C0.hcd, brcmfmac43455-sdio.bin, and brcmfmac43455-sdio.txt from the [https://github.com/LibreELEC/brcmfmac_sdio-firmware/tree/master libreELEC repositories] and place them in the same location as your previous firmware (`/lib/firmware/brmc/`). Then rename brcmfmac43455-sdio.{txt,bin} as `brcmfmac43455-sdio.pine64,pinenote-v1.2.{txt,bin}`. If this doesn't help, ask about it in the matrix chat!<br />

=== Preliminary fix for stuttering bluetooth audio ===<br />
Following a fix used for the Quartz Model A (which uses the same SoC as the Pinenote), we can modify the device tree prior to building the kernel to try to mitigate poor Bluetooth audio streaming. (reference: see https://lore.kernel.org/linux-arm-kernel/20220926055435.31284-1-leo@nabam.net/T/)<br />
<br />
'''Steps:'''<br />
<br />
* Open <code>arch/arm64/boot/dts/rockchip/rk3566-pinenote.dtsi</code><br />
* Go to line 939, "bluetooth", under the "uart1" section<br />
* Edit the two lines that read "device-wake-gpios" and "host-wake-gpios"; you want them to read "device-wakeup-gpios" and "host-wakeup-gpios" respectively<br />
* Add the following line to the end of the bluetooth section (under the vddio-supply line in my .dtsi): "max-speed = <3000000>;" <br />
* Count your zeros, don't forget your punctuation..<br />
<br />
'''Caveats:'''<br />
<br />
This will improve BT audio quality at least when using the AAC codec. In my experience, the quality is more than acceptable, but there are still issues apparent: occasional isolated stutters even on AAC; prohibitively frequent stutters on SBC-XQ remain. Fully resolving BT audio issues might require further changes similar to the one described above, or may alternatively be a matter of audio software settings (e. g., process priority, audio server buffer settings). Investigation ongoing.<br />

== libinput Palm Detection ==<br />
See https://gitlab.com/hrdl/pinenote-shared/-/blob/main/etc/libinput/local-overrides.quirks.<br />
<br />
== libinput Touch Arbitration ==<br />
Prerequisites: <code>libinput>1.22.1</code> and setup touch arbitration via udev: https://gitlab.com/hrdl/pinenote-shared/-/blob/main/etc/udev/rules.d/81-libinput-pinenote.rules<br />
<br />
=== Issues and workarounds ===<br />
* No resolution reported by touchscreen driver. Workaround: patch <code>cyttsp5.c</code> and device tree: https://gitlab.com/hrdl/linux/-/commit/f1f9eb197d3bd88c9189ab9d8fba2d03d2e13960 or set device quirk <code>AttrSizeHint=210x157</code>.<br />
* Touch screen arbitration is independent of the screen's rotation. Workaround: use <code>AttrEventCode=-ABS_TILT_X</code> (on older version: <code>AttrEventCodeDisable=ABS_TILT_X</code>) in a libinput quirk matching <code>w9013 2D1F:0095 Stylus</code>. This makes touch arbitration independent of the pen's location.<br />
<br />
== Getting Waydroid to run ==<br />
<br />
* Open <code>/usr/share/u-boot-menu/conf.d/u-boot-pinenote.conf</code><br />
* Go to line U_BOOT_PARAMETERS<br />
* Add to end end of the list psi=1<br />
* run <code>u-boot-update</code><br />
* reboot<br />
<br />
'''Caveats:'''<br />
Networking in Waydroid does not work yet<br />
