Manual build
You can build things for yourself by following our Manual build howto and by choosing from the configurations available below.
U-Boot
Mainline U-Boot
Use the "q8_a33_tablet_1024x600_defconfig" build target.
Linux Kernel
Mainline kernel
Use the "sun8i-a33-q8-tablet.dtb" device-tree binary.
Wi-Fi kernel module: https://github.com/Icenowy/rtl8723cs/tree/new-driver-by-megous
Tested with kernel 5.15.0-rc1-00014-g316346243be6
How to compile:
make -C [KERNEL_PATH] ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- M="$(pwd)" modules \ CONFIG_RTL8723CS=m
For turn off power save execute:
echo 'options 8723cs rtw_power_mgnt=0 rtw_enusbss=0' | sudo tee /etc/modprobe.d/8723cs.conf
CONFIG_IPV6 must be OFF in kernel otherwise Wi-Fi driver will crash!
FEL mode
The something button triggers FEL mode.
Adding a serial port (voids warranty)
There a two pads right of A33 chip. They are actually B0 and B1 pads of SOC.
Device disassembly
See the Q8 tablet format disassembly page.
Locating the UART
Describe how to find the RX,TX,GND signals here, and mention the UART howto.
