触摸屏上的Android Things黑屏3.2英寸

Question

我尝试在我的覆盆子中使用3.2英寸的触摸屏和android的东西，但是没有用!! 我经常搜索，但没有任何帮助我！ 这是我原来的config.txt：

kernel=u-boot-dtok.bin<br>
framebuffer_depth=16<br>
dtparam=i2c_arm=on<br>
dtoverlay=pwm-2chan-with-clk,pin=18,func=2,pin2=13,func2=4<br>
dtparam=spi=on<br>
dtparam=audio=on<br>
start_x=1<br>
Tell U-boot to always use the "serial0" interface for the console, which is<br>
set to whichever uart (uart0 or uart1) is set to the header pins. This doesn't<br>
interfere with the uart selected for Bluetooth.dtoverlay=chosen-serial0<br>
Enable skip-init on the UART interfaces, so U-Boot doesn't attempt to<br>
re-initialize them.dtoverlay=rpi-uart-skip-init<br>
Uncomment to disable serial port on headers, use GPIO14 and GPIO15<br>
as gpios and to allow the core_freq to change at runtime.enable_uart=1
core_freq=400<br>
