Hello, I also tried to use the mainline(5.8.14) to drive my ILI9341 screen. I tried to write an overlay (see attachment) and added a similar description to the booted armbianEnv.txt. My current situation is: the screen is on but not displaying Any content. Can you check it for me? My cable connection method is as follows:
ILI9341 NanoPI_NEO Pin#
SCK --------------- 23
SCI/MOSI ----------- 19
SDO/MISO ---------- 21
CS -------------------- 24
DC/RS ----------------13 [GPIOA2 ]
RESET --------------- 11 [ GPIOA0 ]
VCC ------------------ 4(5V)
GND ------------------ 6
LED --------------------15 [GPIOA3]
This is my overlay source:
/dts-v1/; /plugin/; / { compatible = "allwinner,sun8i-h3"; fragment@0 { target = <&spi0>; __overlay__ { status = "okay"; }; }; fragment@1 { target = <&pio>; __overlay__ { opiz_display_pins: opiz_display_pins { pins = "PA0", "PA2", "PA3"; function = "gpio_out"; }; }; }; fragment@2 { target = <&spi0>; __overlay__ { /* needed to avoid dtc warning */ #address-cells = <1>; #size-cells = <0>; opizdisplay: opiz-display@0{ compatible = "ilitek,ili9341"; reg = <0>; /* Chip Select 0 */ pinctrl-names = "default"; pinctrl-0 = <&opiz_display_pins>; spi-max-frequency = <32000000>; rotate = <90>; bgr = <0>; fps = <33>; buswidth = <8>; reset-gpios = <&pio 0 0 1 >; /* PIN_11 GPIOA0 */ dc-gpios = <&pio 0 2 0>; /* PIN_13 GPIOA2 */ led-gpios=<&pio 0 3 0>; /* PIN_15 GPIOA3 */ debug=<4>; status="okay"; }; }; }; };This is my "armbianEnv.txt"

Do like this: so easy! on 5.8 kernel
1: exec: armbian-config --->system--->hardware, open irc
2: dmesg while found ir device, and build device file on /dev/lirc0
3: install lirc application
4: configure , move /etc/lirc/lircd.conf.d/devinput.lircd.conf to /etc/lirc/lircd.conf.d/devinput.lircd.conf-dist
5: use irrecord to build a remote contrel coding file, and put it to dir: /etc/lir/lircd.conf.d, do: systemctl restart lircd
6: irw try to use it.(If press key no output, do step 5 agaen. may be you need "ir-keytable -p xxx" set your protocol)
7: configure irexec , and exex it on daemon mode! OK!
I used lirc for "mpc command", and write a simplay script control music play!

After several days of study, I know that the new kernel version has cancelled the fbtft_device.ko method to drive fbtft, and changed it to the DT method. I also learned about the pinctrl subsystem, and tried to write an overlay by myself. After loading, the kernel has been found SPI device. The screen still doesn’t light up after the device is turned off. I don’t know the reason. I’m still looking for it. Can you help me?
dmesg output :
[ 12.229733] [drm] Initialized ili9341 1.0.0 20180514 for spi0.0 on minor 0 [ 12.706426] ili9341 spi0.0: fb0: ili9341drmfb frame buffer deviceThis is my overlay file, with DT fs check is OK!

Thanks again! There is a new knowledge point! Identified as not modifying dtb.
Now I am trying to add an ILI9341 screen to IT. Since the new kernel no longer supports fbtft_device.ko, it is modified to be defined by DT in dtb. I don't know yet. I am learning how to learn overlay to revise, just like this pcm5102a. If you don’t understand, try to add it yourself. If it is really unclear, I will post for help! enjoy working!

According to the method you introduced, the music played happily. thank you very much. Good good study, day day UP.

I2S seems to be no problem in the old version of armbian. So I am going to downgrade the version. The question now is how to compile the lower version? All scripts are defined as downloading the latest version.
too hard. The attachment is the current device tree definition. -
I want a digital music player base on NanoPi NEO, with device PCM5102A I2S sound card build.

I had build armbian 3 days ago, kernel ="5.8.13", with NanopiNEO, I want use a TFT screen, type is ILI9341, when I use "armbian-config" open spi_spidev, no /dev/spi* created, and screen does not work. here is config:
#
# cat /etc/modprobe.d/fbtft.conf options fbtft options fb_ili9341 name=fb_ili9341 gpios=rest:0,cs:67,dc:2,led:3 speed=48000000 fps=26 rotate=90 bgr=1 txbuflen=65536 debug=3here is armbian-hardware-monitor.log

Does somebody can help me, thinks very much!

I had try build a new kernel with tft screen , module ssd1322, find source , and build patch file, just like attach file <spender-ssd1322.patch>, and put it to patch : build/userpatches/kernel/sunxi-next, . then do "compile.sh", view patching.log, and compilation.log, compiler.log, no error! , directory build/cache/sources/linux-mainline/linux-4.19.y/drivers/staging/fbtft , no fb_ssd1322.o, .mod.c, .ko file output. build failed!
help me , how to do

thank you very much. In fact, my screen has indeed been driven. There is just no screen display. As you described, find a test program and it passed. Thanks again.
