odroid cloudshell2 hktft9340 kernel module missing

[ELIAST]

Hi.

I recently installed an

Armbian 25.8.1 noble
to an ODROID XU4 with CLOUDSHELL2.

All is wonderful, except one thing. I can't make the small TFT work. I enabled the cs2 option in boot.ini, but did not solve the issue. Then it turned out the module loader in modproebe.d lokks as follows:

options fbtft_device name=hktft9340 busnum=1 rotate=270 speed=35000000 force32b=1 bgr=1

but actually there is no such module (only hktft32 or hktft35, or ili9340 - none of these worked):

How should it be possible getting this hktft9340 module into the kernel?

 

Thank you!

All. After some more research I could dig further, but still no picture on the tft screen.

 

It seemes, the same probelm already popped up elsewhere:

https://github.com/notro/fbtft/issues/577

 

by using some ideas there, I could achieve the follwoing:

[   11.299717] fbtft: module is from the staging directory, the quality is unknown, you have been warned.
[   11.305551] fb_hktft32 spi1.0: fbtft_property_value: bpp = 16
[   11.305563] fb_hktft32 spi1.0: fbtft_property_value: debug = 0
[   11.305574] fb_hktft32 spi1.0: fbtft_property_value: rotate = 270
[   11.305584] fb_hktft32 spi1.0: fbtft_property_value: fps = 20
[    4.988032] /soc/spi@12d30000/hktft_cs_ogst@0: Fixed dependency cycle(s) with /soc/spi@12d30000/hktft_cs_ogst@0/hktft_cs_ogst_pins
[   11.305404] SPI driver fb_hktft32 has no spi_device_id for odroid,hktft32
[   11.855462] graphics fb0: fb_hktft32 frame buffer, 320x240, 150 KiB video memory, 4 KiB buffer memory, fps=20, spi1.0 at 40 MHz
 

Which  seemes the display is visible by the system now.

fbset

mode "320x240"
    geometry 320 240 320 240 16
    timings 0 0 0 0 0 0 0
    nonstd 1
    rgba 5/11,6/5,5/0,0/0
endmode
 

following this route:

https://unix.stackexchange.com/questions/20458/how-to-use-dev-fb0-as-a-console-from-userspace-or-output-text-to-it

To use the framebuffer as console you need the fbdev module. 

Ok, let's see this.

config-6.6.113-current-odroidxu4 has reference saying

ONFIG_FRAMEBUFFER_CONSOLE=y

so the above referenced fbdev should already be here.

 

The lcd scripts coming with cloudhell al trying to send text to /dev/tty1 as the output console. So I assume, I should have something similar:

dmesg|grep tty
[    0.000000] Kernel command line: splash=verbose console=ttySAC2,115200n8 console=tty1 consoleblank=0 loglevel=1 root=UUID=4cac61c9-e109-4524-9fd2-c9859f87842c rootfstype=ext4 rootwait rw drm_kms_helper.edid_firmware=edid/1024x768.bin smsc95xx.macaddr=00:1e:06:61:7a:55 governor=ondemand hdmi_tx_amp_lvl=31 hdmi_tx_lvl_ch0=3 hdmi_tx_lvl_ch1=3 hdmi_tx_lvl_ch2=3 hdmi_tx_emp_lvl=6 hdmi_clk_amp_lvl=31 hdmi_tx_res=0 HPD=false vout=dvi usb-storage.quirks=0x2537:0x1066:u,0x2537:0x1068:u

[    2.123447] 12c20000.serial: ttySAC2 at MMIO 0x12c20000 (irq = 125, base_baud = 0) is a S3C6400/10

[    9.716917] systemd[1]: Expecting device dev-ttySAC2.device - /dev/ttySAC2...
 

ttySAC is the UART what I'm using at the moment. tty1 however is my main "screen", on the HDMI.

 

So the question is, how should I able to tell the system to open an other tty console with  fbdev for the LCD screen?
