orangepi one and ili9340

[arhi]

I started first with orangepi pc2 (H5)  but now trying the same thing on orangepi one (h3) -

 

trying to make ili9340 module work

 

it works flawlesly on rpi with raspbian so the hw module works (and the fb_ili9340 module in kernel talks to it properly)

debug info I pulled from rpi

on the armbian, no matter what I do I can't get the fb_ili9340 to create /dev/fb1
the module loads ok and displays no errors but no /dev/fb1

 

dmesg shows

 

...

I modified armbianEnv

tried without spi-add-cs1 too, without max_freq...

 

it's based on stretch and mainline ... I can try old kernel too if that makes sense..

Bringing SPIDEV isn't related to framebuffer. It can only provide you access to the display from userspace program such python script.

To make it attached as framebuffer, you need much more complex DT overlays such the ones found where : https://github.com/notro/fbtft/blob/master/dts

I'm not smart enough to figure out how to make the DTS from scratch myself... I tried to modify the DTS that works on RPI to work on OPI but had zero success... then I finally got this to work in a way I see the /dev/fb1 on pc2 by adding "overlays=spi-spidev spi-add-cs1" to Env, and by loding fbtft_device with additional parameters..
 

modprobe fbtft_device name=pitft gpios=reset:24,dc:25

 

it all then start to "behave" like it's working, new framebuffer device is created, ili module is loaded etc etc ... but screen don't show no data .. at this point I suspect the gpios part is problematic as those gpio24 and gpio25 are rpi numbering, the scheme is different on opi so I tried reset:5,dc:6 but nothing happened .. so now I'm searching for other solution

also having weird issue with compiling kernel, stmpe_ts module is nowhere to be found in the kernel configuration, I added it manually to .config and loaded it and then it shown but, weird, also the ili_9340 and ili9341 modules, they are built but I don't see them neither in the configuration of the kernel.. something fishy is going on

I know, seen all those in the saved config ... "but" when I'm going trough the menu of armbian shown config (I assume the script calls make menuconfig) in the menus I don't see the option to not build ili drivers (they are always on, I have no issues with that but it's just weird) and the config option for the stmpe_ts never shows in the menus ?!?!? now for the stmpe if I add a line in config enabling it and load that config I see the stmpe in the menus then, but not before that, weird...

Pretty normal, it is a dependency ... After enabling it, you need to compile a new kernel ...
