arhi Posted January 5, 2019 Share Posted January 5, 2019 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 pi@octopi:~ $ uname -a Linux octopi 4.14.79-v7+ #1159 SMP Sun Nov 4 17:50:20 GMT 2018 armv7l GNU/Linux root@octopi:~# lsmod Module Size Used by xt_tcpudp 16384 1 iptable_mangle 16384 1 xt_DSCP 16384 1 bnep 20480 2 hci_uart 36864 1 btbcm 16384 1 hci_uart serdev 20480 1 hci_uart bluetooth 368640 24 hci_uart,bnep,btbcm ecdh_generic 28672 1 bluetooth fb_ili9340 16384 0 fbtft 45056 1 fb_ili9340 syscopyarea 16384 1 fbtft sysfillrect 16384 1 fbtft sysimgblt 16384 1 fbtft fb_sys_fops 16384 1 fbtft stmpe_ts 16384 0 joydev 20480 0 evdev 24576 4 brcmfmac 307200 0 brcmutil 16384 1 brcmfmac cfg80211 573440 1 brcmfmac rfkill 28672 6 bluetooth,cfg80211 snd_bcm2835 32768 0 gpio_backlight 16384 0 i2c_bcm2835 16384 0 snd_soc_bcm2835_i2s 16384 0 snd_soc_core 188416 1 snd_soc_bcm2835_i2s snd_compress 20480 1 snd_soc_core snd_pcm_dmaengine 16384 1 snd_soc_core snd_pcm 98304 4 snd_pcm_dmaengine,snd_soc_bcm2835_i2s,snd_bcm2835,snd_soc_core spi_bcm2835 16384 0 snd_timer 32768 1 snd_pcm snd 69632 5 snd_compress,snd_timer,snd_bcm2835,snd_soc_core,snd_pcm uio_pdrv_genirq 16384 0 fixed 16384 0 uio 20480 1 uio_pdrv_genirq ip_tables 24576 1 iptable_mangle x_tables 32768 4 iptable_mangle,ip_tables,xt_tcpudp,xt_DSCP ipv6 425984 45 root@octopi:~# root@octopi:/dev/input# ls -la total 0 drwxr-xr-x 4 root root 220 Jan 3 02:59 . drwxr-xr-x 15 root root 3420 Jan 3 02:59 .. drwxr-xr-x 2 root root 120 Jan 3 02:59 by-id drwxr-xr-x 2 root root 140 Jan 3 02:59 by-path crw-rw---- 1 root input 13, 64 Jan 3 02:59 event0 crw-rw---- 1 root input 13, 65 Jan 3 02:59 event1 crw-rw---- 1 root input 13, 66 Jan 3 02:59 event2 crw-rw---- 1 root input 13, 67 Jan 3 02:59 event3 crw-rw---- 1 root input 13, 63 Jan 3 02:59 mice crw-rw---- 1 root input 13, 32 Jan 3 02:59 mouse0 crw-rw---- 1 root input 13, 33 Jan 3 02:59 mouse1 root@octopi:/dev/input# root@octopi:/dev/input# udevadm info -q all /dev/input/event3 P: /devices/platform/soc/3f204000.spi/spi_master/spi0/spi0.1/stmpe-ts/input/input3/event3 N: input/event3 S: input/by-path/platform-3f204000.spi-platform-stmpe-ts-event E: DEVLINKS=/dev/input/by-path/platform-3f204000.spi-platform-stmpe-ts-event E: DEVNAME=/dev/input/event3 E: DEVPATH=/devices/platform/soc/3f204000.spi/spi_master/spi0/spi0.1/stmpe-ts/input/input3/event3 E: ID_INPUT=1 E: ID_INPUT_TOUCHSCREEN=1 E: ID_PATH=platform-3f204000.spi-platform-stmpe-ts E: ID_PATH_TAG=platform-3f204000_spi-platform-stmpe-ts E: MAJOR=13 E: MINOR=67 E: SUBSYSTEM=input E: USEC_INITIALIZED=5285899 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 ...

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 Link to comment Share on other sites More sharing options...

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 Link to comment Share on other sites More sharing options...
arhi Posted January 7, 2019 Author Share Posted January 7, 2019 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 Link to comment Share on other sites More sharing options...

"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 ... https://docs.armbian.com/Developer-Guide_Build-Preparation/ Link to comment Share on other sites More sharing options...
