broody13 Posted June 21, 2019 Posted June 21, 2019 (edited) Hello, I have an Orange Pi 3 I bought this display https://www.amazon.com/gp/product/B07P7TLLRN/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1. It looks like it uses the ili9486l driver but I cant find any instructions that apply for this set up. I tried to follow this guide: https://kaspars.net/blog/spi-display-orange-pi-zero and after using: modprobe fbtft_device custom name=fb_ili9340 gpios=dc:3,reset:0 speed=16000000 busnum=1 rotate=90 dmessage showed: [ 408.747027] fbtft: module is from the staging directory, the quality is unknown, you have been warned. [ 408.750915] fbtft: unknown parameter 'custom' ignored [ 408.750925] fbtft: unknown parameter 'name' ignored [ 408.750932] fbtft: unknown parameter 'gpios' ignored [ 408.750938] fbtft: unknown parameter 'speed' ignored [ 408.750944] fbtft: unknown parameter 'busnum' ignored [ 408.750950] fbtft: unknown parameter 'rotate' ignored now the problem is that my instalation (Debian Stretch with Armbian Linux 5.1.7-sunxi64) doesn't show any framebuffer at least named fb under /dev. I have thinker around with Linux but only superficially so I really don't understand the ins and outs. Can someone point me to the right direction? Edited June 21, 2019 by broody13
broody13 Posted June 23, 2019 Author Posted June 23, 2019 Ok, It looks that fb doesn't show up unless the HDMI cable is plugged in. Plus the tutorial is from 2017 and it looks like Armbian moved to the new kernel and I suspect the drivers are not loaded on the kernel.
broody13 Posted June 24, 2019 Author Posted June 24, 2019 (edited) I apologize if bumping a thread is forbidden but I'm trying to document what I found. I found this thread where someone reported that it managed to enable a similar display but for some reason aptitude install linux-headers-next-sunxi is not working. (Of course the OrangePi3 build is being tested) on both Debian and Ubuntu failed. Under Debian top showed no processor activity, but after switching to Ubuntu it finally reached 100% cpu usage and after a while the command ended saying that it was unable to find a package named linux-headers-next-sunxi. Then I tried apt install linux-headers-next-sunxi not sure if apt and aptitude brings different results but this time the compilation process started but it got stuck a 67%.Then on the next attempt under Ubuntu I'm also getting E: Unable to locate package linux-headers-next-sunxi Maybe the package is being fixed. PD: I have been using a Lexar Professional 1000X 64GB MicroSDXC Uhs-II Card and also installed everything on the emmc Edited June 24, 2019 by broody13 grammar
