Is that all you have done? No configuration changes? And does it start out working and then turn white, or is it always white? Please be more specific.
When you have some more details, I suggest you go to the forums and post there. If you later determine that it is a firmware problem then come back here.
I don't think the firmware include drivers for the PiTFT's. notro's drivers are in Linux staging though, so maybe they will be included soon.
They are already in raspberrypi/linux and released firmware.
i have updated the firmware Kernel version: Linux 3.18.8-v7+ armv7l But the screen is white
Ping @notro.
That display is not supported by vanilla FBTFT. You have to use Adafruit's kernel. Adafruit's FBTFT fork: https://github.com/adafruit/adafruit-rpi-fbtft
Will this make it work: https://github.com/raspberrypi/linux/pull/858 Does Adafruit's fork have working touchscreen?
858 is for the PiTFT 2.8" display. Supported by FBTFT and uses in-tree stmpe touch controller support. The PiTFT 3.5" uses a patched FBTFT in addition to an out-of-tree touch controller driver. @ladyada do you care to clarify?
oof its a long story :) i do have a set of patches for supporting the 3.5" TFT (HX8357) which i neglected to submit to notro, but maybe will submit to mainline once that's settled.
The Pi 2 has some IRQ handling differences that make the STMPE touch incompatible, @popcornmix if its OK i might email eben & team with my findings this week, or I can message you directly somehow?
All this to say.. @HunorR If you have a Pi 1, follow these instructions to install the 3.12 kernel with 3.5" support. https://learn.adafruit.com/adafruit-pitft-3-dot-5-touch-screen-for-raspberry-pi/easy-install
@HunorR , If you have a Pi 2 please hold on, we're packaging up new deb's for 3.18 support at this very moment and will post on the adafruit blog the moment we have good and tested files :) I estimate we'll have something by friday for release (unless something unexpected happens)
@ladyada yes i have a Pi 2, ok i check back next week i hope it can be fixed. Thx for the update!
@ladyada , I have updated the raspberry to Kernel version: Linux 3.18.9 , but steel im getting white screen on the screen. I am using a PiTFT 3.5" Res Touch
@HunorR - there are still a few things we need to fix, so you may want to wait until later today, but have a look at the README for Adafruit-PiTFT-Helper. We have a packaged kernel build and config script which will probably get you what you need.
Is this supposed to be working by now? I have a Pi 2 and the 3.5" screen, and the screen is just white.
Tried with a new Rasbian image and adafruit-pitft-helper, but no change.
The FAQ for the 3.5 talks about /etc/modprobe.d/adafruit.conf, but it does not exist on my device. There is no mention of fbtft_device in the startup logs, and /dev/fb1 is not created.
Edit: Manually running modprobe fbtft_device name=adafruitrt35
gives Invalid argument, which suggests that adafruit-pitft-helper has not installed drivers correctly, right?
It works when you use the prebuilt image, but the adafruit-pitft-helper does not.
(Sorry for bumping and it probably not being the right place to ask, but the issue wasn't closed and I couldn't find anything about it elsewhere.)
Yah its been working quite a while. Try out the easy image. https://learn.adafruit.com/adafruit-pitft-3-dot-5-touch-screen-for-raspberry-pi/easy-install if you can't figure it out, post in the adafruit forums, the raspi foundation doesnt provide support for the PiTFT :)
@ladyada can this be closed? It looks like it is an Adafruit issue or am I mistaken?
yah go for it, since the OP never replied, they probably got it working!
well we just put it aside for a while
I have connected a PiTFT 3.5" Res Touch screen but it becomes white and it doesn't do anything.
