piTFT not working after Raspbian update

[evharten]

Just try'd the new .deb (beta) that gives instantly this failure.

Reverting back to raspberrypi-bootloader-adafruit-112613.deb.

[evharten]

raspberrypi-bootloader-adafruit-20140227-1.deb is the one causing the problems.

Thanks for the info. I'll pass that along to the development team.

If you have a newer .deb of the DMA driver let me know, ill be more then happy to test it!

I am testing here on raspbian and can confirm that with the DMA kernel module, GPIO is not working (and similar error messages during boot).

Once I installed the other *-112613.deb, the GPIOs started working and I was then able to switch the backlight on and off with the instructions in the tutorial.

No idea how this worked out, but I ran into very similar symptoms. Display seemed to work fine, touchscreen not recognized. This thread came up in searching for solutions. (I'm not linking those threads because that didn't work for me.)

I'd started by following the install guide for the resistive screen by mistake, and downloaded the (ostensibly preconfigured) Raspian version for that as referenced in the instructions. Found the capacitive screen instructions only later (https://learn.adafruit.com/adafruit-2-8 ... ive-touch/) only later, and worked through those. Display worked, no dice on the touchscreen.

Turned out I hadn't paid attention during the software install, and packages were missing that I overlooked because the console worked on the PiTFT. Look out for this, which normally be buried up top in the dpkg output and is a fatal error, shown as as a discreet dkg run here to illustrate.
