Bug ID: 1195297 Summary: fbtft spi screens no longer functions properly. Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: aarch64 OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: simonf.lees@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: ---

Connected to the raspberry pi on my Robot I have a small 3.2" display [1] (or a clone / older version) it connects via SPI on the raspberry pi's GPIO header. In the past i've had it working with the overlay at [2] and the fbtft driver.

This kinda setup is pretty common in the embedded / hobbyist world, I don't use a desktop or anything just simple status apps using the framebuffer directly on the other hand it wouldn't be the end of the world if I moved to Qt.

Today I finally got a chance to update and as of now I no longer have an /dev/fb1 (/dev/fb0 is hdmi) is that expected with my current setup? I had other issues with the update and had to grab a fresh image and re add my overlay and raspbery pi config so there is also a chance I missed something setting it up again. I've put some dmesg output from the older system the new system shows nothing and below that is an fbi command I use for testing.

Log from previously working system: [ 59.468595] fbtft: module is from the staging directory, the quality is unknown, you have been warned.
