Hi!
I want to learn about real time applications using the raspberry pi.
Found this guide on how to compile the rasbian kernel with rt patch. I also want to enable USB touchscreen support.
Tried cross compilation with the fedora version of arm-linux-gnu- and of course the raspi tools (arm-linux-gnueabihf-).
Now booting freezes before login. It detects usb stuff, but doesn't continue booting.
If I comment out the kernel= line in /boot/config.txt it boots the old kernel properly.
I tried compiling the kernel without patching and enabling PREEMPT_RT_FULL, just enabling touchscreen support. That works just fine.
Does anyone have an idea what to try next?
Any help is appreciated.
