rpi-ft5406 module missing (touch of touchscreen not working) #223

Open zodiac612 opened 4 years ago

Hello, i installed the new kernel yesterday on my rpi4 with installed rpi 7" touchscreen. Since then the touch was no longer working.

I checked and found out that the module rpi-ft5406.ko is missing in the new folder /lib/modules/5.4.35-v7l+/kernel/drivers/input/touchscreen

After downgrading to Kernel 4.19.118-v7l+ the touch of the touchscreen is working again.

It looks like the rpi-ft5406 is missing for the latest kernel.

Thanks for the report. From the 5.4 kernel onwards, rpi-ft5406.ko has been replaced by the upstream raspberrypi_ts.ko, but doesn't help on a Pi 4 because the new config option was missing from both the 32-bit and 64-bit kernel configurations. Those omissions have been corrected in the source branches, and the module will appear in future kernel builds.
