I am working on a project and trying to make this screen work. Everything is successful except the touchscreen, during calibration is doesn't respond to any touches.
The kernel is:
Linux zynthian 4.19.97-v7l+ #2 SMP Sun Mar 29 06:27:59 BST 2020 armv7l GNU/Linux
And I am using your driver set for this kernel, the latest I could find on the net.
dmesg | grep spi - says
[ 0.188720] spi-bcm2835 fe204000.spi: could not get clk: -517
[ 0.278322] 4d-hats spi0.0: 4d-hat registered, product code = b4
I have enabled 4dpi_touch in /etc/modules as was suggested in some post - no result.
There are a couple things connected to RPi except the screen - MCP23017 and a soundcard (the screen interface is the first in the line) but removing them gives absolutely the same result.
Please advise, how to proceed further - I have no more ideas.
Thanks !
