There some important changes in the configuration system. What is the exact model of your screen? Where did you load your touch-device driver before the update?

Thanks!

In the first post you say “capacitive” …
Please, update your software following these instructions:

Problems configuring the new official display "PiScreen2" [SOLVED]

Dear José, thank you very much… yesterday the zynthian arrived… Now it is ready! BUT! it dont work correctly with the display… I don’t know the correct settings for it. With hdmi waveshare display it boots and the controllers and all is working. Then i switched to the internal display over webinterface… The piscreen1 works sometimes after switching… But not after a reboot. After rebooting with piscreen settings the system hung… I spent ours and ours now, but not able to find a solution…

Also, you could download the last image:

http://blog.zynthian.org/download/zynthian_gorgona_edge_rbpi3_piscreen2-2017-10-23.img.torrent

and simply udpate after burning.

It comes preconfigured for the new kits, so you will need to re-configure some options for getting it to work with your hardware:

• Display: PiTFT 2.8’ Resistive
• Wiring Layout: PROTOTYPE-4
• Font Size: 10

There is no “real” error. This message is normal and i should remove it:

cp: cannot stat ‘/zynthian/zynthian-sys/etc/udev/rules.d/*’: No such file or directory

Everything seems to be correctly updated
