Did you load the UArt kernel driver? When you configure pins from a device tree blob the kernel also loads the matching driver. In contrast, libpruio doesn't inform the kernel about changes. It's under your control to make this happen. If you're sure that you want Uart-1 on P9_24/P9_26, and that wont change, then it's best to install a custom device tree blob for that two pins. Check out the docs for section Custom overlay <http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/ChaPins.html#sSecCustom>. You can use the tool src/config/dts_custom.bas <http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/dts__custom_8bas.html> to create that blob in folder /lib/firmware. Your configuration (edit in source and compile) should look like M(P9_24) = CHR(0) > M(P9_26) = CHR(0) > Perhaps you also want to adapt the file name. When the .dtbo file is in place, edit /boot/uEnv.txt to load it and reboot.
