Hi, Yesterday I have received the new QM35825DK-05. I was exitec to start working on RPi board with UWB connection but I found a problem with the linux system. It seems that it do not export the uci0 device for qm35 spi communication. Looking around the system I found the installed driver but the spi is not exported as uci0 device in /dev folder so I’m not able to run the demo scripts.
As described in the Linux kernel guide (release R3.8.0-4, section 4.1.2.2) i have to find a “misc” folder in /sys/bus/spi/devices/spi0.0 but it is missed:
qorvo@qorvo-uwb:/sys/bus/spi/devices/spi0.0 $ ll

Also the device “uci0” is missed so, ho can I communicate with the qm35 and make the demo scripts working?
Thanks in advance
