Hello,
after installing ubilinux4 on up2 celeron duo I am missing /dev/spidev...
Do I have to enable spi?
ubilinux@ubilinux4:~$ lsmod | grep spi
spi_pxa2xx_platform 24576 0
Thank you.

Hi Rostislav,
By default no spi device is created for user access by default. To enable access to spi from userspace you should add an acpi override on the kernel as described here: https://up-community.org/wiki/Pinout_UP2#SPI_Ports
