After compiling, transplant all files from / TMP / udev / udev – 126 / build / directory to ARM board and start the udev process
# /usr/sbin/udevd
# ps -elf |grep udev 399 root 0:02 /usr/sbin/udevd 986 root 0:00 grep udev
Check that the process has started and write some udev rules to verify it.
# udevd --debug [1090] init_udevd_socket: bind failed: Address already in use another udev daemon already running [1090] main: another udev daemon already running
# udevadm test /sys/class/net/eth0 This program is for debugging only, it does not run any program, specified by a RUN key. It may show incorrect results, because some values may be different, or not available at a simulation run. parse_file: reading '/etc/udev/rules.d/11-add-usb.rules' as rules file udevtest: run: '/bin/bash /mnt/system/udev/usb.sh'
