barry2212 Posted July 30, 2019 Share Posted July 30, 2019 Hi, I'm the new guy and I started use orange pi boards so go straight to the problem: I'm trying to turn my orange pi plus board into a fully function cd player.I have done the code. So when I try to connect the USB cd drive to the board and type:"ls /dev/cdrom" And it shown "ls: cannot access '/dev/cdrom': No such file or directory" that happened to "sr0" too. I don't know how to solve this Please help me.Thanks for reading this Link to comment Share on other sites More sharing options...

The URL also tells that block-device support has to be compiled in the kernel. I dont know if armbian has that block-device-support in there So with my /dev/sg0 (as yours) I only do get the following message from cdtool: root@npi-k1-plus(192.168.6.70):~# cdplay -d /dev/sg0 cdplay: can't open cdrom (/dev/sg0): not a block device. # apt-cache search cdtool cdtool - text-based audio CD player and CD-ROM control commands # apt-cache search cdcd cdcd - command line or console based CD player The following URL tells how to play audio-cd via comman line:http://www.pc-freak.net/blog/how-to-play-audio-music-cds-in-gnulinux-and-freenetopen-bsds/ Its also possible via mplayer on the commandline: mplayer cdda:// /dev/cdrom You can add a track number or range after the // (ex: cdda://1-5), if you want. [EDIT] normally armbian seems to support /dev/sr0 because of the udev-rule in /lib/udev/rules.d/50-udev-default.rules: SUBSYSTEM=="block", GROUP="disk" SUBSYSTEM=="block", KERNEL=="sr[0-9]*", GROUP="cdrom" SUBSYSTEM=="scsi_generic", SUBSYSTEMS=="scsi", ATTRS{type}=="4|5", GROUP="cdrom" KERNEL=="sch[0-9]*", GROUP="cdrom" KERNEL=="pktcdvd[0-9]*", GROUP="cdrom" KERNEL=="pktcdvd", GROUP="cdrom" Link to comment Share on other sites More sharing options...
