Topic: zJATAG /dev/parport0: No such device or address

Im trying to run debrick utility zJATAG but it cant find parport0, Im thinking that interface name has been changed and what I can do now to access parallel port ?

$ ./zjtag -backup:cfe /diygadgetblackcat

        ==============================================
               zJTAG EJTAG Debrick Utility v1.8 RC3
        ==============================================

cable=blackcat, cabletype=2

Failed to open /dev/parport0: Permission denied

and as sudo

 $ sudo ./zjtag -backup:cfe /diygadgetblackcat

        ==============================================
               zJTAG EJTAG Debrick Utility v1.8 RC3
        ==============================================

cable=blackcat, cabletype=2

Failed to lock /dev/parport0: No such device or address

and here is lsmod

     /sbin/lsmod | grep parport
    parport_pc             32768  1
    parport                49152  3 lp,ppdev,parport_pc

Re: zJATAG /dev/parport0: No such device or address

You seem to have a problem with file permissions. Check the output of

ls -l /dev/parport0

As root, you can add rw permissions witch chmod.

Ok here it is

ls -ls /dev/parport0 
0 crw-rw-r-- 1 root lp 99, 0 јан 12 22:00 /dev/parport0

I did tried as root as well but same deal, dont know what happening

Re: zJATAG /dev/parport0: No such device or address

The solution is

sudo rmmod lp
