I am trying to create partition of SD card, for this  I am following this tutorial. When I type the commandll /dev/mmcblk*I got this ls: cannot access /dev/mmcblk*: No such file or directorySo, I check the list of items in /dev by typing this commandls /dev/I got a big list of items but there is nothing like mmcblk0 or mmcblk1. The list I am getting is thisautofs           dvdrw     loop4               psaux  ram6    sdb       tty10  tty24  tty38  tty51  tty8       ttyS2   ttyS5    vcs6block            ecryptfs  loop5               ptmx   ram7    sdb1      tty11  tty25  tty39  tty52  tty9       ttyS20  ttyS6    vcs7bsg              fb0       loop6               pts    ram8    sg0       tty12  tty26  tty4   tty53  ttyprintk  ttyS21  ttyS7    vcsabtrfs-control    fd        loop7               ram0   ram9    sg1       tty13  tty27  tty40  tty54  ttyS0      ttyS22  ttyS8    vcsa1bus              full      loop-control        ram1   random  sg2       tty14  tty28  tty41  tty55  ttyS1      ttyS23  ttyS9    vcsa2cdrom            fuse      mapper              ram10  rfkill  shm       tty15  tty29  tty42  tty56  ttyS10     ttyS24  uhid     vcsa3cdrw             hidraw0   mcelog              ram11  rtc     snapshot  tty16  tty3   tty43  tty57  ttyS11     ttyS25  uinput   vcsa4char             hpet      mei                 ram12  rtc0    snd       tty17  tty30  tty44  tty58  ttyS12     ttyS26  urandom  vcsa5console          input     mem                 ram13  sda     sr0       tty18  tty31  tty45  tty59  ttyS13     ttyS27  v4l      vcsa6core             kmsg      net                 ram14  sda1    stderr    tty19  tty32  tty46  tty6   ttyS14     ttyS28  vcs      vcsa7cpu              log       network_latency     ram15  sda2    stdin     tty2   tty33  tty47  tty60  ttyS15     ttyS29  vcs1     vga_arbitercpu_dma_latency  loop0     network_throughput  ram2   sda3    stdout    tty20  tty34  tty48  tty61  ttyS16     ttyS3   vcs2     vhost-netdisk             loop1     null                ram3   sda4    tty       tty21  tty35  tty49  tty62  ttyS17     ttyS30  vcs3     video0dri              loop2     port                ram4   sda5    tty0      tty22  tty36  tty5   tty63  ttyS18     ttyS31  vcs4     zerodvd              loop3     ppp                 ram5   sda6    tty1      tty23  tty37  tty50  tty7   ttyS19     ttyS4   vcs5I have followed this tutorial before but I do not any idea what's wrong this time. So,please tell how to get mmcblk list.
Locating the /dev entry to make partitions on an SD card
linux;partition;block device;sd card
The SD card is not necessary visible as /dev/mmcblk*. Another possibility is /dev/sd*.You can find name the either by looking into the dmesg output. Other way is to eject card, type ls /dev, insert card, do ls /dev again and find the difference.
