I am following the quick start instructions for the nanopi. I am using a sandisk 8gb micro sd card. When I run the sd-fuser I get an incompatible device error. I tried using the sd-fuser in Fedora and Ubuntu. The sd comes up as dev/mmcblk0 Also, just an fyi, the git repo is slow to clone at least for me in the states. I gave up and just went to the web and downloaded the zip. Thanks for your help, Dustin
Just guessing ... but have you formatted this card before? Maybe, try a Windows format and then determine what the /dev/sd? is. Maybe you can sudo dd if=/dev/zero /dev/mmcblk0 (haven't tried that before)
Got it working. The fusing.sh is looping to look for the device. My sd card is /dev/mmcblk0/ I am not sure if there is a way to change but I was able to modify to find mine Changed line 52 from: /dev/sd[a-z] | /dev/loop0) To this: /dev/mmcblk[0-9] | /dev/loop0) Unless I am mistaken, the original line would allow fusing to run using on any drive that starts with /dev/sd This would include my hard drive partitions. Am I right about this? Maybe a pattern matching that would ensure only sdb or sdc or mmcblk as acceptable would be better.
Just guessing again ... that line possibly identifies any new devices plugged in. Hopefully not your hard drive! I think there is some reason for it being identified as mmcbkl0 rather than sdb, sdc, etc Switching over to Ubuntu ....
Years ago when formatting SD cards so that the kernel went into an unformatted partition and the rootfs into an ext4 partition the card was found at /dev/mmcblkp0. I recall that a few years ago things seemed to change to /dev/sdx. fusing.sh in sd-fuse_nanopi completely sets everything to zero and places all the required files on the card. My NanoPi card says /dev/sdb That is the limit of my knowledge.
Ok, I thought I had it working but I did not. My solution was only partially loading, uboot flashed but nothing else. The failure was due to the same routine determining that whether the sd card was a supported reader. So I think the change may actually have worked but only if you make the change to all the .sh files that first "check for fusing" But I was running Fedora from a live usb which may have been why the sd was coming up mmcblk So I tried again, this time from an Ubuntu machine and it worked! One thing I do find bit confusing is that though my sd is /dev/sdb1, when running fusing.sh I have to run ./fusing/sh /dev/sdb and not /dev/sdb1 I guess I better make sure I only have one usb connected? Oh well, I am learning a lot about bash scripting in my attempts.
