Partprobe not working #30

Open jorgeasmz opened 8 months ago

jorgeasmz commented 8 months ago

Hello,

I'm currently following the guide to build the Linux Embbeded System for the DE10-Nano. All the steps worked for me, until I got to the part of Creating the SD Card Image. The problem I got there is that after writing the partitions using fdisk and doing

sudo partprobe /dev/loop0

I get the following error:

~/sdcard$ sudo partprobe /dev/loop0 Error: Partition(s) 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64 on /dev/loop0 have been written, but we have been unable to inform the kernel of the change, probably because it/they are in use. As a result, the old partition(s) will remain in use. You should reboot now before making further changes.

I'm doing this tutotial using WSL on Windows 11, specifically 'Ubuntu 22.04.4 LTS on Windows 10 x86_64' and kernel '5.15.133.1-microsoft-standard-WSL2'. I'm not sure what the problem is there. I would appreciate the help.

I haven't done this on WSL so not sure if there's something going on with that. It worked fine for me on Virtualbox though.

Really not sure what's going on here. Have you tried creating the image a second time? Are you getting the same error?

Hello,

Yes, I have actually recreated multiple times this step, but it doesn't change. I ended up installing the Debian for DE10-Nano v5.12 on my SDCard from the releases, but I obtained another error. It is regarding to file transfer. When I do ifconfig in the DE10-Nano (using PuTTY), I don't get an IP address. Instead I get this:

I don't know what the problem is here.

same here, have you found any solution?

I did not find a solution for the partprobe error, but I did get a solution for the IPv4 address problem. The way I solved it was by using a static IP address. I modified the file 'interfaces' as follows:

sudo nano /etc/network/interfaces

Then paste the following:

# interfaces(5) file used by ifup(8) and ifdown(8)
# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d

auto lo eth0
allow-hotplug eth0
iface lo inet loopback

iface eth0 inet static
    address 192.168.27.2
    netmask 255.255.255.0
    gateway 192.168.27.1

Since I'm using this in a local environment, it is sufficient for me to have a static IP address. I only needed it to transfer files usinc scp command.

I've found a solution online. Actually losetup is sufficient for this task. After partitioning with fdisk you can run this command instead of partprobe:

sudo losetup -P /dev/loop0 sdcard.img

P.S. Issue on WSL repo about this problem is opened since 2017
