I'm trying to install an SD card with the jessie image for my Raspberry Pi 3 that will work in remote (without screen). The card is formated in FAT32 with
gparted (I use Xubuntu).
My problem is that
usb-creator-gtk returns an error "Unable to write image to disk" when I want to install the
If I try with
unetbootin it ends well and file seems to be copied properly but as you can see there are only 5 files included one
ubninit of 4Go. It seems that only one partition of the image file is writen to the disk but the other partition remains an archive. When I insert the card in my Pi 3 the led indicator is red (no blinking, no green).
vivaldi@vivaldi-SATELLITE-C670-11X:~/Téléchargements$ ll /mnt/sdb1 total 3939456 drwxr-xr-x 2 root root 4096 janv. 1 1970 ./ drwxr-xr-x 5 root root 4096 avril 18 14:53 ../ -r-xr-xr-x 1 root root 32768 avril 18 16:11 ldlinux.sys* -rwxr-xr-x 1 root root 55012 avril 18 16:11 menu.c32* -rwxr-xr-x 1 root root 145 avril 18 16:11 syslinux.cfg* -rwxr-xr-x 1 root root 4033871872 avril 18 16:11 ubninit* -rwxr-xr-x 1 root root 26140 avril 18 16:02 ubnkern*
Last, I try with :
dd if=2016-03-18-raspbian-jessie.img of=/dev/sdb1 bs=4M dd bs=4M if=/dev/sdb1 of=from-sd-card.img truncate --reference 2016-03-18-raspbian-jessie.img from-sd-card.img diff -s from-sd-card.img 2016-03-18-raspbian-jessie.img
dd returns no error and
diff report that the files are identical but my problem is that I'm unable to mount the card after this to check the data are copied properly :
vivaldi@vivaldi-SATELLITE-C670-11X:~/Téléchargements$ fdisk -l /dev/sdb1 Impossible d'ouvrir /dev/sdb1
fdisk -l to find start block in order to mount with the
-o offset=xxxx option.
My second problem is that the LED indicator is red on when I insert the SD card in the Pi 3, which mean it cannot find the boot loader.
I have no idea what to do now, what could be the reason for all these failures ?
