I will give that a go in the evening - just checked and I'm running ext3 on my sd card: root@udoo:~# fsck -N /dev/mmcblk0p1 fsck from util-linux 2.25.2 [/sbin/fsck.ext3 (1) -- /dev/mmcblk0p1] fsck.ext3 /dev/mmcblk0p1 so I'm guessing I have to change ext4 to 3 in the setenv command? setenv bootargs root=/dev/mmcblk0p1 rootfstype=ext3 rootwait console=ttymxc1,115200

Thank you for all your help so far.

Any suggestions where I am going wrong?

No, on my existing debian installation.

I was trying to install the udoo kernel but got stuck with this error: root@udoo:/tmp/4.0.8# ls -la total 32968 drwxr-xr-x 2 root root 4096 Jul 29 14:21 . drwxrwxrwx 5 root root 4096 Jul 29 14:21 .. -rw-r--r-- 1 root root 16875520 Jul 13 11:30 4.0.8-udoo-next.tar -rw-r--r-- 1 root root 11204 Jul 13 11:30 linux-dtb-4.0.8-udoo_1.8_armhf.db -rw-r--r-- 1 root root 49792 Jul 13 11:30 linux-firmware-image-4.0.8-udoo_b -rw-r--r-- 1 root root 6844194 Jul 13 11:30 linux-headers-4.0.8-udoo_1.8_armb -rw-r--r-- 1 root root 9096354 Jul 13 11:30 linux-image-4.0.8-udoo_1.8_armhfb -rw-r--r-- 1 root root 769836 Jul 13 11:30 linux-libc-dev_1.8_armhf.deb -rw-r--r-- 1 root root 97604 Jul 13 11:30 linux-u-boot-4.0.8-udoo_1.8_armhb root@udoo:/tmp/4.0.8# dpkg -i linux-image-4.0.8-udoo_1.8_armhf.deb dpkg: error processing archive linux-image-4.0.8-udoo_1.8_armhf.deb (--install): package architecture (armhf) does not match system (armel) Errors were encountered while processing: linux-image-4.0.8-udoo_1.8_armhf.deb Am I using the right package for udoo quad?
