I'm trying to enable DM verity on the udoo neo. I went into make menuconfig-->Device Drivers--> enabled Multiple devices driver support (RAID and LVM)--> modularized Device Mapper Support--> modularized Verity target support the command i'm trying to run to create a verity device is: veritysetup --debug format /dev/mmcblk0p2 /dev/mmcblk0p2 --hash-offset=15896969216--salt=123456789123456789 the number of blocks in /dev/mmcblk0p2 is 3881088, and I've tested this command on a test filesystem--and it worked. The hash-offset is correct, but I'm getting a cannot seek to requested position error. Can someone please help me?
