Hi, I'm trying to set up my UDOO Quad for the first time. Where do the jumpers go? I think I may have fiddled with them, and I'm worried this is why it doesn't work. What I've tried so far (on ubuntu): I've formated a 4GB and 8GB SD card with FAT32. confirmed /dev/sdb1 is my SD card with df -h dd if=~/Downloads/OMV_Udoo_Quad.img of=/dev/sdb1 (8GB) dd if=~/Downloads/OpenELEC-imx6.arm-6.0.0-udoo.img of=/dev/sdb1 (4GB) sudo sync wait for the completed dd message. I've plugged in each card and plugged in the official UDOO 12V 2A power plug, a network cable in to my router and HDMI into my TV. But neither SD card work. The green LED comes on. But not network light and not signal on the TV not even a black screen. I've tried pushing and also holding the reset and power buttons. But no luck. I've tried debugging via serial by following official debug guide. But when I run: sudo minicom -w It doesn't display any feedback from the UDOO. It also says "Offline" when I press CTRL + A. It can tell if the UDOO is not there at all though. Because if I unplug the usb cable. sudo minicom -w gives an error that nothing is connected. I've also tried unscrewing the heat sync to check the memory was there. It looks fine to me. So put it back on. Please help me. Thanks, Glen.
Try the SD image writes again, but to each SD card's root block device (of=/dev/sdb) rather than a partition (of=/dev/sdb1). In addition to the root filesystem itself, image files contain boot blocks (uBoot), a partition table, and other out-of-partition data, and so need to be written starting at block 0 to the raw card.
