I'm follow an instruction on EmutexLabs, format USB and SD card to FAT32 and Extract the content of ubilinux_0.9_quark-live_usb_install.zip into USB stick; insert, connect everything to Intel Galileo. I had wait for 30 minute but the board was not power off, and when I check for sd card, it still blank.
The only OS supported by us for the Intel Galileo board is Yocto, but I’d suggest you to make sure your board has the latest firmware version. Also check the files are in the root of the USB stick and it is formatted as FAT or FAT32 as well as the SD card. If this does not work I’d suggest you to post your question in the Ubilinux Forum.
