I have generated a core-image-minimal image for my Intel board in Yocto.
Looking into tmp/deploy/images folder they are many images.
I flashed *.wic image using dd
command on USB and it created two partitions ( Boot and Platform ) and allowed only to perform a live booting without allowing it to install on the hard disk of the board.
I then flashed *.hddimg on the USB using dd
command. It only created a "boot" partition which has rootfs.img, syslinux and EFI folder.
Booting using USB provided me an "Install" option, which installed on the board and when I rebooted after installing, it displays "No bootable media found"
Using bootable image there are two partitions in the hard disk. Why it is not booting..
Steps followed:
dd
command.sudo dd if=tmp/deploy/images/intel-corei7-64/core-image-minimal-intel-corei7-64.hddimg of=/dev/sdb
What is the mistake I am doing here.
Which image to choose and when..
Windows Imaging Component Features The primary features of WIC are: Enables application developers to perform image processing operations on any image format through a single, consistent set of common interfaces, without requiring prior knowledge of specific image formats.
Image created with the J Wavelet codec wavelet compression algorithm; may be opened and converted to more common raster image formats using XnView, even though the file extension is very rare.
There was not much info about online, so I asked this question in the intel community and here is the response of that:
Generally a .wic image is intended to be installed directly to its final destination, whereas an hddimg is for evaluation and installation elsewhere.
By default meta-intel .wic images only have an EFI bootloader, and will not boot via legacy BIOS.
An hddimg will have both an EFI bootloader and the syslinux binaries that let it boot from legacy BIOS.
On startup with your installer USB image do you get a light gray screen with four options? If so it is booting via legacy BIOS.
