I have tried with several images (minimal, sato, lsb, lsb-sdk, full-cmdline) with the same result. This was using sysvinit. The NUC model is D54250WYK. Steps to reproduce: 1. Set MACHINE to: "genericx86-64" or "intel-corei7-64" 2. Build core-image-minimal 3. Use wic to create an EFI image (wic create mkefidisk -e core-image-minimal) 4. Copy the image to a flash drive with dd 5. Boot the image in a NUC 56836 1 daniel.alexandrux.istrate 2015-11-27 09:53:51 +0000 Tested on master: 03f15e51998a3ef65a5b68cb7cbf724f4388c289 I tried to reproduce this bug on Ed's behalf on NUC (D54250WYA) and it successfully booted. I had to update the mkefidisk wks (sda --> sdb) MACHINE = "intel-corei7-64" I tried also with this wks config: part /boot --source bootimg-efi --sourceparams="loader=grub-efi" --ondisk sda --label msdos --active --align 1024 part / --source rootfs --ondisk sda --fstype=ext4 --label platform --align 1024 --use-uuid part swap --ondisk sda --size 44 --label swap1 --fstype=swap bootloader --ptable gpt --timeout=10 --append="rootwait rootfstype=ext4 console=ttyPCH0,115200 console=tty0 vmalloc=256MB snd-hda-intel.enable_msi=0" and it worked too. --Daniel 56837 2 eduard.bartosh 2015-11-27 09:56:22 +0000 Mariano, can you try uuid configuration showed by Daniel with your device? 56904 3 mariano.lopez 2015-12-01 17:18:53 +0000 I tried to create the image adding --use-uuid and I got this error: wic create mkefidisk -e core-image-minimal Checking basic build environment...

PS: This looks quite strange ans uuid-related options are tested by oe-selftest, so they should always work. 56938 5 mariano.lopez 2015-12-02 13:31:16 +0000 Here is the diff: diff --git a/scripts/lib/wic/canned-wks/mkefidisk.wks b/scripts/lib/wic/canned-wks/mkefidisk.wks index 696e94e..a774c76 100644 --- a/scripts/lib/wic/canned-wks/mkefidisk.wks +++ b/scripts/lib/wic/canned-wks/mkefidisk.wks @@ -4,7 +4,7 @@ part /boot --source bootimg-efi --sourceparams="loader=grub-efi" --ondisk sda --label msdos --active --align 1024 -part / --source rootfs --ondisk sda --fstype=ext4 --label platform --align 1024 +part / --source rootfs --ondisk sda --fstype=ext4 --label platform --align 1024 --use-uuid part swap --ondisk sda --size 44 --label swap1 --fstype=swap 56947 6 eduard.bartosh 2015-12-02 15:40:46 +0000 I can't reproduce it. Which machine do you use? Can you show your bblayers.conf? according to gfdisk manual return code 3 means that Non-GPT disk detected and no -g option. It looks like a bug, but I have to reproduce it to be able to fix. 56948 7 eduard.bartosh 2015-12-02 15:57:00 +0000 Mariano, you should add --ptable gpt option to bootloader line in your .wks Sorry for not noticing it before. 56969 8 mariano.lopez 2015-12-02 21:18:18 +0000 It booted fine with the --use-uuid option 56975 9 eduard.bartosh 2015-12-03 08:52:43 +0000 Can you try to use sdb instead of sda in original wks(without --uurd and --ptable gpt) ?

The NUC I'm using for testing has an SSD, and the SSD is the "sda". When booting from the USB the the kernel will look for a partition in the SSD and not in the USB. This has to do with the NUC configuration and not a problem with wic. Closing as not a bug 57037 11 eduard.bartosh 2015-12-04 10:17:25 +0000 Mariano, have you tried to change sda->sdb in your .wks? Did it solve the issue, i.e. did the image boot? 57558 12 bogdanx.a.voiculescu 2016-01-06 09:39:58 +0000 Verified on above comments.
